CHAPTER 7. GMS36XXXT
Description
The GMS36XXXT series are remote control transmitter which uses CMOS technology
and the EPROM version.
This enables transmission code outputs of different configurations, multiple custom code
output and double push key output for easy fabrication.
The GMS36XXXT series are suitable for remote control of TV, VCR, FANS, Air-conditioners,
Audio Equipment, Toys, Games etc.
