3.3. Ending the Call
There is no direct way for a user to end a call from the unit. The unit will close
down and release the line on receipt of the following signals, usually when the
remote party clears:
•
Line polarity reversal
•
A line break (sometimes referred to as a "k break").
•
Receipt of exchange call progress tones (see section 9 for specification)
3.4. Call timer
The phone has a programmable call timer that can limit the maximum call
duration.
When ON, the timer forces the phone back off line after the preset time. This
prevents the line remaining tied if the neither party ends the call. The timer is
factory-set to 7mins by default, but can be set to any value (up to 2¾hrs) or
disabled. See section 7.2.1.

Installation
5.1. General
All possible measures must be taken to ensure water, fluid or dust
does not contaminate the internal components of the telephone whilst
unpacking, preparing and installing the telephone in inclement weather
conditions or by negligence.
Failure to do so may invalidate your warranty.
These telephones are supplied without connection leads – cabling to the
telephone network must be supplied and installed by the installer. Because of
this, extra precautions must be observed: installers must ensure that they
have the permission of the owner of the PABX or telephone network to which
the telephone is to be connected, and that installation is carried out by
