OPERATION
LOCKOUT
There may be times when you wish to skip over a channel that you have programmed into your
Bearcat BC172XL. Any number of channels can be "Locked Out" so that the scanner skips
over them. To Lock Out a channel, select the channel number you wish to skip over (see the
section on manual channel selection). Press the [LOCKOUT] key. The word "LOCK OUT will
appear in the display whenever that channel number appears. To cancel the lock out mode
simply select the channel manually, and then press the [LOCKOUT] key when that channel
number appears.
SCAN
To scan the channels programmed in memory, press the [SCAN] key. The channels will
automatically scan at the rate of approximately 10 channels per second. As the unit scans, the
channel digits in the display will advance rapidly, indicating the scanning mode. In order to
stop the scan mode, a transmission must be present on one of the programmed frequencies.
The" squelch control must also be set so that the transmission will "break squelch" and stop
the scan. You can also stop scanning by pressing the [MANUAL] key.
SCAN DELAY
The Bearcat BC 172XL can be programmed to pause for about 2 seconds after a
transmission ends on any channel. This is useful in preventing the continuation of scanning
when there is a slight pause in transmission. It is also useful when both sides of a conversation
are occurring on the same channel. To turn on the scan delay for a channel, select the channel
(see the section on manual channel selection). When the desired channel is displayed, press
the [DELAY] key. The word "DELAY" will then be displayed alongside the channel number.
To remove the delay, simply repeat this procedure.
ERROR MESSAGE
To inform the user that you are attempting to store an out-of-band frequency in memory, the
BC 172XL automatically displays "Error" in this event. The condition may arise when the user
presses ENTER with an invalid number in the display. The user should simply press the
[CLEAR] key, and then enter an in-band frequency (see programming section) to clear the
ERROR indication.
EARPHONE
For private listening, plug the earphone into the Earphone jack on the front of your BC 172XL.
This automatically disconnects the speaker.
WEATHER SCAN
To automatically scan for the NOAA weather frequency active in your area, just press the
[WX] key. Press [SCAN] to resume normal scanning.
PRIORITY
You may want to be alerted to a transmission on a specific frequency, even when
scanning other channels. The priority feature samples the frequency that has been
entered into Channel 1 every 3 seconds. If a signal is detected on the priority frequency,
the Scanner tunes to Channel 1 and remains until the transmission stops. At that time
the Scanner returns to the previous mode of operation.
To active the priority function: Press [PRIORITY]. The priority message is displayed.
To remove priority: Press [PRIORITY]. The message disappears.
TROUBLE-SHOOTING
If your Bearcat BC 172XL is not performing up to your expectations, please try re-reading
this guide. If you still cannot get satisfactory results after reading this guide thoroughly
and following the listed steps, you may need to send your unit in for service.
If you determine that service is necessary, remove the antenna from the unit and make
sure it is turned off. Pack the scanner in the original packing material carton. Send it
along with a brief, concise description of the problem, your name, address, phone
number and a copy of your purchase receipt to the address listed in the warranty.
HELPFUL HINTS
The following hints are provided to help you get the most out of your new scanner.
By reading this entire guide, including this section, you will better understand and enjoy
your new Bearcat BC 172XL.
1. Always remember to press the enter key when programming a frequency. If the enter
key is not pressed the frequency will not be programmed into that channel.
2. If you ever have to ship the unit, be sure to remove the antenna and place it and the
unit in the original styrofoam inner packing and box. One of the most common causes
of damage to electronic products is improper packing when shipping.
3. Remember that the liquid crystal display is subject to permanent damage if it is
exposed to extremes in temperature or humidity. Take extra care with your scanner in
the winter and on sunny, summer days.
4. Receiver sensitivity is affected by the location of the antenna and the environment that
the unit is used in. Best reception will occur when the unit is placed on a level metal
surface with the antenna pointing up. Placing the unit close to a window, will also provide
better reception.
5. Receivers, such as the Bearcat BC172XL, which have broad tuning ranges are
subject to ineterferece from internally generated signals ("Birdies') on a few receiver fre¬
quencies. On these frequencies, reception of external signals may be impaired. Nothing
is wrong with your scanner if this kind of interference occurs, unless it happens on a large
number of frequencies.
