3012—Fault finding
308 NGT Transceiver System Technical Service Manual
Adjustments and routine maintenance
The data modem has been designed so that no routine adjustments or maintenance are
required.
A newly commissioned data modem should not require testing as all units have passed a
detailed and extensive test procedure at Codan before being despatched.
The data modem is not field serviceable. If a fault is identified, it should be returned to
your Codan representative for repair.
