Charging the BA 2015 accupack

To charge the accupack of the radio microphone or bodypack transmitter:

Remove the accupack as described on page 26 or page 27.

Place the accupack into the charging compartment for accupack/bodypack transmitter as shown in the diagram on the left.

The red LED CHARGE/ERROR of the charging compartment lights up.

After the accupack has been fully charged, the green LED READY lights up.

Notes:

•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:

•the accupack is deep-discharged and first has to be reconditioned by a deep discharge recovery charge,

•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.

•For safety reasons, each charging process will be interrupted after 4 hours.

•When not using the BA 2015 accupack for extended periods of time, charge it about every three to six months.
