5. Nastavení
5.1 Instalace baterie
- Hlavní zobrazovací jednotka: Open the battery compartment cover on the back of the main unit. Insert 3 x AAA 1.5V alkaline batteries, ensuring correct polarity (+/-). Close the cover.
- Dálkové senzory: Open the battery compartment cover on the back of each remote sensor. Insert 2 x AAA 1.5V alkaline or lithium batteries, ensuring correct polarity (+/-). Close the cover.
Important Battery Notes:
- Nekombinujte staré a nové baterie.
- Do not mix battery types (e.g., alkaline and lithium).
- For environments with temperatures below -20°C (-4°F), use lithium batteries in the remote sensors for optimal performance.

5.2 Synchronizace senzorů
After installing batteries in both the main unit and the remote sensors, the main unit will automatically attempt to connect with the sensors. If a sensor's data is not displayed or communication is lost:
- If the transmitter has been replaced with a new battery, it is necessary to manually press and hold the CH button to receive the transmitter data again.
- Ensure remote sensors are within the transmission range (up to 100m/328ft in open areas).
- Allow up to one hour for the sensors to stabilize and display accurate readings due to signal filtering.
5.3 Možnosti umístění
Both the main display unit and the remote sensors offer flexible placement options:
- Stolní stojan: Use the retractable stand on the back of the units to place them on any flat surface.
- Montáž na stěnu: Utilize the integrated hanger hole on the back of the units to mount them on a wall. (Mounting hardware is not provided).
Úvahy o umístění senzoru:
- Place remote sensors in a sheltered area to prevent direct exposure to sunlight or heavy rain, even though they are IPX4 waterproof. Examples include under eaves or on a balcony.
- The wireless sensors have a range of 300 feet in open air and approximately 100 feet in most real-world installations (through walls, etc.).
