Safety Precautions
Before performing an operation, read the operation instructions
and precautions to be taken, and follow them to prevent acci-
dents. The warning and danger items in other documents do not
cover all the safety precautions that must be followed. They are
only supplementary information, and the installation and mainte-
nance personnel need to understand the basic safety precautions
to be taken.
- Do not use the device in a place where wireless devices are not
allowed.
- If the device adopts power adapter supply, use a power adapter
with required specifications. Do not use the power adapter if its
plug or cord is damaged. Mains plug is used as the disconnect
device, and shall remain readily operable. The power socket
shall be installed near the device and easily accessible.
- Ensure that the input voltage is within the input range indicated
on the device.
- Do not block any ventilation openings using things such as
newspapers, table-cloth, curtains.
- Clean only with dry cloth.
- Keep the device away from water, fire, high electric field, high
magnetic field, and inflammable and explosive items.
- If such phenomena as smoke, abnormal sound or smell appear
when you use the device, immediately stop using it and discon
nect its power supply, unplug all connected cables, and contact
the after-sales service personnel.
- Disassembling or modifying the device or its accessories without
authorization voids the warranty, and might cause safety
hazards.
