Indicates the RF output power in watts. Indicates the VSWR on the transmission 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 current of the final amplifier MOS-FETs. Indicates the drain terminal voltage of the final amplifier MOS-FETs. The IC-7800 can display the multi-function digital meter in the LCD display. This meter displays all transmit parameters 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 level hold function is ON. e Push [METER] for 1 sec., or push [EXIT/SET] to turn the multi-function digital meter OFF. 3-10
