5. Setup

5.1 Battery Installation

1. Locate the battery compartment cover on the back of the device.
2. Remove the cover by sliding or gently prying it open.
3. Insert one CR2 Lithium battery, ensuring the correct polarity (+/-) as indicated inside the compartment.
4. Replace the battery compartment cover securely.
5. The device display should activate, showing current temperature and humidity readings.

5.2 Initial Placement

For accurate readings, place the thermometer/hygrometer in a location free from direct sunlight, drafts, or heat sources. The device can be placed on a flat surface or mounted on a wall using the integrated mounting hole on the back.

• Wall Mounting: Use a small screw (not included) suitable for your wall type. Hang the device securely.
• Tabletop Placement: Ensure the device is stable on a flat, level surface.

6. Operating Instructions

6.1 Display Overview

The large digital display shows two main values:

• Upper Display: Current temperature in degrees Celsius (°C).
• Lower Display: Current relative humidity in percentage (% RH).
• Comfort Level Indicator: A small icon (e.g., a smiley face) indicates the current indoor climate comfort level based on temperature and humidity.

6.2 Max/Min Function

The device records the maximum and minimum temperature and humidity values measured since the last reset. To access these values:

1. Press the MAX/MIN button (if present, typically on the back or side). The display will show the maximum recorded temperature and humidity.
2. Press the MAX/MIN button again to view the minimum recorded temperature and humidity.
3. Press the MAX/MIN button a third time to return to current readings.

To reset the MAX/MIN values, press and hold the MAX/MIN button for a few seconds while viewing the MAX or MIN values. The memory will clear, and new maximum and minimum values will begin recording from that point.

6.3 Comfort Level Indicator

The comfort level indicator provides a quick visual reference for indoor climate conditions:

• Happy Face: Indicates optimal comfort (e.g., 20-25°C and 40-70% RH).
• Neutral Face: Indicates acceptable but not optimal conditions.
• Sad Face: Indicates uncomfortable conditions (e.g., too dry, too humid, too hot, or too cold).

Note: Specific ranges for comfort levels may vary slightly by model. Refer to the device's display for the exact icon representation.
