9. MAINTENANCE

9.1 Monthly self-test & inspection
As an important item of safety equipment, your E3 should be checked regularly. The
E3 has a built-in test capability that can be used as a confidence check. This self-
test confirms that the battery is healthy, that 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 E3 is in an enclosure it can be tested through the test window, without having
to remove the E3 from the housing. If you have a bracket mounted E3 it will have to
be removed from the bracket as described in section 4.3. The procedure for self-
testing is as follows...
• On rear of E3 press and hold the READY button for 10 seconds.
• 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).
• If the strobe does not flash repeat the test then see section 9.4.
During these monthly checks you should take the opportunity to visually inspect the
E3 and its mountings for deterioration or damage.
On the E3 itself check the following...
1) Inspect the E3 for any obvious damage.
2) Check there is no sign of water inside the unit.
3) Check that the lanyard is not tied to the vessel structure.
4) Check the battery is within its expiry date.
If you have a wall bracket...
5) Confirm the bracket top clip springs up when squeezed.
6) Check the E3 is correctly fitted and secure in its bracket.
If you have an enclosure...
7) Check the HRU is within its expiry date (category 1 only).
8) Confirm the cover can be manually removed with ease.
9) Ensure the E3 base is correctly fitted into the D-shaped prongs.
If the E3 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.
During vessel cleansing or painting remove the E3 and its mounting
Do not paint the E3 or its mounting
Do not clean with detergents or solvents
