paper clip, to press the Max /Min Button (Figure 12) on the gauge.
Press once to read the maximum, and once again to read the
minimum. Press the button a third time to return to the current
reading. The gauge shows MAX or MIN when either of these values
is displayed.

A slide switch on the side of the gauge (Figure 13) allows you to
select between °Centigrade and °Fahrenheit temperature readings.
Slide the switch UP to select °Centigrade; and DOWN to select
° Fahrenheit.
The gauge is powered by a 3.0 volt, lithium, Type CR2032 battery
which you can obtain locally.
The battery is contained in a built-in slide in the top of the gauge
(Figure 14). Just pull the battery slide up with your finger to open,
and remove the battery. When replacing the battery, notice that the
battery is marked with a “+” sign on one side, and the battery slide
is marked with two “+” signs (Figure 15). All “+” signs must be on
the same side and must face the front of the gauge. With the battery
in the slide, press the slide downward until it clicks into place.
