4. Installation of the ZT (Zone Transceiver)
Explained below is how to install the ZT and precautions to be made when mounting it.
a. The ZT is a communication device that sends a weak signal as radio waves, it should not be installed
near and around equipment or an environment listed below to ensure the speech quality and various
kinds of control operations – care must be taken.
[Indoor Installation]
Do not install around equipment...

2. INSTALLATION PROCEDURE OF ZONE TRANSCEIVER (ZT)
STEP 1: When mounting a ZT on a wall/ceiling, observe the following instructions.
i Do not mount a ZT on a wall/ceiling which cannot sustain the weight of ZT (e.g. a plaster wall,
plywood wall).
ii Make a sufficient space so that the antenna can be placed at any angle.
iii When mounting a ZT on a wall which contains a reinforcing bar near the mounting location, place
the antenna at an angle...

STEP 2: Post the attached dimension drawing on the mounting location so as to mark the locations of screw 
holes. As shown Figure 2-7, two screw holes are provided as the lower mounting position. Depending 
on the mounting location, select either of the two mounting position.

STEP 5: If power feeding from the PCS is impossible, use the “AC adapter” for local power feeding. The “AC 
adapter” is connected to the ZT as shown below.

STEP 7: The angle of the antenna is variable between 0º and 180º as shown below. In a wall-mount installation, 
normally the antenna is set at an angle of 0º so that the antenna may be vertical with the radio zone.
Note:Since the antenna is easily broken, handle it with care.
