“P-HOLD” indicator

The IC-7700 can display the multi-function digital meter on the LCD display. This meter displays all transmit parameters simultaneously.

qPush and hold [METER] for 1 sec. to turn the multi- function digital meter ON.

wPush [F-1•P-HOLD] to toggle the peak level hold function ON.

P-HOLD” appears on the window title when the peak level hold function is ON.

ePush and hold [METER] for 1 sec., or push EXIT/SET to turn the multi-function digital meter OFF.
