FUNCTIONS FOR RECEIVE

5

The AGC (auto gain control) controls receiver gain to produce a constant audio output level even when the received signal strength varies greatly.

The transceiver has 3 preset AGC characteristics (time constant: fast, mid, slow) for non-FM mode.

The FM mode AGC time constant is fixed as ‘FAST’ (0.1 sec.) and AGC time constant cannot be changed.

qSelect any non-FM mode.

wPush [AGC] (MF5) several times to select AGC fast,

AGC medium (MID) or AGC slow.

• Push and hold AGC VR for 1 sec. to turn the AGC function OFF.

qSelect any non-FM mode.

wPush AGC VR , then rotate [AGC] control to adjust the AGC time constant.

• [AGC VR] indicator above the switch lights green.
