sequentially-switched LEDs indicates the state of charge of the Li-ion battery. The state of charge is
shown whether an instrument is connected or not.
All four LEDs illuminated indicated a fully-charged battery,
If only the yellow LED illuminated, the battery must be recharged. Switch off the battery and recharge it
by means of the transformer.
Caution: Please use the appropriate battery. The battery should never be placed in municipal
waste. Please check local regulations for disposal of batteries.

if the battery is used in high or low temperatures, the battery capacity will be reduced.
The old batteries should never be placed in municipal waste.
3.3 Cleaning and sterilization
•
The outer surface of the instrument may be cleaned with wet cloth, the remaining stains can be
