7. Battery/rechargseable battery instructions
• Batteries/rechargeable batteries must be kept out of the reach of children.
• Do not leave batteries/rechargeable batteries lying around; they could be swallo-
wed by children or pets. If swallowed, consult a doctor immediately.
• Replace flat batteries, rechargeable batteries in time, since flat or old batteries/
rechargeable batteries may leak.
• Leaking or damaged batteries/rechargeable batteries that come in contact with
the skin can cause chemical burns, therefore use suitable protective gloves.
• Liquids leaking from batteries/rechargeable batteries are very chemically aggres-
sive. Objects or surfaces coming into contact with these liquids may be severely
damaged. Therefore, keep batteries/rechargeable batteries in a suitable location.
• Batteries/rechargeable batteries must never be short-circuited, taken apart or th-
rown into fire. There is a danger of explosion!
• Do not recharge normal, non-rechargeable batteries; there is a risk of explosion!
• Never mix normal batteries with rechargeable batteries.
• Do not mix batteries/rechargeable batteries with different charges (e.g., full batte-
ries with half-discharged batteries).
• Always replace the complete set of batteries/rechargeable batteries.
• Check that the polarity is correct when inserting the batteries/rechargeable batte-
ries (pay attention to plus/+ and minus/-).
It is possible to operate the product with rechargeable batteries. However, the operat-
ing time and the display contrast are greatly reduced due to the lower voltage (battery
= 1.5 V, rechargeable battery = 1.2 V).
We therefore recommend using only high-quality alkaline batteries instead of re-
chargeable batteries.
