Installation
•
The DTR is a ringdown telephone that utilizes the features of the PABX to route
calls to the desired location.
•
Follow all appropriate electrical codes and use only approved electrical fittings for
the installation.
•
If required install primary surge protection external to the telephone.
•
The telephone may be installed on a flat surface or wall mounted.
•
Ensure that none of the electrical connection circuits are live by disconnecting the
Tip and Ring conductors at the demarcation block or PABX.
•
If the built in Ring Detect Relay is to be utilized to activate an external alarm,
ensure that the power conductors are not live.
•
Using the 3mm Allen Key provided loosen the four faceplate captive screws to
detach the faceplate from the base.
Desk Top Configuration
•
If the telephone is to be desktop mounted set the base in the desired location.
Wall Mount Configuration

If the telephone is to be wall mounted choose a location that is free of
obstructions and permits space for wiring. Mount the base with the deepest
dimension on the bottom. Mount as follows:

o
The telephone weighs 3.95 kilograms (8.68 pounds), ensure that the
mounting can support four times the weight of the unit; that is 15.8
