Replacing the batteries
The thermometer is supplied with two 1.5 V batteries type AA (LR 6). For best performance, we recommend Duracell® alkaline batteries. Insert new batteries when the battery symbol appears on the display.
Open the battery compartment. Remove the batteries and replace with new batteries, making sure the poles are in the right direction.
Slide battery door back until it snaps in place.
To protect the environment, dispose of empty batteries according to national or local regulations.
Calibration
The thermometer is initially calibrated at the time of manufacture.
If this thermometer is used according to the use instructions, periodic readjustment is not required. If at any time you question the accuracy of temperature measurements, please contact Welch Allyn (see page 14).
Manufacturing date is given by the LOT number located in the battery compartment. The first number after LOT represents the last digit of the year of manufacture.
The next three digits give the day of the year of manufacture.
An example: LOT 0116 xx xx – this product has been manufactured on the 116th day of the year 2000.
