The longest period is 10 hours. The timing interval can be 10 minutes (within 1-hour timing) or 30 minutes (more than 1-hour timing). When the shut hours are set, the system comes into count down time and the oxygen concentrator LCD will shows the remaining time. When Remaining time becomes 0, the oxygen concentrator will shut automatically and will go to sleeping status. ♦ When the oxygen concentrator is in the dormant state, it can be restarted by use of wireless remote-control launcher. When it’s in the working state, the remote control can operate such activities as timing and shutdown. The Max. remote control distance is 50m.
