Operating Range
The remote control uses infrared (IR) transmission to control Qumi. It is necessary to point the
remote directly at Qumi..
The remote control functions properly within a radius of approximately 7 meters (23 feet) and
15 degrees above or below the Qumi level (If the remote is not held perpendicular to the sides
or rear of Qumi).
If Qumi is unresponsive to the remote control, move closer towards Qumi.
