completely. Before permanently mounting the keypad, please program the keypad and test its


IMPORTANT: Your keypad may need to be hard wired due to the fact that it must accept

interference according to FCC regulations listed below. For example, applications

that are relativity close to cell towers or airports may receive intermittent interference and

require hard-wiring.

The GTO Digital Keypad is a multipurpose keypad that can work with other applications in

addition to GTO gate openers and locks. As a wired keypad it can operate garage door openers

and gate openers, that require 24 volts or less and accept normally open contacts.

As a wireless keypad it can be used with any gate or garage door opener that receives a 318

MHz RF signal. The keypad must be used in conjunction with the GTO garage door receiver kit

(part # RB709) on any other garage door.

SAFETY NOTE: Never install the keypad where a person can reach through the gate to activate

it, or where a person can touch the gate while activating the keypad. The recommended mini-

mum distance between the gate and keypad is 10 ft.

The manufacturer will not be responsible for any charges or damages incurred in the removal of the defective parts for repair, or for the reinstallation

Features of the Keypad

You may program up to 25 different personal entry codes, allowing you to give different entry codes to different users. For example,

you can give a delivery person their own entry code, which you can easily change after they have made the delivery. This will prevent

them from being able to regain access, while still allowing those to whom you gave other entry codes full access.

After entering a valid code, pressing any key while the gate is opening will stop the gate; pressing any key while the gate is stopped

and the gate will reverse direction. The keypad will not affect the auto-close setting of your gate opener system.

The keypad face will light up and beeper will beep at the press of any key. The keypad memory will recognize your entry code in a

string of up to 20 digits; if it finds the correct sequence it will activate the gate opener. As a security feature, the keypad will shut down

for 40 seconds if it does not find the correct code sequence within a 20 digit string. This will discourage an unauthorized person from

trying to use random numbers to access your property.

Your entry codes will remain stored in memory even when the batteries go dead. The keypad will remember your entry codes as long

as you don’t press the RESET button.
