When driving the screws into the wall, be careful to avoid touching any
metal laths, wire laths or metal plates in the wall.
When this unit is no longer in use, make sure to detach it from the wall.
CAUTION
Keep the unit away from heating appliances and devices that generate
electrical noise, such as fluorescent lamps, motors and televisions. These
noise sources can interfere with the performance of the unit. It also should
not be placed in rooms where the temperature is less than 0 ºC or greater
than 40 ºC.
Wipe the unit with a soft cloth. Do not clean the unit with abrasive
powders or with chemical agents such as benzine or thinner.
The handset hook poses a choking hazard. Keep the handset hook out of
reach of children.
When left unused for a long period of time, disconnect the unit from
the AC outlet. When the unit receives power from a PoE power supply,
disconnect the Ethernet cables.
When the unit is mounted on a wall, make sure the cables are securely
fastened to the wall.
Notice
• If the unit does not operate properly, disconnect the AC adaptor cord and
Ethernet cables and then connect again.
• If you are having problems making calls, disconnect the Ethernet cables
and connect a known working SIP Phone. If the known working SIP Phone
operates properly, have the defective SIP Phone repaired by an authorised
service centre. If the known working SIP Phone does not operate properly,
check the SIP server and the Ethernet cables.
• Under power failure conditions, the SIP Phone may not operate. Please
ensure that a separate telephone, not dependent on local power, is available
for use in remote sites in case of emergency.
