Recharging the batteries
CAUTION
Never use battery chargers to charge non-rechargeable batteries. Never open rechargeable
batteries or throw them into fire. Used (defective) rechargeable batteries are subject to special
waste disposal. Do not put them in the household refuse !
Use a CeoTronics charger (see section 11) to
charge the 3.6 V/600 mAh battery in the headset.
Using other chargers can cause rechargeable
batteries to become damaged. The charging time
of a battery is dependent on the charger you are
using. Separate CeoTronics operating instructions
are available for this purpose.
The battery charging socket (Fig. 5/b) is located
on the right-hand headset muff and is sealed with
a stopper (Fig. 5/a). Before connecting the
charger pull the stopper out of the battery
charging socket and re-insert it after recharging.
WARNING
To recharge the battery always switch off the headset (On/Off switch and volume control in
position »OFF«).

Maintenance
10.1 Visual inspection
Regularly examine the headset muffs and in particular the ear cushions for signs of fractures, cracks
and wear. If the headset muffs are damaged, replace them and send them in to CeoTronics for repair.
Replace damaged or worn ear cushions in accordance with section 10.4, and, even if not damaged,
every 6 months of use at the latest.
10.2 Cleaning
WARNING
When cleaning ensure that no moisture penetrates inside the unit. Do not use any solvents
(e.g. benzine, alcohol, etc.) for cleaning purposes !
Remove any loose dust with a soft brush. Clean, if necessary, the outside with a suitable clean cloth
that has been slightly moistened with clear water, and rub the parts dry afterwards. If heavily soiled,
some dishwashing liquid can be used in addition.
