How to Connect and Use the Probe with Display?
The probe is factory-calibrated and ready to use with batteries installed.
1, Replace the bottom cap of the probe. Open the battery cover, press the power button, and tighten the cover. Attach the floating ring and place the probe in water.
2, After powering on the display, press and hold the middle button for 3+ seconds until you hear a beep. The "!" icon disappears — connected.
3, Note: If not connected within 10 mins, restart the probe.
