Ble Transceiver; Clock - Stanley Healthcare WanderGuard BLUE User Manual

BLE Transceiver

Sends BLE message every 3 seconds
Used as a test mechanism for the BLE receiver:
If the BLE receiver does not receive the message, it means that the
Receiver is not operating properly.
This feature enables the Controller to monitor the Receiver that
communicates with the Tag. This test functionality prevents a situation
in which a resident could be without Tag protection due to a technical
problem without the staff knowing.

Clock

Maximum drift of 400 msec a day
Maximum drift of 1 minute in ~5 months period
The clock has a battery that is used only when the Controller is not powered
up.
Best Practice: It is recommended to synchronize the Clock using the
WanderGuard BLUE Manager once every 6 months because of the Clock
drift.
