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.
