Uniden bc780hlt manual


















Following a conversation on a trunked system using a scanner is difficult, if not impossible. This type of scanning is difficult and frustrating.

Not only does your new BCXLT scan channels like a conventional scanner, it actually follows the users of a trunked radio system. If you're a new scanner enthusiast, you may want to read the first part of this manual and use your scanner in conventional mode before you begin trunk tracking. Understanding scanning fundamentals and its terminology will make trunk tracking much easier.

A glossary of other commonly used terms is provided in the back. But if you're already an experienced scanner operator, you may want to skip to Trunked System on page Scan conventional and trunked systems at the same time. You must have at least one channel programmed to use the Scan mode. Note : The frequency coverage is not continuous and excludes the cellular band, MHz.

Assigning a priority channel allows you to keep track of activity on your most important channel s while monitoring other channels for transmissions. You can also assign trunking priority talkgroups. No PC required. This applies only to transmission bands with 5 kHz steps. Before using your scanner, you must program frequencies into available channels. Central Time Monday through Friday. To obtain additional frequency information for your area, contact one of the following:.

Eastern Time Monday through Friday. If you have access to the Internet, you may want to visit www. A special website has been specifically setup for this scanner with helpful information on using this scanner and other user comments. Visit www.

You must install an antenna before you can operate the scanner.

You have been provided a standard telescopic antenna that works well with this scanner, but you may want to purchases another type to increase the range. You can purchase a variety of scanner antennas for both mobile and base station available at a local electronics store.

Choose the one that best meets your needs. When deciding on a mobile or base station antenna and its location, consider these points. Once you choose an antenna, follow the mounting instructions supplied with the antenna.

Then route the antenna cable to the scanner. The antenna connector on your scanner makes it easy to use the scanner with a variety of antennas, such as an external mobile antenna or an outdoor base station antenna. Always use 50 ohm coaxial cable, such as RG or RG-8, to connect an outdoor antenna. For lengths over 50 feet, use RG-8 low-loss dielectric coaxial cable.

Follow the Installation instructions supplied with the antenna, route the antenna cable to the scanner, then connect it to the ANT. Warning : Use extreme caution when you install or remove an outdoor antenna. If the antenna starts to fall, let it go! It could contact overhead power lines. If the antenna touches a power line, contact with the antenna, mast, cable, or guy wires can cause electrocution and death.

Call the power company to remove the antenna. DO NOT attempt to do it yourself. If you have chosen an optional mobile antenna, connect the antenna plug into the ANT connector on the rear of the scanner. For more information on antenna installation, please refer to the instruction guide that came with your antenna.

The BCXLT can be conveniently mounted on a table, bulkhead, overhead, or any other desired location refer to figure below for typical mounting methods. Caution : Make sure there are no hidden electrical wires or other items behind the desired location before proceeding. Check that free access for mounting and cabling. Before you mount the scanner, make sure you have all the necessary materials. Caution : Be sure to avoid obstructions behind the mounting surface. Choose a mounting location, then use the supplied mounting bracket as a template to mark the positions for the mounting screw holes.

In the marked positions, drill holes slightly smaller than the supplied screws. Attach the mounting bracket to the mounting location using the supplied screws and lock washers. Attach the scanner to the mounting bracket using the supplied mounting knobs. Caution : You must use a power source that supplies Your standard 12V car battery should be sufficient. The supplied DC power cord meets these specifications. Using a power cord that does not meet these specifications could damage the scanner or the adapter.

When you finish, disconnect the adapter or DC power cord from the power source before you disconnect it from the scanner. Be sure that the screw is not insulated. To connect the supplied DC cigarette-lighter power cord, insert its barrel plug into the DC This is normal. You can place this scanner on a desk, shelf, or table to use it as a base station. Extend the antenna to full vertical position.

Adjust the angle for best reception. To power the scanner from an AC outlet, use the provided AC adapter with a 5. Caution : You must use a Class 2 power source that supplies Using an adapter that does not meet these specifications could damage the scanner or the adapter.

When you finish, disconnect the adapter from the AC power before you disconnect it from the scanner. Plug the adapter into a standard AC outlet. Note : Use only the AC adapter supplied with your scanner.

In a noisy area, an external speaker available at a local electronics store positioned in the right place might provide more comfortable listening. Your local electronics store should carry a wide selection of earphones. Once the earphone is connected, it will automatically disconnects the internal speaker. To protect your hearing, follow these guidelines when you use an earphone or headphones.

The volume is not adjustable and damage to your hearing could occur. Extended high volume listening can lead to permanent hearing loss. Over time, your ears adapt to the volume level, so a volume level that does not cause discomfort might still damage your hearing. You can also upload or download the programmed data to or from a PC using an optional PC interface kit available through your local electronics store.

Your local electronics store should carry a wide selection of cables and tape recorders. The LINE icon appears on all channels that have been properly marked. Do not set the volume on minimum. Make a trial taping to be certain the volume levels are set correctly.

Software for remote programming and controlling the scanner is available for purchase by calling or through the website www. The scanner automatically starts scanning.

