Selecting Output Power
It's wise, and required by law, to select the lowest power
that allows reliable communication. If operating from
battery power, lower transmit power will give you more
operating time before a charge is necessary. Reducing
power lowers the risk of interfering with others on the
band.
Press [LOW] to select the transmit power you require.

(No Indicator)
CAUTION:
DO NOT TRANSMIT WITH HIGH OUTPUT POWER FOR
EXTENDED PERIODS. THE TRANSCEIVER MAY OVERHEAT
AND MALFUNCTION.
CONTINUOUS TRANSMISSIONS CAUSE THE RADIATOR TO
OVERHEAT. NEVER TOUCH THE RADIATOR IN SUCH A
SITUATION.
Note: When the transceiver overheats because of ambient high
temperature or continuous transmissions, the protective circuit may
function to lower transmit output power.
