Using the components
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 ³ 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.
