The automatic acknowledge feature, when turned on, automatically transmits the acknowledge

position and polling calls, respective item on the AUTO ACK menu must be turned on to enable
automatic acknowledge.) It can be turned on or off at the DSC standby screen by pressing the
[5/ACK] key. The message AUTO ACK or MANUAL ACK appears at the top-right corner of the
DSC standby screen with each press of the key.
