Charging the rechargeable batteries

Charging the BA 2015 accupack

For charging, the BA 2015 accupack can remain in the
transmitter.

Place the transmitter with the accupack inserted
into the charging compartment for accupack/
transmitter

as shown in the diagram on the left.

(Alternatively, you can remove the accupack from
the transmitter and insert it into the charging
compartment on its own – both charging compart-
ments are identical and can charge the occupied
either in or out of the transmitter.)
When placed into a charging compartment, the
transmitter automatically switches off. The red LED

CHARGE

of the charging compartment lights up.

Charging a completely discharged accupack takes
approx. 3½ hours at room temperature. It is normal
for the accupacks to get hot during charging.

However, the charging process may take longer if:
y the accupack is deep-discharged and first has to be

reconditioned by a deep discharge recovery charge,

y the ambient temperature is close to or over 40 °C,

since, in order to protect the accupack, the charging
process will be interrupted until the temperature
has dropped to a safe level.

After the accupack has been fully charged, the green
LED

READY

lights up.

Notes:

y For safety reasons, each charging process will be

interrupted after 4 hours.

y When not using the BA 2015 accupack for

extended periods of time, charge it about every
three to six months.

y Only use the charging case for

charging the SK 2020 D transmitter,
the HDE 2020 D stethoset receivers
and the BA 2015 accupack.

y Never try to charge other rechargeable

batteries or non-rechargeable batteries.

Caution!
