The S/RF meter indication, during transmit, can be se-
lected from the following items as your desired.
➥ Push [METER] several times to select the desired
item.
Indicates the relative RF output power in
watts.
Indicates the VSWR over the transmis-
sion line.
Indicates the ALC level. The ALC circuit
begins to activate when the RF output
power reaches a preset level.
Indicates the compression level when
the speech compressor is in use.
Indicates the drain's current of the final
FETs.
Indicates the drain's terminal voltage of
the final FETs.
The IC-7800 can display the multi-function digital
meter in the LCD display, which displays all transmit
meters simultaneously.
q Push [METER] for 1 sec. to turn the multi-function
digital meter ON.
w Push [F-1•P-HOLD] to toggle the peak level hold
function ON.
• "P-HOLD" appears on the window title when the peak
