Error / Message Source Remedy
Bluetooth transmis-
sion distance is
less than 4 meters
(13 ft)
An obstacle in the direct line of
sight between the M 300 and the
RD 18 may reduce the transmission
distance of Bluetooth connections
down to 2 meters (6.6 ft) (particu-
larly with obstacles in the very prox-
imity of one of the instruments).
Remove the obstacle if possible.
Operate the drive unit from such a
position that you can see the front
side of the MarSurf M 300.
A relatively strong WLAN transmit-
ter or another strong transmitter
using the 2.4 GHz frequency band
is located in the very proximity of
the M 300 or the RD 18.
Remove the transmitter if possible.
ACK not received! The M 300 is attempting to set up
a Bluetooth connection with an
RD 18 and cannot establish a con-
nection.
This can happen sometimes, for
example, if the RD 18 is not yet
switched on or if it was switched
on after the M 300.
Switch on first the RD 18 and then
the M 300 and wait until the M 300
has established the connection
(sometimes this requires several at-
tempts so that the message is dis-
played repeatedly).
Battery discharged! The battery is empty. Charge the battery (approx. 7 hours
is required to charge the battery to
full capacity). When the instrument is
switched on, more time is required
for charging.
