STORAGE & CLEANING
OS418L should be stored at room temperature. The sensor lens is the most delicate part of the thermometer. The lens
should be kept clean at all times, care should be taken when cleaning the lens using only a soft cloth or cotton swab
with water or medical alcohol, allowing the lens to fully dry before using the thermometer. Do not submerge any part of
the thermometer.
LCD ERROR MESSAGES
The thermometer incorporates visual diagnostic messages as follows:
‘Hi’ or ’Lo’ is displayed when the temperature being measured is outside of the settings of
HAL and LAL.
_
_ _
_
‘Er2’ is displayed when the thermometer is exposed to rapid changes in the ambient
temperature. ‘Er3’ is displayed when the ambient temperature exceeds 0
o
C (32°F) or +50
o
C
(122°F). The thermometer should be allowed plenty of time (minimum 30 minutes) to
stabilize to the working/room temperature.

Error 5~9
, for all other error messages it is necessary to reset the thermometer. To reset it,
turn the instrument off, remove the battery and wait for a minimum of one minute, reinsert
the battery and turn
_

‘Hi’ or ’Lo’ is displayed when the temperature being measured is outside of the
measurement range.
BATTERIES
The thermometer incorporates visual low battery indication as follows:
‘Battery OK’: measurements
are possible
‘Battery Low’: battery needs to be
replaced, measurements are still possible
‘Battery Exhausted’: measurements are
not possible
When the ‘Low Battery’ icon indicates the battery is low, the battery should be replaced immediately with AAA, 1.5V batteries.
Please note: It is important to turn the instrument off before replacing the battery otherwise the thermometer may malfunction.
Dispose of used battery promptly and keep away from children.
