SETUP INSTRUCTIONS
ACTIVATE THE UNIT
To begin, remove the plastic film protecting the
display. Holding the unit in your hand with the back
facing you, open the battery compartment by
pushing its cover down (in the direction of the
arrow on it) and away from the unit. Remove the
external sensor cable from the large well of the
compartment so it hangs loosely below the unit,
but do not remove the twist tie keeping the cable
in a bundle.
Note from Fig. 3 that an “AAA” battery (callout 11)
is already installed in the battery compartment.
To extend the battery’s life and to protect the unit
from possible battery leakage during storage, the
unit ships with a plastic tab (callout 12) between
the battery’s anode and the metal plate it connects

Figure 2 shows the back of the unit with the
battery compartment closed. Note:
• The °F/°C switch (callout 5) at the top of the
case.
• The two hanger holes (callouts 6 and 7) at the
top corners of the case. Use these to wall-mount
the unit.
• The rectangular recess (callout 8) near the
bottom of the case. Use this recess to raise the
unit’s kickstand for mounting on a horizontal
surface.
