Battery Handles And Commissioning; Purpose; Operational Readiness; Caution - Riester e-scope Gebrauchsanweisung

2. Battery handles and commissioning

2.1. Purpose

The Riester battery handles described in this manual are used to power the instru-
ment heads (the lamps are incorporated into the corresponding instrument heads).
They also serve as a holder.

2.2. Operational readiness

(Inserting and removing Batteries)
Turn the instrument head anticlockwise to remove it from the handle. Insert 2 stan-
dard AA (Mignon) 1.5 V alkaline batteries (IEC standard designation LR6) into the
handle sleeve so that the positive terminals point towards the upper part of the handle.

2.3. CAUTION:

• If you do not use the device for a long time or take it with you while travelling,
please remove the batteries from the handle.
• New batteries should be inserted when the light intensity of the instrument beco-
mes weaker and could impair the examination.
• For optimal light output, we recommend that you always use new high-quality
batteries when changing the battery.
• Make sure that no liquid or moisture penetrates the handle.

2.4. Disposal:

Please note that batteries must be disposed of specially. Information about this can be
obtained from your municipality or from your responsible environmental consultant.
Attaching instrument heads
Twist the instrument head clockwise onto the handle.
Switching on and off
There is an on/off slide switch on the handle. If the slide switch is pushed up, the
device is switched on; if it is pushed down, the device is switched off.
