Frequently Asked Questions

What is the operating voltage range for this module?

The recommended operating voltage (VCC) is between 2.7V and 3.6V.

What applications are suitable for the RPM7240-R series receiver?

It can be used for all household electric appliances such as TV, DVD, air conditioner, and audio equipment.

How does the device perform in outer light conditions?

The effective distance under outer light conditions is measured when the illuminance (Ee) is less than 10 Lux.

What must be set on the transmitter for correct operation?

The transmitter’s carrier frequency must be set to match the receiver’s $f_o$ frequency. Also, the recommended signal format should be used.
