Why does the battery LED blink periodically?

Why does the battery LED blink periodically?

• A. To indicate a fault condition in the sensor
• B. To show that the system is periodically checking the battery BT1
• C. To indicate the AIP is in standby
• D. To show that the battery is charging

Answer: (B)

That periodic blink is a small heartbeat indicating the system is periodically checking the BT1 battery. It’s a low-power way for the device to verify that the battery is present and within acceptable voltage at set intervals, helping ensure readiness without keeping a constant check running. If the battery needed attention—low voltage, a loose connection, or a fault—the indicator would typically change to a different pattern or color rather than continuing to blink at a regular interval. So the blinking signal is best understood as the system routinely verifying the battery BT1.
