Due to aging of the batteries, or if you have been using non-rechargeable batteries, the
batteries must be replaced periodically. Please proceed as follows to replace the batteries:
1. Turn off the Braille System and disconnect the power supply cable.
2. If the Braille System is inside of its carrying case, disconnect all cables connected
to the device and take it out of the case.
3. Turn the device over horizontally, so that the control keys are underneath.
4. The battery compartments on the bottom of the housing are secured by snap
catches, which should be pushed towards the batteries in order to open the cover.
Please note that the Braille Star 40 features a compartment for 4 batteries, the
Braille Wave two compartments for 2 batteries each, and the Braillino four
compartments with one battery each.
5. Now you can remove the batteries by lifting them out by the plus side, which has
the indent.
6. When inserting the new batteries, make sure that the buttons on the top, which
includes an indent (plus pole), point away from the springs contained in the battery
compartments.
7. You lock the covers again by inserting their pins into the appropriate recesses on
the housing and then pushing down lightly on the catches. The catches snap
audibly into place.
8. You may now return the Braille System to its carrying case and close the snaps.
Important Notes:
1. Please use only NiMH batteries, as the Braille System's recharging circuitry has
been designed for that type of battery only.
2. If you replace the rechargeable batteries with standard non-rechargeable batteries,
you must make sure that you remove these before connecting the Braille System to
a power outlet, because the recharging circuitry cannot discern the difference. The
batteries would therefore be overcharged (danger of explosion), which may cause
damage to your Braille System, and in certain cases may be hazardous to your
health.
3. We do not recommend replacing only some of the batteries. If batteries are only
replaced partially, the new cells will be used up more rapidly and cells with a lower
capacity may be damaged. The same applies if you are using non-rechargeable
batteries.
4. Please refer to the applying environmental law for disposal of batteries.
