The GREEN LED single-blinks every 5 seconds (STANDBY mode
is active and the logger is not recording).

the instrument will enter SLEEP mode and wait for either another
button press or the recording start time to arrive (if a recording is
scheduled). While in SLEEP mode, the LEDs will not blink.

normal STANDBY mode.
