Preparing for Installation

WARNING:

If there is not sufficient room on the existing wood mounting surface, either secure a new surface (a piece of plywood) or use wall studs to install the system unit. This ensures permanent mounting and will prevent wall damage.

The system unit should be connected to the same electrical branch circuit as the communications system control unit. If the communications system’s control unit is connected to an uninterruptible power supply (UPS) or surge protector, it is recommended that the mail system unit be connected to the same UPS or surge protector.
