1. When IRM-37xx SERIES code select frequency, it need to well understand the center system
2. Strong or weak light of IR Transmitter can affect distance of transmission.
3. Minimum Burst Length T
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
of encode part.
