1.11 How to Set the Auto Acknowledgement
Individual, PSTN (public switched telephone network), position, polling and test calls
can be acknowledged automatically or manually. This is set on the [ACK SETTINGS]
in the [DSC] menu (see section 5.16).
Note: When own ship's communication is high priority, set to manual acknowledge-
ment.
The auto acknowledgement is not sent in the following cases:
• Other session is active.
• There are RT or DSC sessions (for individual call).
• Channel is in use.
• ECC is NG (No Good).
Note: The auto acknowledgement for the individual call is sent only when the pro-
posed channel or communication mode is not available.
1.12 Priority of the System
If one or more remote stations are installed, the transceiver unit has the highest prior-
ity. 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 BY: FM-8900S"
(Default. This can be changed.) is indicated on all remote stations. Each remote sta-
tion has its own priority. The remote station ID (1-4) indicates its priority. The priority
of the system is as follows.
Transceiver unit = Analog wing handset >
Digital wing handset L = Digital wing handset R > Remote station 1 >
Remote station 2 > Remote station 3 > Remote station 4
If you hook off No.4 remote station, for example, "IN USE BY: HANDSET_P4" is dis-
played on other remote stations and "HANDSET_P4: OPERATION" on the transceiv-
er unit. However, you can hook off and use No.1 remote station.
The terminal which you operate has priority in the following conditions:
• The handset goes off hook.
• Display the menus or setting windows.
• Display each function screen (for example, Log).
• Switch the session.
• Press a key or rotate the CHANNEL/ENTER knob. (The priority is lost after four sec-
onds.)
How to set the terminal ID
1. Disconnect the power plug of a remote station to turn off the remote station.
2. While pressing the MENU key of a remote station, connect the plug to turn on the
power.
3. Enter the terminal ID, using the 1 to 6 keys, then press the ENTER key. Do not
assign the same number to multiple remote stations.
4. Turn off and on the power of the transceiver unit.
