Chapter 1. GMS36XXX
1. GMS36XXX
Description
The GMS36XXX series are remote control transmitter which uses CMOS technology.
This enables transmission code outputs of different configurations, multiple custom code
output, and double push key output for easy fabrication.
The GMS36XXX series are suitable for remote control of TV, VCR, FANS, Air-
conditioners, Audio Equipment, Toys, Games etc.
