Installing the Operational Battery Pack

First unplug the clock. The door to the battery pack compartment is located on the

bottom edge of the back of the clock. Remove the screw that secures the door.

The door may be tightly fitted. Insert a thin knife blade under the bottom of the door

at the screw end and rotate the blade to open the door.

Connect the battery cable to the connector on the left side of the compartment. Note

that the two ridges on the side of the battery connector should be facing down to line

up with the slots in the clock’s power connector. Turn the battery so that the cable

connection is on the bottom. Insert the battery pack into the clock with the wires

inserted into the opening in the side of the compartment. This is important since the

battery door can’t be attached if the battery is sitting on top of the wires. You may

need to use something like a pencil or ruler to push the wires into the opening.

Attach the door by inserting the door tabs into the left side of the compartment and

firmly rotating the door into place. If the door won’t close check to make sure the

wires aren’t under the battery. Plug in the power supply once the battery door is

secure. The ATR240 should be plugged in for 12 hours to fully charge the battery

pack.

Cleaning the ATR240

Do not use cleaning products that contain alcohol or other strong chemicals as they

could discolor or crack the terminal housing. Use a soft damp cloth to remove dirt.

Wipe dry.
