PRU+ Basics
Turning the PRU+ on
To begin the installation process, the PRU+ must be turned on. To turn the PRU+ on, simply connect
the AC adapter to the back of the PRU+ (See Figure 1 below ) and plug the adapter into a standard wall
outlet.
Note: Do not connect the telephone line.
The PRU+ will immediately activate, sounding one
or more beeps, and is ready for the next step in
the installation process.

Turning the PRU+ off
Removing/disconnecting AC power will not turn the PRU+ off. Removal of AC power will cause the
PRU+ to function using its internal battery. The PRU+ will continue to operate until the internal battery
is exhausted, or the PRU+ is turned off by using the LOCK.
To turn the PRU+ off, the use of the LOCK is required. Simply press the PRU+ button on the LOCK,
while holding the LOCK within three feet of the PRU+. The front panel display (see
Figure 2 below) will display two choices: "A=Turn PRU+ Off" and "B=Function Mode". Press the "A"
button (see Figure 2 : Front Panel Display) on the PRU+ front panel. When the "Remove AC power
now..." message is displayed, unplug the AC adapter. The PRU+ will then shut off. If AC power has
already been disconnected, the PRU+ will shut off as soon as the "A" button is pressed. While the
PRU+ is off, either because it was deliberately turned off or has turned off due to an AC power loss long
enough to exhaust the internal battery, all stored information is maintained using a separate back-up
battery.
