Safety Instructions
In order to ensure the proper operation of the cash register, reduce the failure rate, standardize usage and
operation, and perform excellent equipment maintenance, which is helpful in extending the equipment's
service life. The following are the cash register's maintenance and maintenance best practices.
1.
The cash register should be placed in a large space with enough of heat dissipation space around it. It
should not be mixed with other sundries.
2.
A strong magnetic field is not permitted in the area of the cash register.
3.
When the cash register is running, do not move the host or make it to collide or vibrate.
4.
When reading, the hard disc cannot be suddenly shut down or turned off. You can purchase backup
power supplies if your power source is unstable or often shuts off.
5.
When the atmosphere is dry, be wary of the effects of static electricity on computer accessories. If you
come into direct contact with the computer's circuit board, please discharge yourself first (by
contacting the water pipe with your palm) or take additional precautions (such as wearing an
electrostatic ring).
6.
When the system is turned on, avoid plugging and unplugging different accessories (except those
that support hot plugging), since this may result in the burning of important chips or circuit boards.
7.
Do not use alcohol or detergent to clean the display screen. Clean water can be used if required, but
it must be adsorbed in paper or on a rag first.
8.
Do not turn on and off frequently, and the time between shutdowns should not be less than one
minute.
9.
Do not mix wire nails and other conductors into the chassis; otherwise, it is extremely possible to
make a short circuit of the board in the chassis, which can have serious consequences.
10.
To minimize lightning damage to the computer on rainy days, switch off the power of the patch
panel and unhook the power plug when shutting off the computer and not using it for an extended
period of time (Lightning damage is not covered by a free warranty).
11.
When the device is not in use for a long period of time, disconnect the power source.
12.
Wiring of any type shouldn't be exposed to air. Keep the smoothness of the wire and don't let heavy
things press against it.
13.
Corrosive liquids must not be applied to the machine's surface.
