6.5 Replacing the Batteries
Your Easy Braille has four rechargeable batteries with which you can operate
independently of a mains supply for about 10 hours. Before the device leaves the
factory, the batteries are fully charged and an insulating strip is inserted into one of
the battery compartments in order to prevent the batteries from being discharged.
After removing this strip, you can immediately use your Easy Braille without a mains
connection. When the batteries are discharged, they can be charged with the aid of
the enclosed external power supply unit.
The rechargeable batteries age in the course of time. If you use dry batteries, these
will become exhausted. In either case, the batteries must be replaced. To do this,
proceed as follows:
1. Switch off your Easy Braille and disconnect the cable of the external power
supply unit.
2. If your Easy Braille is in the carrying bag, disconnect all cables and remove
the device from the bag.
3. Turn your Easy Braille over to provide access to the bottom of the device.
4. Open the battery compartments on the bottom of the device by pushing back
the spring clips. Note that the Easy Braille has four such compartments, each
containing one battery.
5. To remove the batteries, lift the end with the notch or with the projection
(positive pole).
6. When inserting the new batteries, take care that the end with the notch
(positive pole) points away from the spring in the compartment.
7. Insert the pins on the covers into the holes in the case and press down the
other end until the spring clip snap into position.
Important notes:
Use only rechargeable NiMH batteries, since the charging circuit in the Easy
Braille is designed only for this type of battery.
If you use dry batteries instead of rechargeable batteries, always remove
these before connecting the external power supply unit to your Easy Braille.
The charging circuit cannot detect whether dry batteries or rechargeable
batteries are being used and would, if you do not remove the dry batteries,
attempt to charge them. This could cause the dry batteries to explode, causing
damage to your Easy Braille and also endangering your health.
We recommend that you replace all four rechargeable batteries at the same
time. If you replace only some of the batteries, the new batteries will age more
quickly and the partially aged batteries could be damaged. The same applies
to dry batteries.
Please dispose of exhausted batteries in accordance with the local
regulations.
