6.3 Repair and modifications
The units in the AIS 200 system are not designed for customer repair. All repairs and
modifications of the units should be carried out by qualified personnel. A failed unit should
be shipped back to the supplier for repair.
6.3.1 Exchanging antenna cables
1. Disconnect the power cable.
2. Dismount the damaged antenna cable. The new antenna cable must be as straight as
possible. Do not crush or crimp the cable, as this will affect the electrical properties of
the cable.
3. Connect the antenna cable to the antenna.
4. Seale the connection between the antenna and the antenna cable against water
penetration as described in page 28.
5. Connect the antenna cable to the AIS 200 Mobile Unit and reapply power.
Note!
If the GPS antenna cable is attached to the Mobile Unit, do not attach the antenna
cable to the antenna when the AIS 200 is powered. If the antenna cable is short-
circuited with power on, the GPS receiver within the unit can be damaged.
6.3.2 Exchanging GPS or VHF antennas

cable to the antenna when the AIS 200 is powered. If the antenna cable is short-
circuited with power on, the GPS receiver within the unit can be damaged.
