Troubleshooting
Possible Problem (2): Operating the radio while it is close to your body (i.e. in a pocket or on a belt) and while you are using audio acces- sories decreases its range because of the shielding effect of your body.
Solution :The higher the radio is held, the better the talk range. Use of audio accessories is only recommended in close range sit- uations for best results.
Possible Problem (3): The Carrier Squelch Level may be set too high.
Solution :Set the Carrier Squelch Level to a lower value (see “Setting Squelch Level” on page 20).
You hear constant static from speaker.
Possible Problem (1): The alkaline batteries may be weak (or the NiCd battery may be dis- charged).
Solution :Press and hold the PTT while looking at the LCD. If the ‘BATT’ indicator flashes continuously while still holding the PTT, the batteries should be replaced or recharged.
Possible Problem (2): When using your radio around computers or electronic equipment, you may hear static or interference from these devices.
Solution :Enable Coded Squelch. Coded squelch screens out this type of interference (see “Changing Squelch Modes” on page 18).
