BMW On-Board Computer Wartungshandbuch PDF herunterladen (Seite 140)

If the battery is not discon-

nected, the on-board elec-

tronics (e.g. clock, etc.) gradually

drain the battery. This can cause

the battery to run flat. If this hap-

pens, warranty claims will not be

accepted.

Connect a float charger to the

battery if the motorcycle is to

remain out of use for more than

four weeks.

BMW Motorrad has de-

veloped a float charger spe-

cially designed for compatibility

with the electronics of your mo-

torcycle. Using this charger, you

can keep the battery charged

during long periods of disuse,

without having to disconnect the

battery from the motorcycle's

on-board systems. You can ob-

tain additional information from

your authorised BMW Motorrad

dealer.

Charging battery when

connected

Charging the connected

battery directly at the bat-

tery terminals can damage the

vehicle electronics.

Always disconnect the battery

from the on-board circuits be-

fore recharging it with a charger

connected directly to the battery

posts.

If you switch on the igni-

tion and the multifunction

display and indicator lights fail

to light up, the battery is com-

pletely flat (battery voltage is less

than 9 V). Attempting to charge

a completely flat battery via the

extra socket can cause damage

to the motorcycle's electronics.

If a battery has discharged to the

extent that it is completely flat, it

has to be disconnected from the

on-board circuits and charged

with the charger connected dir-

ectly to the battery posts.

Only chargers suitable for

this mode of charging can

be used to recharge the battery

via the on-board socket. Unsuit-

able chargers could cause dam-

age to the motorcycle's on-board

electrics.

Use BMW suitable chargers. A

suitable charger is available from

BMW Motorrad your authorised

dealer.

Charge via the power socket,

with the battery connected

to the motorcycle's on-board

electrical system.

The motorcycle's on-board

electronics know when the

battery is fully charged. The

on-board socket is switched off

when this happens.

Comply with the operating in-

structions of the charger.
