User should take M1 RF card to certain management system handle recharge first, and then put the M1 RF card to the clock in area, the LCD screen would display prompt message ‘6uoo--’, rest amount and etc one by one, at the same time, the valve would ON and gas meter enter into sleep mode. The rest amount would decrease progressively while using.

3. Check
