SECTION 5  WALL INSTALLATION
5.1 Mounting the Base Directly to the Wall
Before mounting the telephone, consider the following:  
Select a location away from electrical cables, pipes, or other items behind the 
mounting location that could cause a hazard when inserting screws into the 
wall.
The location must be near a 120Vac power outlet so that the AC power adapter 
can reach.
Also consider proximity to the PBX (key system) so that the telephone line cord 
will not be excessively long.
Make sure the wall material is capable of supporting the weight of the base unit.
Use #10 screws with anchoring devices suitable for the wall material where the 
base unit will be placed.
To mount the telephone:
1. Insert two mounting screws 3-15/16” apart.  Allow 3/16” between the 
wall and screw heads for mounting the telephone.
  
IMPORTANT
The DTZ-8R-1 does not support wall plate mounting.

2. Plug the AC adapter (yellow tip) into the base unit, and route the cord 
through the molded channel on the back of the base unit.
3. Plug one end of the short telephone cord (locally supplied) into the LINE 
jack on the base unit.  If the NEC multiline (wired) phone is used, 
connect a line cord from the LINE OUT jack on the base unit to the 
multiline phone.
4. Place the base unit on the posts of the wall screws and push down until 
it is firmly seated.  
5. Plug the other end of the short telephone cord into the telephone wall 
jack.  
6. Plug the AC adapter into a standard 120 VAC wall outlet.
