5.2 Warning signals, use of 17B203 electronics
5.2.1 Battery charge level
INFORMATION
The electronics will turn off if the battery is discharged completely. The lock can be released manually.
Should the battery charge level fall below the preset charge capacity, the electronics will emit the warning signals
listed here:

Battery low
Battery empty
The warning signal is repeated every 15 minutes. Replacing the battery immediately is highly recommended. How
quickly the battery is discharged depends on the ambient temperature: The colder it is, the faster the battery will be
drained. The electronics will turn off if the battery power is insufficient. If this occurs, the orthotic knee joint can
only be unlocked manually (see fig. 4).
5.2.2 Failure of the electronics
The E-MAG Active is not vulnerable to failure. However, should disruptions occur, the electronics recognise the
failure and send a warning signal.

6 Cleaning
1) Keep your orthosis away from damp environments. Use a slightly moistened cloth to wipe the orthosis, E-MAG
Active or any of the components clean from outside.
2) Due to the construction of the orthotic knee joint, clothing fibres cannot get into the mechanics. However,
please observe the six-month maintenance intervals, because fine dust can settle in the electronics and mech­
anism, which can lead to malfunctions of the E-MAG Active.
7 Maintenance
Have your O&P professional check your E-MAG Active for wear and tear as well as proper functioning of the elec­
tronic components every six months.
