INTRODUCTION

About Scanning

Scanning is easy and fun with the UBC248CLT 50-Channel Base Scanner with AM/FM Radio.

What is Scanning?

Unlike standard AM or FM radio stations, most 2-way communications do not transmit continuously (see Types of Communication below).

The UBC248CLT scans programmed channels at rate of up to 12 channels per second until it locates an active frequency. When the scanning stops on an active frequency, it remains on that channel as long as the transmission continues. When the transmission ends, the scanner stays on the channel for 2 more seconds, waiting for a responding transmission. If no responding transmission is detected, the scanning cycle resumes until another transmission is received.

Types of Communication

You can monitor communications such as:

??? Police and fire departments (including rescue and paramedics) ??? Business/industrial radio

??? Utilities

??? Land transportation frequencies such as trucking firms, buses, taxis, tow trucks, and railroads

??? Marine and amateur (ham radio) bands

1

???Many more in the 66-88MHz, 137-174MHz, and 406-512MHz ranges

???AM/FM radio

You must program a frequency into each channel you want to use.

Taking Proper Care of Your Scanner

???Do not use the scanner in high-moisture environments such as the kitchen or bathroom.

???Avoid placing the unit in direct sunlight or near heating elements or vents.

???Do not unplug the scanner for prolonged periods of time, lack of power will cause the clock to reset.

Scanning Overview

The UBC248CLT has 50 memory channels. Each can be programmed to store one frequency within the band of frequency coverage. (For a listing of frequency ranges and bands, see Technical Specifications on page 32.)

When you press SCAN, the UBC248CLT scans each programmed frequency for activity (skipping channels that are locked out) at the rate of about 12 channels per second. As the unit scans, the word SCAN moves across the display, and the bank number flashes.

When the scanning stops on an active frequency, it remains on that channel as long as the transmission continues. When the transmission ends, the scanning cycle resumes. If you are in the delay mode, the scanner stays on the channel for 2 more seconds, waiting for a responding transmission. If no responding transmission is detected, the scanning cycle resumes.

Searching Overview

In contrast to Scanning which monitors only a group of frequencies that are stored in the scanner???s channels, Searching monitors all the frequencies within a pre-selected range of frequencies (bound by upper and lower limits). If you find an interesting frequency while searching, you can store it in a channel for easier access later.

CLOCK SET-UP

Initial Clock Set-up

You may bypass the steps to set the clock. The scanner will function as normal, but the clock and alarm features will not function.

1. When power is initially applied, the display flashes i2:00 P after a short delay.

3. Press AM/PM to select the desired setting, either am. or pm.

4. Press E to complete the entry. The display stops flashing.

4.To set the SQUELCH control to AUTO turn fully counter clockwise until control clicks into place. Or, manually set squelch as follows:

???Think of squelch as a gate. Turn SQUELCH fully counter clockwise. This raises the ???Squelch Gate??? so high that only very strong signals can get through.

???Turn SQUELCH fully clockwise until you hear a hiss. This lowers the ???Squelch Gate??? so that everything gets through ??? noise, weak signals, and strong signals.

???Turn SQUELCH back counter clockwise until the hiss stops. Now the ???Squelch Gate??? allows only strong signals through.

Programming Tips for Scanner

???Program one frequency per channel.

???Channel 1 is the location of the default priority channel. Program the most important frequency, or the one of major interest, into Channel 1. You may also select any other channel to be the priority channel.

???To quickly program a series of channels, start with the lowest number channel. For example, when you are programming five new frequencies into Channels 4 through 8, start with Channel 4. After you complete the programming in one channel (by pressing E), press MANUAL to step up to the next channel.

Channels are grouped by banks for easy scanning control. The channels associated with

???If you make an error during programming, or the frequency is out of range, appears on the frequency display.

???If you program the same frequency in two channels, the display will indicate the channel with the duplicate frequency. If you want to have two of the same frequencies on different channels, accept the entry by pressing E again.

???During numeric entry, if you know that you pressed the wrong number,

press . (decimal point) until the entry is cancelled out. When the previous frequency is displayed, you may re-enter the frequency.

???Above 406MHz, the frequency steps are in 12.5kHz increments. To enter a frequency such as 450.4875, press each of the seven digits in sequence.

If All Loc Out appears in the display, when you first turn the scanner on, this indicates that all the channel information has been manually erased. All channels are set to 0.0MHz. To clear this message, program the frequency and channel information as desired.
