Preventing accidental activation
EN
To avoid accidental activation of your product, we recommend:
• When not in use, store it in a dry environment
• When not in use, make sure the knob (1) is positioned in OFF
•
In the case of obvious malfunctions, if possible remove the
batteries
In case of accidental activation
In the case of accidental activation involving transmission of AIS SART
ALERT messages, the user should deactivate the W420 MSLD and notify
the appropriate search and rescue authorities (e.g., Canadian Coast Guard
or Rescue Coordination Centre serving the geographic area) at the earliest
possible time.
Periodic checks and maintenance
Our W420 AIS MSLD does not require special maintenance, it is only
necessary to make a visual check (checking the integrity of the plastic
case) every time you proceed with a periodic test or if there is a doubt
about a possible plastic case damage and make a periodically functional
check.
There are two kinds of tests; a SHORT test that consists in checking battery
state and a LONG test that checks the operation of the GPS module. It is
recommended to carry out a SHORT test once a month, and the LONG test
is recommended on a yearly basis.
The execution of tests over the recommended schedule reduces the life
time of the batteries.
Short test (only battery)

Make sure the knob (1) is in the 'TEST' position, then press the
'Test/Activation' pushbutton (5).

Lighting of the red indicator light inside the flash lens (4) and
buzzer tone for about two seconds.
