Instructions for use of the TempScan GT-302A Thermometer

(Unofficial instructions, use at your own risk)

I just figured out how to use mine again, lost the instructions a decade ago or so. Here goes:

Switching it on
Switch it on by pressing the on/MEM button. This will set the device in memory recall mode, indicated by the “M” symbol to the left in the display. The SCAN button will cycle between the 10 most recent temperature takings, taking #1 being the most recent.

Go to temperature taking mode
Press the on button again to put the device in stand-by mode for temperature monitoring. Over a bit less than 10 seconds, a progress report will appear near the top of the display showing 3 progressively thicker bars and finally a pictogram of an ear, accompanied by a beep.

Take the temperature
When the ear pictogram has appeared, the device is ready for temperature monitoring. Position the tip of the device in ear (with appropriate protection) and depress the SCAN button. Release the SCAN button when the device has beeped. The temperature may now be read from the display and will be stored in memory as reading #1.

Switching off the device
Depress the on/MEM button and wait for the device to switch off the display. Release button.

Shorter version:

Switch it on by pressing the on/MEM button. Press “on” again & wait 10 secs for small ear to appear in display. Take the temp by pressing SCAN until beep.
