Battery Replacement - Bilsom ELECTO Instrucciones Para El Usuario

14. The microphone's wind protector, which eliminates wind noise etc., should be kept clean and changed when
necessary.
15. If the above mentioned recommendations are not followed, the protection and function afforded by the earmuffs
may be severly impaired.
4. STEREO BALANCE
The sound levels of the earmuffs can be set individually using the controls B-L (left) and B-R (right) (8). Use a small
screwdriver. To access the controls, remove the ear cushion and mounting plate from the right earmuff.

5. BATTERY REPLACEMENT

Unscrew the locking screw and open the battery lid. Remove the old batteries. Insert new 1.5 V AA-alkaline
batteries into the battery compartment (1) in accordance with the instructions inside the compartment. Ensure that
the battery lid is closed completely. It is time to change the batteries when the sound reproduction is weakened or
impaired. New alkaline batteries provide approx. 130 hours operation.
6. ANTENNA
Bilsom ELECTO / ELECTO HF is equipped with a special antenna for best reception possibilities. In areas with
limited head space, it is possible to attach the antenna to the headband, but this will somewhat reduce the
reception sensitivity, especially if you are listening to a distant or weak transmitter.
7. APPROVAL
Bilsom ELECTO / ELECTO HF is tested and approved in accordance with the PPE directive 89/686/EEC, and
applicable parts of European Standard EN 352-1:2002 / EN 352-3:2002 / EN 352-4:2001.
