11 MAINTENANCE
11.1 Monthly self-test & inspection
As an important item of safety equipment, your Precision 406 should be checked
regularly. It has a built-in test capability that can be used as a confidence check. This
self-test confirms that the battery is healthy, that the GPS receiver and both of the
distress transmitters are functional and that the strobe light is operational. The self-test
should be performed
monthly
. It should be performed during the first 5 minutes of the
hour, to minimise disturbance on the emergency channel.
If your Precision 406 is in an enclosure it can be tested through the test window
without having to remove the Precision 406 from the housing. If you have a bracket
mounted Precision 406 it will have to be removed from the bracket as described in
section 6.3. The procedure for self-testing is as follows:
• On rear of Precision 406 press and
hold
the READY button.
• The red lamp will come on for 4 seconds to confirm test in progress.
• When the red lamp goes out, the strobe lamp
must flash
3 times (at
least).
• If the strobe does not flash, or the red lamp illuminate, repeat the test
then see section 11.4.
During these monthly checks you should take the opportunity to visually inspect the
Precision 406 and its mountings for deterioration or damage.
On the Precision 406 itself check the following:
• Inspect the Precision 406 for any obvious damage.
• Check there is no sign of water inside the unit.
• Check that the lanyard is not tied to the vessel structure.
• Check the battery is within its expiry date.
If you have a wall bracket:
• Confirm the bracket top clip springs up when squeezed.
• Check the Precision 406 is correctly fitted and secure in its bracket.
If you have an enclosure:
Check the HRU is within its expiry date (category 1 only).
Confirm the cover can be manually removed with ease.
Ensure the Precision 406 base is correctly fitted into the D-shaped prongs.
If the EPIRB or its mounting needs cleaning then this should be done using warm
soapy water and a damp (not wet) cloth. Do not use strong detergents or solvents.
Do not paint the Precision 406 or its mounting
Do not clean with detergents or solvents
During vessel cleansing or painting remove the Precision 406 and its mounting.
