LED screen shows LO if temperature reading is below 89.6°F.
LED screen shows HI if temperature reading is above 109.2°F.
It shows ERR if the operation condition is beyond 60.8°F-104°F.
Solutions of LO or HI reading:
Make sure Earmo is operated under proper instruction.
The reading LOW might due to probe is not firmly inserted
into ear canal. Please insert firmly during the next
measurement.
The reading LOW might due to probe covered by filthy
objects. Please use alcohol pad to wipe it.
Solutions of HIGH reading:
Please use Earmo when the surrounding temperature is
between 59°F to 95°F.
