How do I check the Tag battery using the Detector, and what do the LED indicators mean?

Turn on the Detector, then place the Tag within 0.5 meters of the Detector; it constantly sends LF messages and will flash the Tag Battery LED for one second after receiving a BLE message from the Tag. A green flash indicates a good battery, a red flash indicates a low battery, and an ivory color means multiple Tags are sending BLE messages simultaneously. It is recommended to check Tag battery at least once a week.
