Use of W840 charger module
To use the W840 device:
•
put the W840 device close to the radio-buoy that needs to be
recharged and lay it on the three contact elements (see W800 /
W810 radio-buoy instructions)
•
Take action on the wing nut (3) and turn the screw clockwise. Do
not close the screw all the way down but leave it in a light tension
thanks to the spring retainer.
•
The W840 equipment will begin charging the battery and it will
end automatically after 6 hours.
•
During the charging phase, it is possible to monitor the charging
process through the two indicator lights (1) and (2) according to
