Initial Diagnosis:

Test with Another Phone: Start by attempting a Bluetooth measurement using a different smartphone. This step helps identify if the issue is related to your phone's Bluetooth connectivity or the analyzer.

Forcing a Restart of the Analyzer:

Should the problem not be phone-related, a forced restart of the analyzer might be necessary. Follow these steps to refresh its power source and potentially resolve the issue:

1. Preparation:

Remove the Analyzer: Safely remove the analyzer from the water. Ensure you're in a dry, clean space before proceeding. Detach the rubber ring and usage cap to expose the probe.  

2. Cleaning the Device:

Dry Wipe: Use a clean, absorbent cloth to remove any moisture or debris, particularly focusing on the area around the probe.

3. Disassembly:

Access the Battery: Carefully remove any adhesive tape and unscrew the upper part of the analyzer using a clockwise motion, as it is a left-hand thread.

4. Battery Disconnection:

Unplug Connector: Locate and gently pull the white connector attached to the red and black cable to disconnect the battery. Wait for approximately 10 seconds before reconnecting.  

5. Reassembly:

Check the Seal: Ensure the seal is properly positioned before screwing the upper part back on, using a counter-clockwise motion for the left-hand thread.

Replace the Rubber Ring: Reattach the rubber ring, followed by the usage cap.

6. Final Steps:

Return to Water: Place the analyzer back into the water.

By systematically troubleshooting the connectivity issue, you can identify and possibly resolve the problem, ensuring your analyzer continues to perform optimally. Thank you for your cooperation and commitment to maintaining your device.
