CAUTION

1. WHEN DEVICE IS IN USE, DO NOT LOOK DIRECTLY INTO THE LASER BEAM–PERMANENT EYE DAMAGE MAY RESULT.

2. USE EXTREME CAUTION WHEN OPERATING THE LASER.

3. NEVER POINT THE DEVICE TOWARDS ANYONE’S EYES.

4. KEEP OUT OF REACH OF ALL CHILDREN.
STORAGE & CLEANING The thermometer should be stored at room temperature between –20 to +65

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 us ing only a soft cloth or c otton s wab with water or m edical alcohol. A llowing the lens to f ully dry before us ing the thermometer. Do not
submerge any part of the thermometer.

BATTERIES

The thermometer incorporates visual low battery indication as follows:

‘Battery OK’: measurements

are 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.

Note: Under the electromagnetic field of 3V/m from 200 to 600 MHz, the maximum error is 10 oC (18 oF).

Caution: The measure range is for thermometer only. User should choose proper probe types for different kinds of application.

Please make sure the target to be measured will not exceed the temperature range of the probe to avoid permanent
damage of the thermocouple probe.

Caution: To avoid electric shock and thermometer damage, do not measure live circuit where voltage exceeding 24V AC RMS or

60V DC with the thermocouple probe.

EMC/RFI: Readings may be affected if the unit is operated within radio frequency electromagnetic field strength of approximately 3 volts per

meter, but the performance of the instrument will not be permanently affected.
