Distress alert transmission and output power
When the distress alert is transmitted (by pressing the DISTRESS key), the
output power of the FM-8800D/8800S 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 or polling call is received. (For 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 with each press of the
keys.
Note 1: To give priority to own ship's communications while own ship is
communicating, show MANUAL ACK by the above procedure.
Note 2: Automatic acknowledge is not possible under the following conditions:
Priority: Distress, Urgency or Safety
Com Type: Fax, Data, No Info
Com Freq: No Info
Off Hook
1.4 Priority
If one or more remote stations are installed, the transceiver unit (main unit) has
the highest priority. You can interrupt remote station operation at any time with
the handset of the main unit. When you hook off the handset of the main unit,
“OCCUPIED FM8800” (default. This may be change. See section 5.3) is
indicated on all remote stations.
Each remote station has its own priority. The remote station ID (1-4) indicates its
priority. The priority of the system is as follows.
DSC of main unit
> Wing handset > Handset of main unit > 1 > 2 > 3 > 4
If you hook off No.4 remote station, for example, “Occupied Handset4” is
displayed on other remote stations. However, you can hook off and use No.1
handset.
Note: The priority is disabled at the distress mode.