Since there are no frequencies programmed in your scanner initially, you may not receive any signals. Once you set the squelch and program some frequencies, you will be hearing conversations regularly. To set the squelch, you must be in the Manual mode, and you should not be receiving a signal on your scanner. Think of the Squelch Control as a gate.

Next you must program some frequencies. It is very important for you to understand the Menu screen. To navigate through the Menu screen is really quite simple. Many of the features of this scanner, can only be accessed by the menu screens. There are several ways to get through the screens. First of all, press MENU to get started. When you select frequency bands to search, the scanner searches for any active frequency within the lower and upper limits you specify.

When the scanner finds an active frequency, it stops on that frequency as long as the transmission lasts. If you think the frequency is interesting, you can program it into one of the banks.

If not, you can continue to search. Conventional scanning is a relatively simple concept. Each group of users in a conventional system is assigned a single frequency for simplex systems or two frequencies for repeater systems. Any time one of them transmits, their transmission always goes out on the same frequency.

Even today, there are many 2-way radio users who operate using a conventional system:. When you want to store a conventional system, all you need to know is the frequencies they operate on. When you are scanning a conventional system, the scanner stops very briefly on each channel to see if there is activity. If there is, then the scanner pauses on the transmission until it is over. Simplex systems use a single frequency for both transmit and receive. Most radios using this type of operation are limited to line-of-sight operation.

The range is typically miles, depending upon the terrain and many other factors. Repeater systems use two frequencies: one transmits from the radio to a central repeater; the other transmits from the repeater to other radios in the system. With a repeater-based system, the repeater is located on top of a tall building or on a radio tower that provides great visibility to the area of operation.

When a user transmits on an input frequency , the signal is picked up by the repeater and retransmitted on an output frequency. Since the repeater is located very high, there is a very large line of sight. Typical repeater systems provide coverage out to about a mile radius from the repeater location. By itself, this manual really only provides part of what you need to know to have fun scanning — how to program and use the scanner.

The included conventional frequency guide will give you a good head start on the other part of what you need to know — what frequencies have interesting content. The Internet is a great source for current frequencies and information about scanning. Many web sites have lists of frequencies for your area. You can use a search engine to find and use them. Make a list of the agencies you want to listen to, then look up the frequencies and systems used by those agencies.

Here are a few useful sites:. Eastern Time Monday through Friday. To purchase another copy of the conventional frequency guide, contact your local dealer or:. If any of these items are missing or damaged, immediately contact your place of purchase or Uniden Customer Service at: , a. You might also try changing the height or angle of the telescoping antenna. You can purchase this type of antenna at a local electronics store.

If the optional antenna has no cable, use ohm coaxial cable for lead-in. A mating plug might be necessary for the optional antennas. Read the precautions on the inside front cover of this Owners Manual. You can power your scanner using two alkaline or rechargeable AA batteries not supplied. Make sure the power is turned off. Slide the battery compartment cover. Before you install alkaline or any other nonrechargeable batteries, use a pointed object such as a ballpoint pen to set REG.

Set REG. Never attempt to recharge non-rechargeable. Non-rechargeable batteries can get hot or burst if you try to recharge them. Welcome to ManualMachine. I wanted the tape-out audio level to be the same even when I change the main speaker volume.

I stream the tape-out audio to Zello for me to listen and when I am not using Zello on the go I listen to the unit itself and sometimes I need to change the volume but I don't want to change the stream audio level.

Just wondering if there is a way. Last edited: Oct 7, These are fixed line out you can run it to a separate amp that has a line in. Ubbe Member. Storefrequenciesinto5banksof 10channelseach. Unlike standardAM or FM radiostations, most two-way communications listedonthispage donot transmit continuously. Scanning stopson anactive frequency, andremainsonthat channel aslongasthe transmissioncontinues. Whenthetransmissionends, thescanningcycle resumesuntil another transmissionisreceived. Thisgives youtheopportunity to findnew frequenciesthat havenot beenprogrammed.

You must have at least one channel programmed to use the Scan mode. The frequency coverage is not totally continuous from 29 MHz to MHz. Keep track of the activity on most important channel s while monitoring others. Manual Channel Access — Go directly to any channel. Memory Backup — Frequencies programmed in the channels are retained in memory. If the power is disconnected, the memory retains the frequencies for 7 days.

Preset 2-Second Delay — Scanner waits 2 seconds after transmission stops before resuming scanning. Do not plug the scanner into an outlet controlled by a wall switch as prolonged periods without power causes scanner memory loss.

Before you can scan, you must program a frequency into each channel you want to use. A Uniden representative should be able to provide you with a few sample frequencies. Or, use the enclosed order form to purchase a local frequency list. The Bearcat Radio Club and other similar hobby clubs have publications, information on computer bulletin boards, and even contests for the radio enthusiast.

Also, your local library has more information. Do not mix alkaline batteries with nickel-cadmium batteries. Be sure to install 4 batteries of the same type.

Do not charge alkaline batteries in this scanner.
