R WARNING! NEVER transmit for long periods of time.
During prolonged transmissions at high power or middle
power, the transceiver radiates heat to protect itself from
overheating. The transceiver’s chassis will become hot and
may cause a burn.

time-out timer function is set to 5 minutes (p. 44). Be careful when
the time-out timer function is turned OFF or set to a long time
period, and you transmit for long periods.
DO NOT operate the transceiver in a situation that will ob-
struct heat dissipation, especially if the transceiver uses an
external power supply. Heat dissipation may be affected,
and it may cause a burn, warp the casing or damage the
transceiver.
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.
CONNECT to only the rated voltage range when using an
external power supply.
