MAINTENANCE & TROUBLESHOOTING Due to its rugged design, your radio requires very little maintenance. However, it is a precision electronic instrument, so you should follow a few precautions: xx If the antenna has been damaged, do not transmit except in an emergency situation. Transmitting with a defective antenna may cause further radio damage. xx You are responsible for continued FCC technical compliance of your radio. xx You should arrange for periodic performance checks with your Uniden dealer. COMMON QUESTIONS Problem Things to Try The radio won't turn on. Charge the radio. The charging animation doesn't start. • Don't charge the radio when the ambient temperature is below 32°F (0°C) or above 113°F (45°C). • Make sure the charging contacts on the radio and charger are clean. • Replace the batteries. The radio won't transmit. I can't hear anything from the speaker. • Make sure you are not in Scan mode. • Make sure you are not trying to transmit on a receive-only channel (see the channel lists starting on page 28). • Check the battery power level; if it's low, charge the battery before trying to transmit. • Make sure the duration of each transmission is less than 3 minutes. Adjust the squelch level; it is probably too high. If the radio has fallen into water, activate the Speaker Vibration Tone (see page 24). The vibration will help remove water from the unit.
