6. Information Relevant to Batteries
and Rechargeable Batteries
• Batteries must be kept out of the reach of children.
• Do not let batteries/rechargeable batteries lie around openly. There is a risk of batteries
being swallowed by children or pets. In such a case, seek instant medical attention!
• Batteries/rechargeable batteries must never be short-circuited, taken apart or thrown into
fire. There is a risk of explosion!
• Leaking or damaged batteries/rechargeable batteries may cause acid burns when coming
into contact with skin, therefore use suitable protective gloves.
• Do not recharge normal batteries. There is a risk of fire and explosion!
• Please observe the correct polarity (positive/+ and negative/-) when inserting the batteries/
rechargeable batteries.
• If the device is not used for a longer period of time (e.g. storage), take out the inserted
batteries/rechargeable batteries to avoid damage from leaking batteries/rechargeable
batteries.
• Always replace the whole set of batteries/rechargeable batteries. Do not mix full batteries/
rechargeable batteries with half-full ones Always use batteries/rechargeable batteries of the
same type and from the same manufacturer. Never mix disposable batteries with rechargeable
batteries.
Operation with rechargeable batteries (instead of disposable batteries) is also
possible. However, due to the lower voltage of rechargeable batteries (disposable
batteries = 1.5V, rechargeable batteries = 1.2V), the operating time can be
shorter. In addition, rechargeable batteries are more temperature sensitive (e.g.
when operating in winter); furthermore NiMH rechargeable batteries have a high
self-discharge rate depending on the type.
Therefore, we recommend that you only use high-quality alkaline batteries in
order to ensure long-lasting and reliable operation of the "FS20 UTS".
