WIRELESS KEYLESS ENTRY – MODEL SERIES 66 AND 740

FEATURES OF THE KEYPAD TRANSMITTER

Personalized Code: Up to 10,000 possible combinations.
Code can easily be changed if desired.

Operation:  Opener activates when 4-code digits and ENTER
button are pressed.

The Keypad Transmitter will open and close the door even if the
Door Control Lock Switch feature is ON. 

If wrong numbers are accidentally pressed, correction can be
made immediately. The ENTER key will transmit only the last
four digits.

The keypad will blink for 15 seconds after the code is 
transmitted. During that time, you can STOP or REVERSE door
travel just by pressing the ENTER key.

The keypad transmitter can be used with garage door opener
receivers having a yellow, grey, white or green “learn” button.
