The Dolphin Wireless Keypad is a weather-resistant keyless entry station transmitter. Entering a programmable 4-digit access code sends the programmable radio code to the receiver to activate the door or gate operator. The keypad is powered by a 9-volt battery, with low battery indicator. When the battery gets low, the keypad will blink during use to indicate that the battery needs changing. The keypad has 1,024 possible radio codes. The keypad will only activate receivers set with the same code programmed into the keypad.
