steady green and does not turn normal blue until the initialization is completed. Note: If
the steady green persists for an hour, the device initialization fails and the device is
faulty.

LED Keeps Blinking Blue at an Interval of 0.2s (in Fit Mode)

Sometimes the AP performs software upgrade after power-on. During this period, the
LED keeps blinking blue at an interval of 0.2s and does not turn steady blue until the
upgrade is completed. Note: Do not plug or unplug the power cord when the LED is
blinking as software upgrade takes time. If the blinking persists for 10 minutes, the
device fails to complete software upgrade and is faulty.
