4.3.1 Unlocking and Locking the Hand Control
The unlocking and locking of the hand control of an OS1 Mobile Operating Chair is shown here. Locking the hand
control prevents the chair from moving accidentally or unintentionally.
TIP
After removing the quick-change battery [BATTERY] and then reinserting it, the chair remains in
the previous operating status. This means, for example, that the hand control was locked before
disconnecting the battery supply, so the hand control remains locked even after the battery supply
has been restored. The control unit remembers the current operating status even without a
quick-change battery. Depending on the charging status of the quick-change battery,
the control unit changes to stand-by either after 120 minutes (charging status > 40%)
or 10 minutes (charging status < 40%). The corresponding operation control LED and the battery
indicator on the hand control switch (see Battery indicator) turns off. A chair in stand-by mode cannot
be activated by the magnetic key. Press any button on the hand control to activate. Now the chair
can be unlocked or locked.
Operating statuses
• When the chair is equipped with a quick-change battery and the hand control is disabled,
the yellow operation control LED (1) lights up.
• When the chair is equipped with a battery and the hand control is enabled with the magnetic key, the
green operation control LED (2) lights up to indicate that the chair is ready for operation.
