6.2 REGULAR TEST PROCEDURE
It is important to perform regular testing to ensure proper operation in case of a distress
situation. If Tron TR20 is used regularly, perform test every month. When Tron TR20 is
stored in a lifeboat or raft, perform test at least once a year. In order to avoid using a sea-
led lithium battery, we recommend keeping one battery available for this purpose.
Regular test procedure:
Step Item Description
1 Housing Check the housing for mechanical defects and
and keys check that all keys are in good working order.
2 Battery Check the battery status indicator and charge or
change battery if needed.
3 Transmit Check that the Tx indicator is visible when
transmitting. The Tx indicator indicates that carrier
is produced at the antenna output.
4 Communications Communicate with another radio-telephone to
test test receive and transmit functions.
6.3 CLEANING OF DIRT AND OIL
To clean away oil and dirt from the radio, use ordinary dish-soap and water.
The water temperature can be up to 45°C. Finish of by rinsing with fresh water.
6 MAINTENANCE
6.1 HOW TO TAKE CARE OF YOUR TRON TR20
Tron TR20 is constructed to endure the rough maritime environment. Still the life is depen-
dent on taking care of the equipment. It is a good practice to regularly inspect and test the
equipment to detect error symptoms and prevent more serious problems.
To keep in mind during inspection:
• If Tron TR20 has been immersed into seawater, it is good practice to clean it in fresh water.
• Inspect battery connection pins, the gasket and the locking/release device.
• Inspect the housing for defects, which can affect the water sealing.
