BASIC OPERATION

Meter display

D Meter display selection

You can display one of the 6 different transmit
parameters (Po, SWR, ALC, COMP, VD and ID) for
your convenience.
Touch the parameter to display one of the meters.

D Multi-function meter

You can display all the parameters simultaneously.
L The power amplifier temperature (TEMP) meter is also
displayed on the Multi-function meter.
Hold down the parameter for 1 second to display the
Multi-function meter.

S:
Displays the receiving signal strength level.
Po: Displays the relative RF output power.
SWR: Displays the SWR of the antenna at the
operating 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.
VD: Displays the drain voltage of the final amplifier
MOS-FETs.
ID: Displays the drain current of the final amplifier
MOS-FETs.
TEMP: Displays the temperature of the final amplifier
MOS-FETs.
