6. Notes on Batteries and Rechargeable Batteries

Operation of the keyboard with rechargeable batteries is generally possible.
However, the lower voltage (rechargeable batteries = 1.2 V, batteries = 1.5 V) and the lower capa-
city of rechargeable batteries will decrease the operating time. If you want to use rechargeable
batteries anyway, use special NiMH batteries with a low self-discharge.
We recommend that you use high-quality alkaline batteries to ensure long and safe operation.
Alternatively, you can operate the keyboard via an external mains unit (not enclosed). Remove
the inserted batteries in this case.
• Keep batteries/rechargeable batteries out of the reach of children.
• Ensure that the polarity is correct when inserting the batteries/rechargeable batteries (observe plus/+
and minus/-).
• Do not leave any batteries/rechargeable batteries lying around openly. There is a risk of batteries being
swallowed by children or pets. If swallowed, consult a doctor immediately.
• Leaking or damaged batteries/rechargeable batteries can cause chemical burns to skin on contact; the-
refore, use suitable protective gloves.
• Liquids leaking from batteries/rechargeable batteries are chemically highly aggressive. Objects or sur-
faces that come into contact with them may take severe damage. Therefore, keep batteries/rechargeab-
le batteries in a suitable location.
• Make sure that batteries/rechargeable batteries are not short-circuited, disassembled or thrown into
fire. There is a danger of explosion!
• Do not recharge normal, non-rechargeable batteries. There is a danger of explosion! Only charge re-
chargeable batteries which are intended for this purpose; use a suitable battery charger.
• If not used for a longer period (e.g. in case of storage), remove the inserted batteries/rechargeable
batteries. There is a danger of old batteries/rechargeable batteries leaking, which causes damage to the
product, loss of warranty/guarantee!
• Always replace the entire set of batteries/rechargeable batteries, only use batteries/rechargeable bat-
teries of the same type and by the same manufacturer with the same charge status (do not mix charged
with partially charged or empty batteries/rechargeable batteries).
• Never mix batteries and rechargeable batteries. Use either batteries or rechargeable batteries.
• For proper disposal of batteries and rechargeable batteries, please read the chapter „Disposal".
