D
Multi-function digital meter
The IC-7700 can display the multi-function digital
meter on the LCD display. This meter displays all
transmit parameters simultaneously.
q
Hold down [METER] for 1 second to turn the multi-
function digital meter ON.
w
Push [P-HOLD]
F-1
to toggle the peak level hold
function ON.
• “
P-HOLD
” appears on the window title when the peak
level hold function is ON.
e
Hold down [METER] for 1 second, or push
EXIT/SET
to turn the multi-function digital meter
OFF.

Meter indication selection
The S/RF meter indication, during transmit, can be
selected from the following items as you desire.
➥
Push [METER]
(MF2)
several times to select the
desired item.
METER
Po
Indicates the RF output power in watts.
METER
SWR
Indicates the VSWR on the transmission
line.
METER
ALC
Indicates the ALC level. The ALC circuit
begins to activate when the RF output
power reaches a preset level.
METER
COMP
Indicates the compression level when
the speech compressor is in use.
METER
I
D
Indicates the drain current of the final
amplifier MOSFETs.
METER
V
D
Indicates the drain terminal voltage of
the final amplifier MOSFETs.
