PROGRAMMING YOUR SCANNER
1. To program 162.550 into channel 1:
Press [MANUAL][1][MANUAL]. This causes the scanner to enter manual mode and go
directly to channel 1.
Press [PROGRAM]. The channel number will start to blink, indicating programming mode is
now activated.
Press [1][6][2][.][5][5][ENTER].
(Final zeros to the right of the decimal point will be entered automatically.)
The display will show the frequency and channel number (channel 1).
Press [MANUAL] or [SCAN] to exit programming mode. If you press the [PROGRAM] key
again, the scanner will move up to the next channel, and remain in programming mode for
easy entry of another frequency.
2. To program 471.2375 into channel 5:
Press [MANUAL][5][MANUAL]. This causes the scanner to enter manual mode and go
directly to channel 5.
Press [PROGRAM]. The channel number will start to blink, indicating programming mode is
now activated.
Press [4][7][1][.][2][3][7][5][ENTER].
The display will show the frequency (rounded off to 3 decimal places) and channel number
(channel 5).
Press [MANUAL] or [SCAN] to exit programming mode. If you press the [PROGRAM] key
again, the scanner will move up to the next channel, and remain in programming mode for
easy entry of another frequency.
If you attempt to enter a frequency outside the range of the Bearcat BC172XL, the display will
show "Error". If this happens, simply press [CLEAR] and then re-enter the correct number.
The Bearcat BC 172XL has been designed to automatically enter trailing zeros. For all
frequencies, YOU MUST PRESS THE DECIMAL POINT or "Error" will appear.
When first turned on after the purchase, a test frequencies may be found in each of the
channels. When you program your own frequencies, these test frequencies will be erased.
SEARCH MODE
The BC 172XL has a search mode that is very useful for finding new or unpublished
frequencies. To enter search mode, proceed as follows:
1. To search from 460.000 MHz to 461 MHz
Press [PROGRAM][LIMIT)[CLEAR]. The scanner will enter programming mode, with the
search frequency display reset to zero, and the unit ready for entry of the lower limit.
Press [4][6][0][.][ENTER].
The display will show "Lo 460.000". This means that 460.000 MHz has been programmed in
as the lower limit of the search.
Press [LIMIT].
The display will show "Hi 000.000".
Press [4][6][1][.][ENTER].
The display will show "Hi 461.000". This means that 461.000 MHz has been programmed in
as the upper limit of the search.
At this point, pressing [
A
] will start the searching frequencies from the lower limit to the
upper limit, or [ \y ] will start searching frequencies from the upper limit to the lower limit. To
return to normal scanning, simply press the [SCAN] key.
If the unit stops on a frequency during search mode, and you wish to temporarily stop on that
frequency, press the [MONITOR] key. To resume searching, press either the
[A
] or [
\J
]
buttons.
SQUELCH
The squelch function controls the sensitivity of the receiver. It adjusts the level at which the
scan mode will stop to receive a transmission on any frequency. Rotate the "SQUELCH"
control clockwise until you hear background noise and then turn it back counterclockwise until
the noise is silenced. This will set the scanner to receive any transmission above the level of
background noise. You can adjust the squelch level to pick up more distant signals by turning
it clockwise, or less distant by turning it back. Alternatively, you can turn the squelch control
fully counterclockwise until you hear a click. This engages the auto-squelch, eliminating any
need to set the squelch manually.
MANUAL CHANNEL SELECTION
If you wish to select a channel manually, press [MANUAL], the desired channel number,
then [MANUAL] again. The unit will then display the channel number and frequency for the
desired channel. If you press the [MANUAL] key again, the unit will step up to the next
channel.
