Site Survey
Before installing this system, you need to be sure that the range of the system will be sufficient.
The transmitter and speech unit can be powered up, call button pressed, and then check that the
handset will ring from all areas in which it will be used.
.
Tip:
For longer range installations, locate the handset close to the front of the property, near a
window if possible. Concrete walls can reduce the open-air range of 400 metres/yards by 30-50%
per wall.
