What to do if my HemoCue Glucose 201 RT Blood Glucose Meter has no characters on the display?

If the HemoCue Blood Glucose Meter displays no characters, first, ensure the power adapter is correctly connected to both the AC power supply and the analyzer, and that the cable isn't damaged. If using battery power, replace the batteries with 4 type R6 or AA, 1.5 V batteries. If the issue persists, the display may be faulty, requiring service from your local distributor.
