10.1.3.3 Add Region
The user is allowed to Add Regions, but caution is advised (see 10.1.3).
It is not allowed to delete regions, they will be deleted on timeout after 24 hours inactivity, if the ship is more than 500NM away from the region, or if the region is overwritten. There is a maximum amount of 8 regions in addition to the HIGH SEA region

button selected to get to next menu
When “Add Region” is selected, default values for Channels, Tx/Rx Mode, Power and Transition zone are configured, but all these parameters may be altered together with defining position of the North East and South West corners of the Region.

10.1.3.3.1 Change Channel
NOTE! BE AWARE THAT SETTING OF CHANNELS WITHOUT SPECIFIC KNOWLEDGE OF CORRECT SETTING MAY ALTER YOUR AND OTHER VESSELS SECURITY AS:
YOU MAY TRANSMIT ON ILLEGAL CHANNELS YOU MAY NOT BE SEEN ON OTHER VESSELS AIS OTHERS MAY NOT SEE YOU
THIS CAN IN WORST CASE LEAD TO COLLISIONS
When you select either the buttons “Channel A” or “Channel B” you may input the correct channel number.
The default channels 2087 and 2088 are the same as 87B or 88B used previously as Coast Station frequencies on 161.975 MHz and 162.025 MHz.
See complete list in Chapter 12 and for updates of this list from ITU RR, Appendix 18

10.1.3.3.2 Tx/Rx Mode
Tx/Rx Mode allows you to change setting in which the transponders will use the two regional channels for transmission (Tx) and reception (Rx)
When you press the button “Tx/Rx Mode” it will toggle between the valid configurations:
Default – will transmit/receive on both channels

10.1.3.3.4 Transition Zone
A Region must be between 20 an 200 Nautical miles and within this region there will be a “Transition zone” between 1 and 8 Nautical miles:
This zone is used for frequency transition so only one frequency is changed at a time. There are defined rules for how the AIS will behave through this zone.
The AIS will continuously monitor for its own position and range to the regional areas defined. When entering transition zone for Region 1, frequency is changed on the primary channel. The AIS is now sending the primary frequency defined for each of the regions.
When the boundary for the Region 1 is crossed, the second frequency shall be changed. Then the primary frequency for the old region (or default setting) is switched with the secondary frequency for the new region. Then both frequencies have changed.
When entering another region, frequency transition is performed as described above with the frequencies (settings) of the new region. When leaving a region, frequency transition is performed back to default values.
To change the value of this “Transition Zone”, select the button and input value between 1 and 8 (Nautical miles)

10.1.3.3.5 Define Region
A Region must be between 20 an 200 Nautical miles as described above and you must define the Longitudes and Latitudes of the South West and North East corners:
The values are defined by selecting these 4 buttons:
North East corner
South West corner
If the values are within 20 – 200 NM, they will be accepted, and you will be asked if you want to save it:
Otherwise you may experience errors:

10.1.3.5 Alarm Relay Output
The Alarm relay is a normally open earth free relay contact, provided as an independent and simple method for triggering an external alarm. The alarm relay is deactivated upon acknowledgment of an alarm, either internally on the display unit, or by an externally provided ACK sentence. If the Transponder power is lost, and the Alarm relay has power, the alarm will be triggered. In this case, the only way to deactivate the Alarm is to power the Transponder unit or disconnect the power source of the Alarm relay.
