When the main unit is left without any button operation or without receiving any signal of heart rate or wheel signal for about 15 minutes continuously, the power supply is shut down and the unit will go into the Sleep State, displaying only the clock (as in the left figure).
However, even in the Sleep State, the unit continues to count Elapsed Time TM.
When any button other than LT button is pressed, or the current signal is received, the screen wakes up and returns to normal display.
NOTE !: If the unit is left with the readout screen or the setup screen of target heart rate zone/Lap/Memory Record, the power saving feature might not work. Always leave your MSC in a main function for long records of time.
