Charging plug
The charging plug is also suitable for bilateral amputees. It is designed such that the user can insert it into
the charging receptacle with a hand prosthesis or with their mouth.
INFORMATION
The DynamicArm can remain connected to the battery charger when the charging process is finished and
the green LED is lit. Damage to the battery caused by overcharging is not possible. Partial charging does
not decrease battery shelf life (no memory effect).
INFORMATION
The operating temparature range must be between 5 °C and 40 °C (14.0 °F and 140.0 °F).
INFORMATION
Charging is only possible at temperatures over 0 °C (32 °F). If the temperature is lower than this, char-
ging is prevented to avoid battery damage.
INFORMATION
Battery charger and AC-adapter will heat up during the charging process. This is normal.
