Setup
1. Charging the Main Display Unit
- Locate the USB charge port on the display unit.
- Connect the provided USB cable to the unit and to a compatible USB power source (e.g., computer, USB wall adapter - not included).
- The unit uses a 3.7V rechargeable lithium battery. Allow sufficient time for a full charge before first use.
2. Installing Wireless Sensor Battery
The wireless sensor requires one replaceable CR2032 battery. Open the battery compartment on the wireless sensor and insert the CR2032 battery, ensuring correct polarity. Securely close the compartment to maintain waterproofing.
3. Connecting the Wired Transducer
- Uncoil the cable transducer.
- Open the rubber cover on the cable transducer charge port on the main display unit.
- Carefully insert the cable transducer connector into the port, ensuring a firm connection.
