BASIC OPERATION

■ Transmitting

D Making a simplex call
R 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. Rotate [DIAL] to set the operating frequency.
2. Repeatedly push [H/M/L] to select an output power.
L Select a level to suit your operating requirements.
L "M" or "L" is displayed when a Mid or Low power is
selected.
L When you select High power, the power icon
disappears.
3. 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.
4. 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.
