4. Opsette
4.1 De haadienheid oandriuwe
The main unit can be powered in two ways:
- Batterij Power: Insert 3 AA batteries (not included) into the battery compartment on the back of the main unit.
- Cable Power: Plug the included Apple data cable into the main unit's charging port and connect it to a USB power source.

Figure 1: Main unit power supply options (battery and cable).
4.2 Setting Up Wireless Sensors
The three wireless transmitters are identical. To differentiate them and ensure proper connection:
- On the back cover of each transmitter, locate the channel dial and set it to 1, 2, or 3 for each respective sensor.
- Insert 2 AAA batteries (not included) into each transmitter. The indicator light on the transmitter will flash red, signaling it is attempting to connect.
- The main unit will automatically connect to the transmitters. If a sensor does not connect immediately, it will attempt to reconnect in approximately 60-second cycles. To expedite the connection, remove and reinsert the batteries in the transmitter and wait for the red light to flash.

5.2 Seleksje fan temperatuerienheid (°C/°F)
To switch between Celsius (°C) and Fahrenheit (°F), press the '°C/°F' button located on the right side of the main unit.
5.3 MAX/MIN-rekord
The thermo-hygrometer records the maximum and minimum temperature and humidity values over the past 24 hours. Press the 'MIN/MAX' button on the left side of the unit to cycle through current, maximum, and minimum readings.
5.4 Air Comfort Indicator
The display includes an air comfort indicator to quickly assess indoor conditions:
- DROECH: Feuchte < 40%
- KOM (Komfort): 40% < Feuchte < 70%
- WIET: Feuchte > 70%

6. Mounting opsjes
Both the main unit and the wireless transmitters offer flexible mounting options:
6.1 Main Unit Mounting
- Oprjocht: Use the integrated stand to place the unit on a tabletop or desk.
- Wall Mount: Brûk it ophanggat oan 'e efterkant om it oan in muorre te montearjen.
- Magnetyske efterkant: The unit has a magnetic back for attachment to metallic surfaces like refrigerators.
6.2 Transmitter Mounting
- Oprjocht: Place the transmitter on a flat surface.
- Wall Mount: Use the hanging hole for wall mounting.
- Lanyard/Suction Cup: The transmitter comes with a lanyard and suction cup for versatile placement, such as hanging or attaching to glass.

7. Underhâld
7.1 Batterijferfanging
Replace batteries in the main unit (3 AA) and transmitters (2 AAA each) when the low battery indicator appears on the display. Always use new batteries and ensure correct polarity.
7.2 Cleaning
Wipe the device with a soft, dry cloth. Do not use abrasive cleaners or immerse the unit in water.
7.3 Miljeu ôfwagings
To prolong the life and accuracy of your device, avoid exposing it to:
- Direct sunlight or extreme heat sources.
- High humidity or direct water exposure.
- Excessive dust or corrosive gases.
8. Probleemoplossing
8.1 Sensor Not Connecting
- Ensure batteries are correctly inserted and have sufficient charge in both the main unit and the sensor.
- Verify that the sensor's channel dial is set to a unique number (1, 2, or 3).
- Move the sensor closer to the main unit to check if it's a range issue. The maximum range is 100m/328ft in open air, but obstacles like walls can reduce this.
- Remove and reinsert the batteries in the problematic sensor to force a reconnection attempt.
8.2 Blurring Display
A blurring display typically indicates low battery power. Replace the batteries in the main unit.
8.3 Unkrekte mjittingen
- Ensure sensors are not placed in direct sunlight or near heat/cold sources, which can skew readings.
- Allow the main unit and sensors to stabilize in their respective environments for at least 30 minutes after setup for accurate readings.
- Compare readings with another known accurate thermometer/hygrometer if possible.
