What to do if the LCD is blank on my RKI Instruments Monitor?
- BBruce SaundersAug 5, 2025
If the LCD screen is blank on your RKI Instruments Monitor, there are a few potential causes. First, ensure the unit is turned 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.
