Microphone R WARNING! NEVER transmit for long periods of time. During prolonged transmissions at high power or mid pow- er, the transceiver radiates heat to protect itself from over- heating. The transceiver's chassis will become hot and may cause a burn. • T o prevent the transceiver's overheating, the default set- ting of the time-out timer function is set to 5 minutes (p. 27). Be careful when the time-out timer function is turned 4 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. 38

CAUTION:
Transmitting without an antenna will damage the
transceiver.
NOTE:
To prevent interfering, hold down [SQL] to listen on
the channel before transmitting.
q
Set the operating frequency. (p. 34)
• Transmitting can be done only when the 144 MHz or 430 MHz
amateur band is selected as the MAIN band.
Hold down [LOW]
w
for 1 second to select the transmit
output power between S-Low, Low1, Low2, Mid and High
to suit your operating requirements.
• Or while holding down [LOW]
, rotate [DIAL] to select the
output power.
• No icon appears when high power is selected.
• “SLO,” “LO1,”
“LO2” or
“MID” appears when S-
low, low 1, low 2 or mid
power is selected.
Hold
down
[PTT]
to
e
transmit, and speak at
your normal voice level.
• The TX/RX indicator lights
red.
• The S/RF meter displays
the output power level.

WARNING! NEVER
transmit for long periods of time.
During prolonged transmissions at high power or mid pow-
er, the transceiver radiates heat to protect itself from over-
heating. The transceiver’s chassis will become hot and may
cause a burn.
• To prevent the transceiver’s overheating, the default set
-
ting of the time-out timer function is set to 5 minutes (p.
27). 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.
