any other wireless devices.
• On devices with intercom or built-in speaker
or built-in microphone or signal transmission
functions, keep the wires more than 30 cm
(12'') away from AC 100-240 V wiring. AC
induced noise and/or device malfunction
could result.

accessible for future inspections, repairs and
maintenance.

the device may malfunction.
• The device can be damaged if dropped.
Handle with care.
• The device turns inoperative during power
failure.
• On devices with intercom or built-in speaker
or built-in microphone, in areas where cellular
or Radio / TV broadcasting station antennas
are close by, the device may be affected by
radio frequency interference.
• On devices with LCD screen, it must be noted
in advance that the LCD panel, though
manufactured with very high precision
techniques, inevitably will have a very small
portion of its picture elements always lit or
not lit at all. This is not considered a device
malfunction.
• On devices with intercom, due to the
environmental sound around the device, it
may hinder smooth communication, but
this is not a malfunction.
• On devices with Username/Password, the
Username/Password to access the device is
4
the customer's responsibility. Make sure to
use a password that cannot be easily guessed
by a third party. We recommend that you
change the Password on a regular basis.
• We will, under no circumstances, be liable
for damage that occurs due to failures in
power supply, network equipment or terminal
devices; failures due to Internet providers
and cellular network providers; failures such
as disconnected lines and other losses in
communication, which makes it impossible to
provide this service as well as in any way delay
this service due to any other causes outside of
our responsibility; or if an error or missing data
occurs during transmission.
