INSTALLATION (cont’d)
Internal Battery Activation and/or Replacement
A type CR2032 battery is installed in a compartment behind the
front panel of the homebase. If the unit is being used for the
first time, the battery must be activated. A plastic insulator pre-
vents contact with the battery terminals. The insulator must be
removed for the calendar/clock backup functions to operate. To
remove the insulator, simply pull out the plastic tab extending
from the right side of the unit below the marker pen.
To remove and replace the battery, proceed as follows:
1. Lay the homebase on a flat surface with the front panel facing up.
2. Grasp the center of the front panel at the top and bottom edge, and bow the panel out until it clears
the left side by the control buttons. Remove the panel to reveal the battery compartment cover.
3. With your thumb, press the cover in the direction indicated by the arrow until it disengages. Lift off
the cover.
4. Carefully remove the battery.
5. Insert the battery into the compartment, paying special attention to battery orientation (+ side
facing up).
6. Replace the battery compartment cover by first engaging the right-hand tabs in the slots; then
press down and slide the cover to the left to secure it into place.
7. Replace the front panel by engaging the right side under the protruding lip; then slightly bow the
panel out and slide the left side under the lip by the control buttons.
8. The battery backup feature should now be operational.
