isolation gain processing (ISO), most of the time manual adjustments are not

required to achieve good coverage. However, in some cases where the ALC or

ISO is working at a very high rate to adjust the gain and the Alarm or ISO LED is

flashing more than once a second a manual adjustment might be desired.

once shortly and the gain value will be reduced by 1dB.

mode.
