.
● All the electrical operation should be strictly compliance with
the electrical safety regulations, fire prevention regulations and
other related regulations of the nation and region.
● To avoid fire danger caused by electrostatic charge, never touch
or wipe the device in explosive environment. Perform the
wiping and replacing accessories only under non-explosive
environment with the anti-electrostatic gloves.
● When the device is installed on wall or ceiling, it shall be firmly
fixed.
● Do not drop the device or subject it to physical shock.
● To ensure explosion-proof performance, do not damage
explosion-proof surface.
● Do not place the device in extremely hot, cold (the operating
temperature shall be -40°C to +60°C), or damp locations, and do
not expose it to high electromagnetic radiation.
● To avoid heat accumulation, good ventilation is required for
operating environment.

● To prevent accumulation of electrostatic charge, only damp
cloth can be used during the cleaning.
● While in delivery, the device shall be packed in its original
packing, or packing of the same texture.
● Regular part replacement: a few parts of the equipment shall
be replaced regularly according to their average enduring time.
The average time varies because of differences between
operating environment and using history, so regular checking is
recommended for all the users. Please contact with your dealer
for more details.
● If the product does not work properly, please contact your
dealer or the nearest service center. Never attempt to
disassemble the device yourself. (We shall not assume any
