The following power sources of the size AA, or., L6, or AM3 (Mignon) can be used:
• Alkaline: leak-proof alkaline-dry batteries
NB: alkaline batteries should not be charged or re-charged. Danger of explosion!
• Re-chargeable batteries, either nickel cadmium or nickel metal hydride. For safety reasons, to
re-charge use a charger from the original Swissphone range of accessories.
WARNING: Do not dispose of batteries and re-chargeable batteries in fire. Risk of explosion!
WARNING: Keep batteries out of reach of children under 3 years old.
The Swissphone DE920/DE940 receiver is automatically switched on when the battery is inserted.
A test is done whilst all loads in the device are activated temporarily. The device then is ready to
receive messages.
NB:
For optimal indication of the battery or re-chargeable battery levels, the type of re-chargeable
battery installed has to be set using the operation in the device (see chapter: “Selecting the type
of re-chargeable battery”).
