4-3 Periodical cleaning of conductive switch terminal
(1) Importance of periodical cleaning
This Satellite EPIRB transmits distress signal after detecting water when it is activated by automatic
release.
Although the Satellite EPIRB is stored in a case (automatic release bracket), small dust may invades into
the case and adhere on the conductive switch terminal as the automatic release bracket is not water-tight
structure. The Satellite EPIRB may not be activated properly when oily dust adhered on its conductive
switch terminal.
The Satellite EPIRB may not transmit the distress signal even if it is on the water when the
conductive switch terminal is smeared by oily dust. Perform periodical cleaning of the Satellite
EPIRB in accordance with the procedure described below.
The distress signal may transmit by removing the Satellite EPIRB main unit from the automatic
release bracket when the conductive switch terminals are covered by wet salt. Perform periodical
cleaning of the Satellite EPIRB in accordance with the procedure described below.
(2) Cleaning procedure
The conductive switch terminal and its surrounding, and the side of Satellite EPIRB main unit should
always be kept clean so that the Satellite EPIRB can be activated properly. Please perform following
periodical cleaning about once a month.
1) Confirm that the Satellite EPIRB main unit is not wet, and the selector switch is set to “READY”.
2) Remove the Satellite EPIRB main unit from the automatic release bracket.
3) Wipe the side of Satellite EPIRB main unit carefully by using soft cloth wet with the fresh water and
squeezed hard. Be sure to wipe the two conductive switch terminal one by one.
If the Satellite EPIRB starts to transmit the distress signal during the cleaning by any mistake,
re-install the Satellite EPIRB main unit to the automatic release bracket immediately (within 50 sec.
after transmission started) to stop the transmission.
