The sensor lens is the most delicate part of the TN4 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 TN4. Do not submerge any part of the TN4. The TN4
should be stored at room temperature between –20 to +65 oC.
LCD ERROR MESSAGES
The TN4 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.
For all other error messages it is necessary to reset the TN4. To reset the TN4,
turn the instrument off, remove the battery and wait for a minimum of one
minute, reinsert the battery and turn on. If the error message remains please
contact the Service Department for further assistance.
BATTERIES
The TN4 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 instrumentoff before replacing the battery otherwise the TN4 may
malfunction.
Dispose of used battery promptly and keep away from children.
