IRM-37xx SERIES

The Notice of Application: (IRM-37xx SERIES)

Transmission remote control signal consist of four parts: Encode Part, IR Transmitter Source, IRM

device, Decode Part

1. When IRM-37xx SERIES code select frequency, it need to well understand the center system

of encode part.

2. Strong or weak light of IR Transmitter can affect distance of transmission.

4. It needs to ensure the translation range of decode part if it is applied to the pulse-width range.

5. IRM-37xx SERIES can be applied to the high data codes, but against disturbance slightly

weak.

If the above items hardly assure of its application, it’ll cause NG(no good) message from the edge of

signal.
