CHAPTER 1. Introduction
OUTLINE OF CHARACTERISTICS
The GMS340 series are remote control transmitter which uses CMOS technology,
and the EPROM version of GMS34XXX series.
This enables transmission code outputs of different configurations, multiple custom
code output, and double push key output for easy fabrication.
The GMS340 series are suitable for remote control of TV, VCR, FANS, Air-
conditioners, Audio Equipments, Toys, Games etc.
