4.4 Working channel
A working channel will always be suggested by the system if a ship station or group is called
for a routine call. The working channel is suggested by using the following procedure:
1. Select a random channel from the list of simplex channels
2. Scan channel for traffic (open squelch)
3. If the channel is free suggest the channel.
4. If the channel is busy restart from 1.
If no channels are found to be free within 1 second no channel is suggested.

Each entry might contain:
• Station-, group-, coast station- or public name

4.5.1 Calling a contact
It is possible to initiate the following calls from the Call Contact menu item (2.1):
• Individual station (ships or coast) routine radiotelephony calls
• Group routine calls
• Direct dial phone calls to a PSTN phone
Entering the Call Contact menu item will bring up a list of possible names to select. The
name list is sorted alphabetically. The alphanumeric keypad can be used for quick search on
the first letter in the contact name (using wheel mode). Selecting a contact will show data for
the contact in question. Example:
Call Contact
Name :
Peters O il
MM S I: 00 345 6789
PSTN no : 00 45 6809876 5
When is pressed the appropriate call generator
will be initialized, based on the data.
If a PSTN number exists for the selected contact the PSTN call flow is initiated. Therefore it
is important the corresponding MMSI number for that contact being a coast station number.
If only an MMSI number is present for the contact, a ship station, group or coast station call
is initiated:
