KEYPAD

This digital keypad is a MegaCode series of wireless radio controls designed for use with automatic garage 
door and gate operators. The MegaCode radio format provides unparalleled security with more than a million 
different codes.
In operation, the user enters their unique code on the unit’s keypad (1 to 6 digits long) and presses 
the      button to activate the door operator. For up to 30 seconds after the last activation, the keypad can 
be re-triggered by simply pressing the      button again. This allows the user to stop or reverse the opener 
quickly, without having to re-enter their code.
The keypad has built-in keypad lighting for use at night or in dark areas. The clear silicone keys are backlit 
with a pleasing blue glow. By pressing the      button first, before entering their code, the user can light up the 
keypad.  Pressing the      button twice at any time will light up the keypad.
The keypad lockout timer will disable the keypad after 10 activations. The keypad must remain idle for 30 
seconds before new attempts.
MegaCode receivers are programmed by sending a signal from the user’s transmitters. This stores the 
transmitter’s code into the receiver’s memory. The receiver will retain its memory even without power and 
will only activate from these “memorized” transmitters. Each keypad code can be considered a different 
transmitter. Each MegaCode receiver can remember a maximum of 10 transmitter codes. Any combination of 
portable transmitters and keypad codes up to the maximum number can be entered.
