Linear Megacode MDT-4A: 5-Channel Visor Transmitter

The Linear MDT-4A (part DNT00054A) is a 5-channel MegaCode visor transmitter on 318 MHz. It has four buttons on the front and a small Extra button on top. The four front buttons send channels 1 through 4 and the top button sends channel 5. Each unit is factory programmed with one of over 1,000,000 MegaCode codes, and the receiver learns each code, so the transmitter cannot be re-coded to gain access. It runs on two 2032 lithium batteries with up to 5 years of life, and the batteries are included. A high-visibility LED shows operation. A visor clip and a cover for the top button are included. Size is 1.6 in W x 4.2 in H x 0.8 in D.
