IMPORTANT
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
competent personnel. Where the telephone faceplate is mounted into an
enclosure or recess other than the standard GAI-Tronics backbox, then
additional care must be taken that wiring and proximity to conducting surfaces
complies with the requirements of the R&TTE Directive - 1999/5/EC.
Contact GAI-Tronics if installation service is required.
From a mounting and installation point of view, VR and Help Point products
are identical.
