ACU Basics

Turning the ACU on

To begin the installation process, the ACU must be turned on. To turn the ACU on, simply connect the

AC adapter to the back of the ACU (See Figure 1 below) and plug the adapter into a standard wall

outlet. Note: Do not connect the telephone line. The ACU will immediately activate, sounding one

or more beeps, and is ready for the next step in the installation process.

Turning the ACU off

To turn the ACU off, the use of the LOCK is required.

Removing/disconnecting AC power will not

turn the ACU off. Removal of AC power will cause the ACU

to function using its internal battery. The ACU will continue to operate until the internal battery is

exhausted, or the ACU is turned off by using the LOCK.

Using the LOCK, press the iRX button on the LOCK, while holding the LOCK within three feet of

the ACU. The front panel (see Figure 2 below) will display two choices: "A=Function Mode” and

"B=Turn ACU Off". Press the "B" button on the ACU front panel. When the "Remove AC power now..."

message is displayed, unplug the AC adapter. The ACU will then shut off.

While the ACU 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.
