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.
