OPERATING INSTRUCTIONS

To make a quick temperature measurement, squeeze the
measurement trigger on the front of the grip and hold it for at
least one second while pointing the laser at the target. Note that
the SCAN icon appears along with the measured temperature
while you are squeezing the trigger. When you release the trigger,
the SCAN icon disappears and is replaced by the HOLD icon for
no more than seven seconds. After seven seconds, the IRT657's
auto power off function kicks in and shuts off the thermometer to
prevent battery discharge.
The IRT657 will not make accurate measurements if there is glass
or plastic between the thermometer and the target.
To change the IRT657's default measurement unit from
degrees Celsius (°C) to degrees Fahrenheit (°F), press the °C/°F
button below the display at right to make the icon °F appear on
the right side of the display. To return to Celsius units, press the
°C/°F button again.
To turn off the backlight, press the button (callout G of
Fig. 1) below the display at left.
To turn off the laser pointer, press the button (callout F of
Fig. 1) below the center of the display.
