Functional mode: each functional mode has 3 modes (not circulating, 2-99 cycles, forever circulating)
Size: as the picture
Short press: press key time is less than 2 seconds;
Long press: press key time more than 2 seconds;
Status: working status , set status, power-saving status.
Working status: start work after powering . Displays the remaining time of 1 channel, the parameters can be displayed the “channel select” to set ;
Set status: short press the “SET” key to enter “channel select” Status. Short press “OK” button to exit the setting;
Power-saving status:in this Status , digital tubes don’t display, and other features work correctly. Long press “OK” button after 5 seconds to enter power-saving status, press again “OK” button for 5 seconds or re-power to exit power-saving status.
Factory settings: press and hold “++” and “–” two button for 3 seconds, to restore factory settings, and the digital tube will turn open . After re-power , will run default parameters .
