12. Care And Cleaning
Use an alcohol swab or cotton tissue moistened with alcohol (70% Isopropyl)
to clean and disinfect the thermometer casing and the measuring probe.
Ensure that no liquid enters the interior of the thermometer. Never use abrasive
cleaning agents, thinners or benzene for cleaning and never immerse the
instrument in water or other cleaning liquids. Take care not to scratch the
surface of the probe lens and the display.
It is important to clean the thermometer before and after each use. A build up
of ear wax on the lens reduces the infrared picked up by the sensor, which can
result in lower temperatures. Ear wax is also acidic and can corrode the lens of
the thermometer if not cleaned regularly.
13. Battery Replacement
This thermometer is supplied with one lithium battery type, CR2032.
1. The battery needs replacing when only the icon is shown
on the display. (Figure 7)
2. Loosen the screw with a screwdriver, and lift the screw up
manually, then remove the battery cover by sliding in the
direction shown. Remove the battery and replace with a new
one.
Note: Battery cover should be installed correctly before use to avoid
potential risk of electric shock
