2. Setup

2.1. Battery Installation

The CEM DT-8806H thermometer requires batteries for operation. A battery is included with the product.

1. Locate the battery compartment cover on the handle of the thermometer.
2. Slide or open the cover according to the indicator.
3. Insert the batteries, ensuring correct polarity (+ and -) as indicated inside the compartment.
4. Close the battery compartment cover securely.

Note: Always use the specified battery type and dispose of old batteries responsibly.

2.2. Initial Power-On

After installing the batteries, the thermometer is ready for use.

1. Press the measurement trigger button to power on the device.
2. The LCD display will illuminate and show the last measurement or enter standby mode.

3. Operating Instructions

The DT-8806H offers two primary measurement modes: Body mode and Surface mode.

3.1. Switching Measurement Modes

To switch between Body and Surface measurement modes, locate the mode switch on the side of the thermometer.

• Slide the switch to the "Body" position for human body temperature measurements.
• Slide the switch to the "Surface" position for measuring the temperature of objects, liquids, or ambient air.

3.2. Measuring Body Temperature (Body Mode)

1. Ensure the thermometer is in "Body" mode.
2. Point the thermometer at the center of the forehead, maintaining a distance of 5-15 cm (2-6 inches).
3. Press the measurement trigger button.
4. The temperature reading will be displayed on the LCD screen within 0.5 seconds.
5. The thermometer will automatically store the reading in its memory.

Important: For consistent readings, ensure the measurement distance is maintained. If a person has just entered from outdoors, wait approximately 10 minutes for their body temperature to stabilize before measuring.

3.3. Measuring Object/Surface Temperature (Surface Mode)

1. Ensure the thermometer is in "Surface" mode.
2. Point the thermometer at the object or surface you wish to measure.
3. Press the measurement trigger button.
4. The temperature reading will be displayed on the LCD screen.

This mode is suitable for measuring temperatures of milk, bath water, room air, food, and other non-living objects.

3.4. Memory Function

The thermometer automatically stores the last 32 temperature measurements. To recall past readings, refer to the device's specific button functions (usually a "MEM" or "LOG" button, though not explicitly detailed in input, common for such devices).

4. Maintenance

4.1. Cleaning the Thermometer

To ensure accurate readings and hygienic use, regularly clean your thermometer.

• Wipe the thermometer body with a soft, damp cloth.
• For the sensor lens, use a cotton swab lightly moistened with alcohol. Clean gently to avoid scratching.
• Do not immerse the thermometer in water or any other liquid.
• Do not use abrasive cleaners or solvents.

4.2. Storage

Store the thermometer in a cool, dry place, away from direct sunlight, extreme temperatures, and humidity. Keep it out of reach of children.

5. Troubleshooting

This section addresses common issues you might encounter with your CEM DT-8806H thermometer.

5.1. Inconsistent Measurements

Problem: Measurements are always different when taken in quick succession.

Possible Causes & Solutions:

• Natural Skin Temperature Changes: Human skin temperature can fluctuate.
• Measurement Distance Variation: Ensure a consistent distance of 5-15 cm from the forehead.
• Air Temperature Changes: Significant changes in ambient air temperature can affect readings.
• Environmental Acclimatization: If a person has just come indoors from a different temperature environment, wait approximately 10 minutes for their body temperature to stabilize before measuring.
• Alternative Measurement Sites: For comparison or if forehead readings are consistently problematic, try measuring behind the ear, in the mouth, or under the armpit with a standard clinical thermometer (if applicable for comparison, though this is a non-contact device).

5.2. Incorrect Temperature Readings (e.g., always 95°F / 35°C)

Problem: The thermometer consistently displays an incorrect or fixed temperature, such as 95°F (35°C).

Possible Cause & Solution:

• Incorrect Measurement Mode: Ensure the thermometer is set to the correct mode for your intended measurement.
  • For human body temperature, the mode switch must be set to "Body".
  • For object or liquid temperatures (e.g., milk, bath water), the mode switch must be set to "Surface".
