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 ³ 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.
