MAINTENANCE AND TROUBLESHOOTING
6.1
HOW TO TAKE CARE OF YOUR TR20
TR20 is constructed to endure the rough maritime environment. Still the life
is dependent on taking care of the equipment. It is a good practice to regu-
larly inspect and test the equipment to detect error symptoms and prevent
more serious problems. To keep in mind during inspection:
• If 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.
6.2
REGULAR TEST PROCEDURE
It is important to perform regular testing to ensure proper operation in case
of a distress situation. If TR20 is used regularly, perform test every month.
When TR20 is stored in a lifeboat or raft, perform test at least once a year.
In order to avoid using a sealed lithium battery, we recommend keeping one
battery available for this purpose.
