Troubleshooting

The phone does not detect the tag

• Confirm that NFC is enabled.
• Hold the tag against the back of the phone.
• Move the tag across the phone because NFC transmitter locations vary by model.
• On Android, confirm that NFC Tools is open.

Activation does not complete

• Enter exactly start in lowercase.
• Remove any trailing spaces from the text record.
• Select Write after creating the record.
• Read the tag again and check whether the status is On.
• Repeat the read/write operation if necessary.

The LED does not flash

Repeat the NFC write operation and hold the tag directly against the phone when the app displays Approach NFC Tag.

Positioning or signal quality is poor

• Confirm that the gateway and EH Locators are installed and started.
• Keep the tag within the recommended distance of the nearest installed tag.
• Move the tag away from deep metal structures.
• Avoid strong RF sources, including nearby Wi-Fi routers.

The installation environment is unsuitable

Keep the operating temperature below +60 °C. The IP64 rating protects against dust and splashing water, but it does not indicate protection against immersion or high-pressure water.
