This transmitter is a two-channel device. Pressing the left button on the transmitter will send a channel one signal. Pressing the right button on the transmitter will send a channel two signal. The buttons feature raised dimples for easy, or vision-impaired identification. The transmitter has a red test/operate indicator and is powered by a 12-volt battery. A molded-in hole in the case is for attaching the transmitter to a key ring.
