Power and lightning surge protection
Surge protection devices are recommended to protect the system in areas subject to lightning or power
surges. Please consult your reseller for recommended surge protection devices.
If the system has been supplied with surge protection devices to meet local regulatory requirements,
these devices must be installed as described in their installation instructions.
Do not connect or disconnect any telephone lines during thunderstorms.
Power adapter and power cord
Use only the power adapter and power cord supplied with your phone system. Check that the supply
voltage matches the rating on the power adapter label. If your supply voltage does not match the power
adapter rating, please consult your reseller.
For safe operation, the system’s power adapter must be connected to a power supply socket with a third
pin (ground /earth).
Power failure
The equipment will not operate when mains power fails.
In the event of a power failure, each phone system will connect extension E4 to phone Line 1 to permit
calls (except-AU models). Calls must be dialed without a hunt group. All other system functions will not
be available until power is restored. We recommend that a telephone that does not depend on mains
power be available for emergency use.
What happens if the power goes out or if the IP network to VoIP fails?
To ensure a reliable network connection, all elements of the VoIP network should be connected to back-up
power supplies (UPS). These elements should include LAN switches, routers, firewalls, broadband
connection devices (i.e. cable modems, DSL modems), and VoIP devices. If the power goes out at the
Internet Service Provider, no VoIP calls can be made. Calls can still be placed over the telephone lines.
External audio source isolation
We recommend that any external audio source be connected to the system using an approved Line
Isolation Unit (e.g. A-Tick (
) approved in AU).
Cleaning
Use a slightly moistened cloth or an anti-static cloth to clean the system. Do not use any solvents. Never
use a dry cloth; electrostatic charges could damage the electronics in the system. Ensure, however, that no
moisture penetrates into the system, which can result in damage.
