Troubleshooting

• Notenough range
  Cause: Line of sight blocked
  Increase antenna height.

• Will not transmit on 5 Watt range but will transmit on the
  1Watt range.
  Cause: Low voltage
  Recharge or replace the batteries.

• Will not transmit while charging
  Cause: Low voltage
  The radio is not designed to transmit while charging.
  DC or AC adaptor does not supply enough power for transmitting.

• Battery will not charge
  Cause: Low voltage
  Do not to transmit while charging.
  The adaptor does not supply enough power for transmitting.
