*1 All of these operations, except "Power off" and "Charging", require the power to be on (for example, the battery
replacement LED does not flash when the power is off)
*2 If "Battery replacement warning" and "Excessive input" occur at the same time, the battery replacement warning
takes priority.
*3 During charging, the power LED is lit in a color other than red.
*4 Recording in logger mode is possible with all LEDs lit.
*5 Recording and time correction are complete, and the recorded data is ready to be collected by the main unit.
*6 Once GPS sync is complete, the LED will remain lit even if GPS is lost.
*7 When “logger mode” is set, “sensor connection status and adjustment” is replaced by “logger mode recording
status”.
Lit: Not recording Unlit: Recording in progress or complete
When an external sensor is connected, logging is performed using the external sensor, but the connection status
is not displayed on the LEDs.
