Using the charger

Charging the rechargeable battery BA 2015

 Insert the rechargeable battery  into one of the two charging

compartments  as shown.

The red LED  at the occupied charging compartment lights up.

Charging a completely discharged rechargeable battery takes

approx. 2½ hours at room temperature. It is normal for the

accupacks to get warm during charging.

However, the charging process may take longer if:

y the rechargeable battery 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 rechargeable battery temperature has

fallen to an admissible value.

For safety reasons, the charging process will be interrupted and

the red LED  will start flashing if:

y excessively hot accupacks cannot cool down,

y an rechargeable battery cannot be fully charged within the

max. charging time of 6 hours, e.g. due to overaged cells.

 After the rechargeable battery has been fully charged, the green

LED  lights up.

Note:

For charging, the accupacks can remain in the unit. Place the

unit  with the rechargeable battery inserted into the charging

compartment  as shown. The receiver or the transmitter auto-

matically switch off.

Care and maintenance

Use a slightly damp cloth to clean the switched-off charger from

time to time. Use a brush or similar to remove dust from the

charging compartments. Do not use any cleansing agents or

solvents.
