When condensation occurs, the microcomputer and/or the transmit/receive circuits may become unstable, resulting in transceiver malfunction. If this happens, turn OFF the transceiver and wait for a while. When the condensed droplets disappear, the transceiver will function normally. PRECAUTIONS Please observe the following precautions to prevent fire, personal injury, and/or transceiver damage: Do not attempt to configure your transceiver while driving; it is simply too dangerous. Be aware of local laws pertaining to the use of headphones/headsets while driving on public roads. If in doubt, do not wear headphones while mobiling.

Do not expose the transceiver to long periods of direct sunlight nor place it close to heating appliances.
