Distress alert transmission and output power
When the distress alert is transmitted (by pressing the DISTRESS key), the
output power of the FM-8800D/S is automatically set to maximum (25 W).
When keyboard input is prohibited
DSC-related controls cannot be operated while a DSC message is being
transmitted. (These controls are inoperative about 3 seconds during a DSC
distress call; 0.5 seconds for other DSC calls.)
1.3.3 Automatic acknowledge on/off
The automatic acknowledge feature of the DSC/watch receiver automatically
transmits the acknowledge back (ACK BQ) signal to the sending station when an
individual, position or polling call is received. (For position and polling calls,
respective item on the AUTO ACK menu must be turned on to enable automatic
acknowledge.) Automatic acknowledge can be turned on or off at the standby
display by pressing the SHIFT and 5 keys in this order.
The message AUTO ACK or MANUAL ACK appears at the bottom of the
standby display with each press of the keys.
