BASIC OPERATION
Meter display
D
Meter display selection
You can display one of the 6 different transmit
parameters (Po, SWR, ALC, COMP, V d , and I d )
for your convenience.
Touch the parameter to display one of the meters.
When the V d meter reads
on the red under line or
below, the output power may
decrease, or transceiver
power may be shut down.
Displays the
temperature of the final
amplifier MOS-FETs.

Adjusting the transmit output
power
Before transmitting, monitor your selected
operating frequency to make sure you do not cause
interference to other stations on the same frequency.
It is good amateur practice to listen first, and then,
even if nothing is heard, ask if the frequency in use
once or twice, before you start operating.
1. Select the operating mode. (p. 3-2)
(Example: RTTY)
2. Touch the meter to display the Po meter.
( p. 3-9 )
3. Push to open the Multi-function menu.
4. Hold down [PTT].
• The TX/RX indicator lights red, and is
displayed.
• The Po meter level changes according to your
voice level in the SSB mode. It becomes the
S-meter while receiving.
5. Touch [RF POWER], and rotate to
adjust the transmit output power between 0
and 100% (in 1% steps).
L
In the AM mode, the maximum transmit output
power is a quarter of the other mode’s output.
L
The transmit output power is limited to the
maximum transmit output power.
6. Release [PTT].
• Returns to receive.
S: Displays the receiving signal strength level.
Po:
Displays the relative RF output power.
SWR: Displays the SWR of the antenna at the
frequency.
ALC: Displays the ALC level. When the meter
movement shows the input signal level
exceeds the allowed level, the ALC limits
the RF power. In such cases, decrease the
microphone gain level.
COMP: Displays the compression level when the
speech compressor is used.
V d : Displays the drain voltage of the final
amplifier MOS-FETs.
I d :
Displays the drain current of the final
amplifier MOS-FETs.
TEMP: Displays the temperature of the final
amplifier MOS-FETs.
The selected
meter’s icon is
displayed.
D
Multi-function meter
You can simultaneously display all the
parameters.
L
The TEMP meter is also displayed on the Multi-
function meter.
Touch the currently displayed parameter for 1
second to display the Multi-function meter.
“Po” is displayed.
