This predictive clinical digital electronic thermometer is for the intermittent
measurement and monitoring of human adult and pediatric body temperatures;
orally, and under the arm.
This thermometer can be used with or without
a tip cover. To use a cover, slide onto sensor
tip until fully engaged and peel off paper.
Covers are for single use, do not reuse. If
thermometer has been in a cold environment,
allow it to warm up to room temperature for
about 15 minutes before use. Avoid storing at
temperatures above 140
˚
(60
˚
C).
This thermometer IS intended to be used:
• For self-measurement/monitoring of human body temperature whereas the
person being measured may be the user/operator of the device.
• Orally, or Under the Arm (axillary).
• Adults
• Pediatric
This thermometer IS NOT intended for use with:
• Neonatal
General Warnings
• Contact your physician in case of prolonged fever as this requires medical
attention, especially for young children.
• Self-measuring means monitoring, not diagnosis or treatment. Under no
circumstances should you independently alter the dosages of any drugs
prescribed by your physician.
• Do not use this device if you think it is damaged or anything appears unusual
(e.g. sporadic operation, open packaging upon purchase).
• To avoid possible injury, do not run or walk while using this device.

• Do not dispose of the battery or device in fire; the battery may explode.
• Do not use a metal tool to replace the battery; doing so may short circuit the terminals.
• Do not attempt to recharge the battery as they are not rechargeable.
• Only open the thermometer battery cover to replace the battery.
• Do not open/modify this device; inaccuracy and/or harmful injury may result.
• Performance of this thermometer may be degraded if used outside of its specified
operation temperature and humidity rating, or if stored outside of its specified
storage temperature and humidity rating. Avoid dust or storage in direct sunlight.
• Performance of this thermometer may be degraded if the device is exposed to
mechanical shock.
• Performance of this thermometer may be degraded if the patient’s temperature is
lower than that of the ambient.
• Performance of this thermometer may be degraded if the tip is dirty or damaged;
ensure the tip is clean before using.
• Performance of this thermometer may be degraded if the probe cover is dirty or
a probe cover not intended for use with this device is used.
• Any probe covers that may be included in this device package are for single use only.
• This device contains sensitive electronics components. Avoid strong electrical or
electromagnetic fields in the direct vicinity of the device (e.g., mobile telephones,
microwave ovens). These can lead to temporary impairment of the measuring
accuracy. Move the device to another location if interference is determined.
Maintain a minimum distance of 3.3 m from such devices when using this unit.
• According to international standards, your device should be checked for
accuracy every 2 years.
How to Take a Temperature:
Press power button to turn unit on. Display should read “188.8” to confirm
normal function. An “Err” message indicates unit is not working properly. The
last recorded measurement will show for 2 seconds, followed by “- - -” and a
flashing “F” or “C”, indicating that thermometer is ready for use.
Oral Use:
• Do not drink hot or cold liquids or exercise before use.
• Place sensor tip under tongue as shown in Figure A.
• Accurate temperature reading will take approximately 30
seconds. An open mouth or improper placement could
make reading take longer.
Underarm Use:
• Wipe underarm with dry towel.
• Place sensor tip in armpit and lower arm against body as
shown in Figure B.
• Accurate temperature reading will take approximately 5
minutes with proper use.
Reading the Temperature:
For readings 99.5
˚
F (37.5
˚
C) and below, the thermometer
beeps 10 times to indicate temperature is within normal range.
For readings above 99.5
˚
F (37.5
˚
C), the thermometer emits a series of short,
rapid beats to indicate a possible high temperature.
Changing from °F to °C:
With the thermometer turned off, press and hold the power button for 5
seconds. An “°F” or “°C” will appear on the display, blinking. Press the
ON/OFF button to toggle to the opposite temperature setting. After 4 seconds
your thermometer will be ready for use.
How to Clean:
Clean thermometer after every use. There are 2 cleaning options below:
1. Alcohol:
Clean
sensor tip with 70% isopropyl alcohol. Wipe dry with
