10.4 General Safety Information
Avoid contact between your Braille System and any fluids (rain, coffee...). If fluids enter
into the housing, you may be exposed to the danger of hazardous electric shock. In
addition, the Braille elements may sustain damage, which can only be remedied by costly
repairs.
Only representatives of Handy Tech Elektronik GmbH or its authorized dealers have
permission to open the Braille System. The device contains no user-serviceable parts. In
the event of a defect, please contact your dealer, or Handy Tech directly. Only an
authorized Handy Tech dealer has permission to service the device.
Avoid switching your Braille System on immediately after moving it from a cold room into a
warm environment. Under unfavorable conditions, condensation might ruin the device.
Wait until the device has warmed to room temperature before turning it on.
Do not expose your Braille System to extreme temperature fluctuations or high humidity
during operation. The operating temperature should be between +10°C (= 50°F) and
+40°C (= 100°F) and relative humidity may not exceed 80%.
The Braille System must not be operated in moist rooms, for example, bathrooms,
because the device generates voltages up to 200 V.
All cables (interface cable, power cable) must be installed such that they do not pose any
hazards (tripping hazard).
Whenever you want to connect or disconnect the interface cable to or from the Braille
System, always avoid any direct touching of the wire contacts in the plug. Touching the
contacts could damage your computer interface through static electricity overload.
Before disconnecting the interface cable from the Braille System, we recommend first
disconnecting the cable from the PC.
Please use only the power supply unit (type FW7555M/09) and cable supplied with your
Braille System for connecting it to utility power and for recharging the batteries. Never use
the included power supply if the Braille System contains commercial non-rechargeable or
nickel cadmium-batteries.
When cleaning the device, always disconnect both the power cable and the interface
cable.
If the Braille System was dropped, the housing has become damaged, or the Braille
System is malfunctioning, turn the unit off immediately. It needs to be serviced by
authorized service personnel.
The power supply should be disconnected if the unit will not be used for an extended
period of time.
