Care
Keep the scanner dry and away from water; do not wash the scanner with
a wet cloth or pour fluid into the scanner. Use and store the scanner only
in normal temperature environments. Handle the scanner carefully; do not
drop it. Keep the scanner away from dust and dirt, and wipe it with a damp
cloth occasionally to keep it looking new.
Modifying or tampering with the scanner’s internal components can cause a
malfunction and might invalidate its warranty and void your FCC authoriza-
tion to operate it.
The radio design of the tuning, control and filtering circuitry on the receiver
is controlled by the serial data from the firmware code in the microprocessor,
which is built-in by the microprocessor manufacture as a part of the internal
design of the processor. Since the processor information is inaccessible to
the user, if someone attempt modifying circuitry without the knowledge of
the firmware code, the radio simply will fail to operate.
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 scan-
