Important Safety Information • If there is any temperature difference between the places where the unit is stored and where you are going to measure, leave the unit in the room where you are going to use it for more than 30 minutes to allow it to reach room temperature first, then measure.
Page 6
Important Safety Information • The “Repeatability” is 0.36 °F (0.20 °C). • The probe lens is the most delicate part of the thermometer. Use with care when cleaning the probe lens to avoid damage. a. When the probe lens becomes dirty, wipe it lightly with a soft dry cloth or a cotton swab. DO NOT wipe the probe lens with tissue paper or a paper towel.
2. Preparation Removing the Insulating Tape When using the thermometer for the first time, pull the insulating tape out of the battery compartment. Back of the unit The unit will turn on and after 1 minute the room temperature appears on the display. Note: •...
2. Preparation Switching between “°F” and “°C” This unit is set to “°F” as default. While the room temperature is displayed, press and hold the [START] button. While holding it down, press and hold the [ON/MEM] button until “°C” appears on the display with two beeps.
2. Preparation Setting the Buzzer The buzzer is activated by default, but can be deactivated. Note: The buzzer is only available in forehead measurement mode. Press the [ON/MEM] button. Press and hold the [ON/MEM] button for 3 seconds. The “ ”...
3. Using the Unit Taking a Reading Forehead Measurement Mode This mode displays the oral-equivalent value of the measured forehead temperature. Always make sure the probe lens is clean and undamaged, and the forehead is clean with no sweat, cosmetics, scars, etc.

3. Using the Unit Hold the probe lens 0.4 to 1.2 inches (1 to 3 cm) away from the center of the forehead. Note: • Holding the unit too long in the hand may cause a higher ambient temperature reading of the probe.
Page 13
3. Using the Unit Move the unit away from the forehead and check the measurement result. The display lights up for 5 seconds. Note: • If the result is higher than 108.0 °F (42.2 °C), “Hi” appears on the display. If the result is lower than 93.2 °F (34.0 °C), “Lo”...

3. Using the Unit Surface Measurement Mode Surface measurement mode shows the actual and unadjusted surface temperature of an object, which is different from the body temperature. This mode can help you determine if the object temperature is suitable for a patient or baby (such as baby milk).
Page 16
3. Using the Unit Note: • Move the probe lens as close to the object as possible when using in surface measurement mode (0.4 inches (1 cm) apart is recommended). Do not touch the probe lens to the object directly. •...
3. Using the Unit Using the Memory Function This unit automatically stores the last 25 measurement results (excluding Hi/Lo results). Note: • If the memory is full, the unit will delete the oldest reading. • When the unit is switched between “°F” and “°C”, all the readings stored in the memory are deleted. Press the [ON/MEM] button.
4. Troubleshooting and Maintenance The Icons and Error Messages In case of any of the below problems occur during measurement, check that no other electrical device is within 12 inches (30 cm) of the device. If the problem persists, please refer to the table below. Error Display Possible Cause Solution...

4. Troubleshooting and Maintenance Error Display Possible Cause Solution Change to a new battery. The battery is depleted. (Refer to sub-section 4.4) Remains on the display.
4. Troubleshooting and Maintenance Questions and Answers 1. The temperature indicated is rather high. • The unit has been stored in a cold room. When the unit has been stored in a cold room, the measured temperature may be rather high if you measure the temperature shortly after bringing the unit to a room that is at normal temperature.
Maintenance • Check the unit can be operated properly if it is dropped. If unsure, please contact OMRON customer service to have the unit checked. • When the probe lens becomes dirty, wipe it lightly with a soft dry cloth or a cotton swab.
