Thank you for purchasing the d-force
TM
Overhead Garage Door Opener. Designed to
suit sectional overhead and one piece tilt up doors, the components and materials used
ensure this opener will provide years of simple and secure operation. Listed below are
some of the many features:
OPERATION
To open or close the door simply press a button on the hand-held remote transmitter or wall mounted
transmitter. During open and close cycles the door can be stopped by pressing the button again. The
next push of the button will reverse the door’s direction.
CODE HOPPING TECHNOLOGY
Every time a transmitter is used a new security code is randomly generated from millions of possibilities.
This greatly enhances the security of the system and makes “code grabbing” a thing of the past.
ELECTRONIC LIMIT DEVICE
Electronic Limits does away with manual adjustment of the door’s limits position.
SAFETY OBSTRUCTION SYSTEM
While the door is performing a close cycle, should it hit an obstacle or be restricted in some
manner, it will automatically reverse. The door will also stop if restricted whilst opening. The Safety
Obstruction Force should be checked monthly.
AUTO COURTESY LIGHT
The courtesy light comes on automatically for 2 minutes whenever the door is activated.
BATTERY BACKUP
The opener is fitted with a Battery Back-up kit for operation in the event of a power outage, or where
mains power access is not available. NOTE: If the door is the only entrance to the garage, and a
battery backup kit is not fitted, an Emergency Key Release System (E.K.R.) should be fitted externally
to the garage.
MANUAL OPERATION
The opener is equipped with a manual disengaging device. If the power to the opener is disrupted,
the door can be put into manual mode by pulling down on the Manual Release Mechanism string
handle at an angle towards the door. This allows for the manual operation of the door. To re-engage
the opener, pull the string handle away from the door.
