Battery Installation
Low battery warning:
When the battery power becomes low, the low battery symbol “ ”
will appear on the display. The thermometer can still be used during
this time, but the batteries should be replaced as soon as possible. If the
batteries run out completely, “Lo” will be displayed along with the
low battery symbol “ ”. In this case, the batteries will need to be
replaced before using the thermometer again.
CAUTION:
Risk of explosion if battery is replaced by an incorrect type. Dispose of
used batteries according to the instructions.
Replacing the Battery:
1. Gently slide the battery cover back.
2. Carefully remove the old batteries and properly discard.
3. Insert new batteries (Two 1.5V alkaline AAA(LR03) Size) according to
the proper polarity.
4. Slide the battery cover back on.
NOTE: Battery-operated
1. Please properly dispose of the batteries away from small children
and heat.
2. It is recommended to remove the batteries if the unit will not be

3. Batteries must be disposed of in accordance with local
environmental and institutional policies.
4. Dispose of used batteries in accordance with the applicable legal
regulations. Never dispose of batteries in the normal household
waste.

Tips for Measuring Human Temperature
Bear in mind that the thermometer needs to have been in the room in
which the measurement is taken for at least 30 minutes before use.
NOTE:
•Attempting to take temperature readings from sites on the body
other than the forehead may produce inaccurate results.
•The patient should remain still while the reading is being taken.
•Readings taken while asleep should not be compared directly to
readings taken while awake, as body temperature while asleep is
typically lower.
•Do not take body temperature readings within 30 minutes of being
outdoors, exercising or bathing.
