REIZEN Talking Digital Thermometer
Model # BT-A31
INSTRUCTIONS
Intended Use
Digital Thermometer, Model # BT-A31 is intended for monitoring human body temperature by physician or consumers in hospital or home.
Operation
- When the thermometer is ready to measure the temperature, you will hear audio announcement "Please measure".
- When the measurement is complete, you will hear the audio announcement for the measured result.
- Press blue audio button again, the latest temperature reading will be announced & displayed on the LCD screen.
Understanding Temperature Readings
What is a "Normal" temperature?
Although the generally accepted "normal" temperature reading is 37.0 °C/98.6°F, temperature readings can vary from 36.1°C/97.0°F to 37.2°C /99.0°F and still may be considered "normal". Variations in temperature can be attributed to activities such as exercise, smoking, eating and drinking. Your temperature is lower in the morning than in the afternoon. Other variations may be due to the location of the temperature reading. While the oral temperature follows the guidelines previously described, a rectal temperature is generally 0.5°C/1.0°F higher. Conversely, an axillary (under the arm) temperature will be 0.5°C/1.0°F lower.
How to switch voice processor announcement between English and Spanish
During POWER OFF mode, press POWER button for about 10 seconds until you see 01 displayed on LCD, then release the POWER button. Continually press POWER button to allow to switch the voice announcement between English and Spanish, 01 means English, 02 means Spanish.
How to switch Celsius and Fahrenheit degrees on display screen
During POWER OFF mode, press POWER button for about 15 seconds until "C" or "F" symbol blinks on LCD display, then release POWER button. Continually press POWER button to allow you to prompt to switch display to either Fahrenheit or Celsius.
Features of your digital thermometer
The thermometer features a distinct Probe Tip designed for temperature measurement. The front side displays a clear Display Window, while the back side houses the Power Button.

Taking a Temperature
Taking an Oral temperature
Place the probe tip under the tongue and keep it near to the heat pocket as close as possible.
Approximate measuring time: 8 seconds.
Suggestion: Close your mouth for at least 2 minutes before taking temperature.
Taking a Rectal temperature
Apply a water soluble lubricant to the probe cover. Gently insert the probe (MAXIMUM 1/2") into the rectum.
Approximate time for measurement: 10-30 seconds.
Note: Rectal temperatures are generally 0.5 C/1.0 °F higher than oral readings.
Replacing the Battery
The battery in your digital thermometer needs to be replaced when you see the [battery-low-icon] appear at the bottom of right corner.
Replace the batteries with 2 CR2025.
To replace the battery
- Remove the battery cover from the back of the thermometer.
- Remove the plastic security chip from battery compartment.
- Use a non-metal pointed tool to remove the battery.
- Place battery cover back after the 2 new CR2025 (2*3V) batteries have been replaced.
The battery compartment is located on the back of the thermometer and accommodates two CR2025 batteries.
Note: Please properly discard the batteries. KEEP away from small children and heat.

Recommended separation distances between portable and mobile RF communications equipment and the digital thermometer.
Digital thermometer is intended for use in an electromagnetic environment in which radiated RF disturbances are controlled. The customer or the user of the digital thermometer can help prevent electromagnetic interference by maintaining a minimum distance between portable and mobile RF communications equipment (transmitters) and the digital thermometer as recommended below, according to the maximum output power of the communications equipment.
| Rated maximum output power of transmitter(W) | Separation distance according to frequency of transmitter(m) | ||
|---|---|---|---|
| 150 KHz to 80 MHz | 80 MHz to 800 MHz | 800 MHz to 2.5 GHz | |
| 0.01 | d = 1,2√P 0.12 | d = 1,2√P 0.12 | d = 2,3√P 0.23 |
