2.4, the default account can be taken over from the PBX if the telephone is a system
telephone and is thus set dependent on the type of exchange line request.
Note: To avoid conflicts between 3 or 4 digit phone numbers of the local area network
and the internal numbering plan, phone numbers of the local area network should
always be dialled with local area code.
Note: Also when the entered phone number correspond with the internal telephone
numbering plan, the PBX waits up to 4 seconds for whether additional digits for an
external number are being entered, before it dials the internal phone number. To avoid
waiting time, you can subsequently enter #. The PBX therefore recognises the input
as finished and instantly starts dialling.
Emergency Calls
The emergency numbers set up on the PBX are used for emergency calls. These calls are
handled in a special way.
Note: One of the basic settings is the setting of the country where the PBX is located.
By this setting the public emergency numbers of the selected country are automatically
entered in the configuration.
Emergency calls can be made without dialling an exchange line access number that is
necessary for other calls (factory setting). This has the benefit that even people who do not
know how to use exchange line access numbers can make emergency calls.
If the emergency call priority switch is enabled (factory setting), emergency calls have priority
over other calls. If necessary, a call can be interrupted to enable an emergency call to be
made.
A system telephone can also be used to make emergency calls if the screen lock is switched
on (optional, see manual of the phone).
Installation
Warning: Power surges, which can occur during electrical storms, can cause life-
threatening electric shocks and can damage or destroy the PBX.
• Do not touch the PBX or any devices connected to it during an electrical storm.
• Hire a qualified electrician to lay the cables within the building – including the cable
to the door terminal.
• Do not use the a/b ports to connect remote extensions.
Warning: Touching voltage-carrying conductors or telephone connections can cause
life-threatening electric shocks. The PBX contains hazardous voltages, even outside
the power supply unit (for instance ringer voltages). Work on active, contact-
hazardous parts is only permitted after creating a voltage-free state. Working close to
active parts is only permitted if these parts are voltage-free or are protected against
direct contact.
