Maintenance and Troubleshooting
Safety Reminders
Carefully follow these safety requirements before servicing the keyboards.
•
The keyboard does not contain any user serviceable parts and should only be
serviced by a qualified service technician.
•
Before servicing the keyboard, plug your ground strap into a proper grounding
outlet. Failure to do so may damage it. Also, disconnect the power cord from the
POS terminal to which the keyboard is connected and disconnect the cables from
the POS terminal to the keyboard.
•
To protect the internal circuitry from damage, unplug the power cord and then
momentarily press the power switch to drain the power supply capacitance.
•
The power cord is used as the main disconnect device. Ensure that the socket outlet
is located or installed near the equipment and is easily accessible.
•
The keyboard should only be powered by a Safety Extra Low Voltage (SELV) power
supply source with an available power level of 5 amperes or less, and suitable for the
country of installation. The power source must be certified by the appropriate safety
agency for the country of installation.
•
If the peripheral does not have a fuse, it must be powered by an SELV power
supply source.
•
If the peripheral has a fuse, replace only with the same type and ratings of fuse for
continued protection against risk of fire.
