Operates in the 27MHz band, the KEY series achieves the highest possible standard of performance by using a crystal-controlled, frequency modulated (FM) radio signal. The onboard microcontroller uses the latest technology allowing for easy setup and installation while providing maximum security and reliability.
The KEY ring transmitter uses a LED light to indicate a flat battery status. The 1Hz flashing of the LED indicates a flat battery. The blue LED light will be “on” when the transmitter is activated by simply pressing the button on the front.
The KEY ring transmitter uses a high capacity (150mAh) 6 volt battery instead of the usual low capacity (30mAh) 12 volt remote control battery. This allows the user to use longer lasting batteries for more reliable operation.

(Range tests were done in an open area test site with line-of-sight operation and no interference. The receiver antenna wire was fixed vertically, away from any metal objects.)
