If the LCD screen of your RKI Gas Detectors is blank, first, ensure the unit is powered on by pressing and briefly holding the POWER/ENTER button. If it still doesn't turn on, the alkaline batteries may need replacement, or the Li-ion battery pack may need recharging. Replace the alkaline batteries or recharge the Li-ion battery pack.
