• Set your thumb in the oval hollow on the back of
the unit, press down and slide the battery hatch
out as shown in fig. 11.
• Remove the battery hatch.
• Remove the old batteries and dispose of them
as required in the containers provided for this
purpose.
• Insert 4 new AAA - LR03 batteries, preferably
alkaline, carefully complying with the position
indicated in their housing.
• To close the hatch, slide it in the opposite direction from which it was opened.
• After changing the batteries, let the thermometer stabilize for 20 minutes before
taking a temperature reading, or run a manual quick calibration (MQCS, par. #8).
Remove the batteries if you do not expect to use the thermometer for a long
time.
CLEANING THE WAVEGUIDE: the thermometer waveguide (fig. 1) is very delicate.
Therefore, when the thermometer is not being used, we recommend that you always
keep the cap on. However, if you need to remove dust or dirt from the waveguide or
sensor at its base, use a cotton swab that has been slightly dampened with alcohol.
Remove all dirt and make certain that nothing accumulates at the bottom of the
waveguide where the sensor is located. Do not use any other objects or liquids as
the surface of the sensor could easily be scratched or damaged. Never let any excess
liquid penetrate into the waveguide and sensor.
CLEANING THE THERMOMETER BODY: use a soft cloth dampened with soap and
water and possibly re-wipe with a sodium hypochlorite disinfectant.
DO NOT USE the thermometer for at least 30 minutes after cleaning.
