the rechargeable battery at the opening in the battery handle cover (part no. 10694 ri-ac-
cu® L). Now connect the power plug of the plug-in charger to the power supply. The charge
status of the battery is indicated via the LED on the plug-in charger.
Red light means charging, green light means the battery is fully charged.
3.3.3 Battery handle (2.3.3) type C with rheostat 3.5 V for charging in a 230 V or 120 V
socket.
− Remove the base of the socket handle by turning it counter-clockwise. The plug contacts
become visible. Round contacts are for 230 V mains operation (see type label), flat con-
tacts are for 120 V mains operation (see type label). Now plug the handle base into the
socket for charging.
CAUTION!
Before using the plug-in handle for the first time, it should be plugged into the socket up
to a max. of 24 hours.
Warning!
The plug-in handle must not be charged for more than 24 hours.
Warning!
The handle must never be in the socket when replacing the battery!
CAUTION!
• Should you not use the device for a long time, or take it with you while travelling, please
remove the batteries from the battery compartment.
• New batteries should be inserted when the light intensity of the instrument becomes
weaker and could impair the examination.
• In order to obtain the best possible light output, we recommend that you always replace
the batteries with 2 new, high-quality batteries (as described in 3.2.2 and 3.2.3).
Disposal:
Please note that batteries must be disposed of in a special manner. Information about this
can be obtained from your municipality or from your environmental consultant.
If there is a suspicion that liquid or condensation has penetrated the handle, it must not be
charged under any circumstances. This may cause a life-threatening electric shock, espe-
cially with plug-in handles.
3.3.4 Attaching instrument heads
Make sure that the knurled screw on the battery handle is turned up so far that the screw
tip can no longer be seen inside the holder.
Place the desired instrument head on the holder on the battery handle so that the indenta-
tion points in the direction of the knurled screw. Fix it with the locking screw.

3.3.5 Switching on and off

Switch the instrument on by pressing the red on/off switch on the black knurled plastic ring
(rheostat) and turning it to the left away from the „0". Switch off the instrument by pressing
the red on/off switch and turning it to the right to position „0".
3.3.6 Rheostat to regulate light intensity
The rheostat makes it possible to adjust the light intensity. Depending on how far you turn
the switch with the black knurled ring counter-clockwise or clockwise, the light intensity is
weaker or stronger. The marking below the rheostat serves as a guide for this.
