BASIC OPERATION
■ Transmitting
D Making a simplex call
R WARNING! NEVER transmit for long periods of time. During prolonged
transmissions at high or mid-power, the transceiver radiates heat to protect itself from
overheating. The transceiver's chassis will become hot and may cause a burn.
To prevent the transceiver's overheating, the default setting of the time-out timer
function is set to 5 minutes. Be careful when the time-out timer function is turned OFF
or set to a long time period, and you transmit for long periods.
CAUTION: DO NOT operate the transceiver where heat dissipation will be obstructed
if the transceiver is also being charged with an external power supply. Poor heat
dissipation may cause a burn, warp the casing, or damage the transceiver.
CAUTION: DO NOT transmit without an antenna.
NOTE: When the transceiver becomes hot, the transceiver's heat protection function
gradually reduces the output power to approximately 2.5 watts, then it stops transmission
after that. This is done to protect the transceiver itself until it can cool down.
NOTE: You can transmit on only the amateur frequency bands.
IMPORTANT: Before transmitting, monitor the operating frequency to make sure
transmitting won't cause interference to other stations on the same frequency.
