Always finish what you are working on before disconnecting the power supply cable from
the Braille System. Switching over from the power supply to battery power takes some
time, during which fluctuations in voltage can occur.
This device must be disposed of at the end of its useful life in compliance with applicable
guidelines for electronic devices.
10.5 Handling the Braille System
The Braille System's Braille modules utilize the highly reliable and maintenance-free piezo
technology. If handled properly, you will enjoy many years of trouble-free operation.
Always operate your Braille System at normal room temperature and protect it from
humidity. Avoid exposing the Braille System to extreme changes in temperature.
Always transport your Braille System in the included carrying case, which provides impact
protection.
Do not drop your Braille System, and avoid exposing the device to strong vibrations.
Your Braille System will be the better for it if you take care to operate it with clean hands,
because otherwise the tactile pins can become sticky and may release only if prodded.
Please ensure that no fluids enter into the Braille display. The Braille elements are
especially sensitive to humidity, because humidity could destroy the high-voltage piezo
elements.
We recommend covering the Braille display whenever it is turned off, to prevent
unnecessary contamination with dust.
Clean your Braille System with a damp cloth. Do not use any cleaners. The Braille
elements must be cleaned with a dry, lintfree cloth only.
The Braille elements should be cleaned and serviced thoroughly every two years in
average operating conditions. In general, during servicing of the Braille elements, all tactile
pins and key heads will be replaced and all input elements checked. An endurance test will
then be performed. We can provide you with a replacement device during the maintenance
period.
10.6 Warranty
If you open the Braille System housing, which is sealed, within the warranty period, the
warranty becomes void. The same applies to improper handling or use.
In the unlikely event that your Braille System does become defective, our repair service
will be available for repairs.
