* To save power, the logger's LED flashing-cycle can be changed to 20s or 30s via the
supplied software.
** To save power, alarm LEDs for temperature and humidity can be disabled via the
supplied software.
*** When both temperature and relative humidity readings exceed alarm level
synchronously, LED status indication alternate every cycle. For example: If there is only
one alarm, the REC LED blinks for one cycle and alarm LED will blink for next cycle. If
there are two alarms, REC LED will not blink. First alarm will blink for first cycle and the
next alarm will blink for next cycle.
**** When the battery is low, all operations are disabled automatically.
