WARNING! NEVER
transmit for long periods of time. During prolonged
transmissions at high power 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.
1. Select the operating mode. (p. 15)
2. Rotate [DIAL] to set the operating frequency. (p. 16)
3. Hold down [LO] for 1 second to select an output
power.
•The Select Output Power window is displayed.

Information
•You can select S-Low, Low1, Low2, Mid, or High.
•You can also select an output power by rotating [DIAL]
while holding down [LO].
•When you select a high power, the power icon
disappears.
•Select a level to suit your operating requirements.
4. Hold down [PTT] to transmit, and speak into the
microphone at your normal voice level.
•The TX/RX indicator lights red.
•The S/RF meter displays the output power level.
5. Release [PTT] to receive.
TIP: To maximize the readability of your signal
1. After pushing [PTT], pause briefly before you start
speaking.
2. Hold the microphone 5 to 10 cm (2 to 4 inches) from
your mouth, then speak at your normal voice level.
