Power Failure; What Happens If The Power Goes Out Or If The Ip Network To Voip Fails; External Audio Source Isolation; Cleaning - Fortinet FortiVoice FVC Series Hardware Manual

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 and the FVC-40S). 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.
Powered line phones may lose memory or key settings in the event of a power failure.

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

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 (

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 gets into the system.
