8.4.4 Fahrenheit or Celsius Conversion
The TemporalScanner™ can be used in either °F or °C. To convert from one scale to the
other, the only tools necessary are a paper clip and the tip of a small screwdriver.
To convert to Fahrenheit or Celsius:
1. Bend one leg of a paper clip and insert it into the hole in the side of the plastic
housing.
2. Push to release the battery cover, and then remove the battery.
3. Slide the switch to left (Celsius) or right (Fahrenheit) with the tip of a screwdriver.
4. Replace battery and cover.
• After converting to Fahrenheit, the readings on TemporalScanner™ and the
monitor might be slightly different. The readings on TemporalScanner™
would be more accurate.
8.4.5 Replacing the Battery
To replace the battery, follow this procedure:
1. Bend one leg of a paper clip and insert it into the pinhole in the side of the plastic
housing.
2. Push to release the battery cover, and then remove the battery.
3. Replace the battery into the compartment.
4. Reinstall the battery cover.

■ Cleaning the case
Message/Issue Cause Solution
Abnormally low
Temperature
Dirty Lens Clean lens of scanner every two weeks.
Releasing the button
before finished measuring
Release the button after finished
measuring.
Measuring when an ice
pack or wet compress is on
the forehead
Remove ice pack or wet compress, wait
2 minutes, and re-take temperature.
Measuring a completely
diaphoretic patient
Complete diaphoresis includes
diaphoresis of area behind the ear and
suggests that the temperature is
rapidly dropping. Use an alternative
method of temperature measurement
in these cases until the patient is dry
and the temporal artery measurement
can be repeated.
Improperly scanning down
the side of the face
Scan straight across forehead. The
temporal artery is closest to skin in that
area.
Abnormally high
temperature
Anything covering the area
to be measured would
insulate and prevent heat
from dissipating, resulting
in false high readings.
Confirm measurement site has not
recently been in contact with heat
insulators such as hats, blankets, and
hair. Scan the area not covered or wait
about 30 seconds for the previously
covered area to equilibrate to the
environment.
