Introduction

OUTLINE OF CHARACTERISTICS

The GMS340 series are remote contol 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 GMS340 sereis are suitable for remote control of TV, VCR, FANS, Air conditioners, Audio Equipments, Toys and Games etc.
