► After contact with lubricants, promptly clean the product or parts of the product with a degreasing cleaning

INFORMATION
Regular maintenance is essential in order to retain functionality. No structural changes may be made to the sys­
tem.
INFORMATION
Converting the E-MAG Active into an E-MAG Control and vice versa may only be performed by an authorised
Ottobock Service Centre.
The battery charger may only be used in dry rooms. Regular maintenance is important and essential in order to
retain proper, safe functionality. The service life of the system can be extended by regular maintenance.
Please note that the orthosis must be inspected for functionality and signs of wear every six months, that the bear­
ing washer and bushing may need to be replaced and that the effectiveness of the locking function and electronics
must be verified (e.g. visual inspection of cable routing).
The joint connection (bushing and pin) is lubricant-free. If necessary, the joint mechanism should be protected
against dirt with suitable protective devices (e.g. joint protectors) in order to ensure proper joint functionality.
The joint and electronic components are resistant against splashed water but not waterproof!
