GRE 0716 - Troubleshooting; Troubleshooting Chart; Initializing Global Parameters to Factory Defaults

Troubleshooting
If you have problems with your scanner, please refer to the following chart for
some suggestions that might help you eliminate the problem. If the scanner is still
not operating correctly after trying these tips, contact the dealer where you
purchased your scanner for assistance.
Troubleshooting Chart
Problem Possible Cause Remedy
Poor reception Weak signals from distant stations Reposition radio for best
reception
A
ttenuator in use on weak signals Check performance with and
without attenuator activated, use
setting with best reception
Strong signal overload from nearby
transmitter(s)
Check performance with and
without attenuator activated, use
setting with best reception
Scanner will not power on
A
C or DC power supply not
properly connected
Check connection to AC or DC
power source
The keypad does not work
The scanner may need to be
initialized
Follow steps below to initialize
the scanner
Scanner will not scan when
SCAN key is pressed
Possible “birdie” frequency
programmed
Tighten squelch, apply attenuator
or lock out the “birdie” frequency
The scanner may need to be reset
or initialized
Follow steps to reset/reinitialize
the scanner following this table
No channels programmed, or only
one channel programmed, or all
channels locked out
Ensure that the scanner has
more than one channel
programmed and enabled for
scanning
SQUELCH control is not adjusted
properly
Turn SQUELCH control
clockwise until scanning resumes
The scanner does not
receive digital
transmissions on digital
frequencies or trunking
systems
The digital channel or talkgroup is
not using APCO-25 digital
modulation
The scanner can only receive
A
PCO-25 C4FM/CQPSK IMBE
digital signals
The digital channel or talkgroup is
encrypted
The scanner will not receive
encrypted traffic
The digital channel or talkgroup is
being transmitted from a distant
location
Reposition the scanner or use an
outdoor antenna to improve
reception
Initializing Global Parameters to Factory Defaults
If your scanner does not appear to be functioning properly, you
can reset the global radio parameters to their factory state
without
losing any of your programmed data. Any custom
changes you have made to the radios global parameters will be
lost.
NOTE: This procedure preserves the information you stored in the scanner s working
memory, while resetting all global radio parameters to factory defaults.
V-Scanner memory is not affected by this operation.
