Scan channels you have programmed Scan pre-programmed weather channels. Unlike standard AM or FM radio stations, most 2-way communications (see "Types of Communication" below) do not transmit continuously. The UBC144XL T scans programmed channels at the rate of about 15 channels per second until it locates an active frequency.

;:::::;;:: Scanning Overview The UBC144XLT has 16 memory channels, each of which can be programmed to store 1 frequency within the band of frequency coverage. (For a listing of frequency ranges and bands, see "Technical Specifications" on page 16.) When you press C. SCAN),each of the programmed frequencies is scanned for an active frequency (channels that are locked out are skipped) at the rate of about 15 channels per second.
Adjusting the Squelch ~\ Open the squelch by turning SQUELCHclockwise to position 8 or 9. You should hear a steady sound (scanning stops). Now turn SQUELCHcounterclockwise slowly until the sound disappears. This is the threshold point at which scanning starts. At the squelch threshold, an incoming signal just slightly stronger than the noise will open the squelch. When squelch is open, you can hear the broadcast (scanning is stopped).
<::: Programming Frequencies Before you can use your UBC144XL Tt you must follow these steps to program the channels, except weather frequencies. Example: Program 420.150 MHz into Channel 12.

Each digit of the frequency is displayed individually, and then the channel number returns. Repeat these steps to review additional frequencies in the other channels. Nbte .

<:::::c Priority Scanning Your UBC144XL T has fixed Priority Channel, Channel I. Priority Scan works like a "dual watch" function. When you activate Priority Scan mode, the scanner starts "sampling," or keeping track of the activity on Channel 1 while listening to other channels. Every 2 seconds, the scanner checks Channel 1 for activity. If a signal is present, Channel 1 will be monitored until the transmission ends, and a constant "P" appears on the channel display.
Restoring a LockedOut Channel To unlock a channel so that it can be monitored during scanning: Use 0ANUA0 to find the locked out channel. SCAN REVIE Press ~ to unlock the displayed channel. The LOCKOUT LED for the displayed channel turns off. I Downloaded from www.Manualslib.
