Setting up the charger The charger has four plastic feet to ensure that it cannot slip on the surface on which it is placed. Attention! Some furniture surfaces have been treated with varnish, polish or synthetics which might cause stains when they come into contact with other synthetics. Despite a thorough testing of the synthetics used by us, we cannot rule out the possibility of staining.

Charging a completely discharged accupack takes approx. 2½ hours at room temperature. It is normal for the accupacks to get warm during charging.
왘 After the accupack has been fully charged, the green LED lights up. Note: For charging, the accupacks can remain in the bodyback transmitter (SK) or receiver (EK). Place the unit with the accupack inserted into the charging compartment as shown. When placed into the charger, the EK/SK automatically switches off (except for EK 300 IEM).
If problems occur... If a red LED starts flashing, one of the following errors has occurred at the corresponding charging compartment: ! No contact with the accupack (contacts are dirty or accupack is not inserted correctly): Clean the contacts or insert the accupack correctly. ! Accupack is defective (overaged or defective rechargeable battery cells): Replace the accupack. ! Accupack temperature is too low or too high: Always charge the accupack at room temperature.
