3.3 Charging the Battery
The MarSurf M 300 and the MarSurf RD 18 are
powered by a built­in battery.
Both instruments can be supplied with
electricity for stationary operation by
con necting the AC adapter that came
with delivery to the MarSurf M 300 and
creat ing a cable connection between the
two instruments (see below).
The batteries of both instruments should be
charged
if the instrument is being commissioned for −
the first time,
if around 3 months have passed since the −
battery was last charged,
if the symbol − is displayed in the top sta­
tus bar (i. e. the battery is down to around
15 % of its capacity),
if no meas urement is possible, even though −
the symbol is not yet displayed.
11
For charging, only use the AC adapter
that came with delivery!
If other AC adapters are used, the
MarSurf M 300 or RD 18 may be dam­
aged and any warranty will be rendered
null and void.
To prepare the AC adapter:
1. Select the appropriate mains adapter and
insert it into the AC adapter.
11 This can happen after long periods of storage, for exam­
ple.
