To activate the nit:
1. Open the battery compartment (marked OPEN) on the
right side of the back of the unit by sliding its cover
down, in the direction of the arrow stenciled on it.
2. Remove the black activation tab under the R44
button battery. Discard the tab.
3. Install the battery in the well so its rounded side faces
down and its flat side (marked “ R44”) faces up. The
battery does not snap into place, so do not apply
downward pressure.
4. Replace the battery compartment cover by sliding it
up, in the direction opposite the arrow on it. The
pressure of the cover is what holds the battery in
place.

MOUNT THE UNIT
To leave the nit free to move on a horizontal
s rface, lift the foldaway stand on the back of the unit
by placing your fingertip in the recess on the bottom
edge of the unit.
To attach the nit to a wall or vertical s rface, obtain
a pair of Velcro strips and—without separating them—
trim them to a size of 1-3/4 in. by 3/8 in., or slightly
smaller than the recessed rectangular mounting area on
the top rear of the unit. Remove the paper backing from
one strip and press its exposed sticky side into the
recess. Remove the paper backing from the other strip
and press the unit against the wall or surface at the
desired position.
To detach the nit in order to change the battery, grab
it and pull until the two Velcro strips separate.
