OPERATION AND MAINTENANCE

IMPORTANT SAFETY INSTRUCTIONS
To reduce the risk of SEVERE INJURY or DEATH:
1. READ AND FOLLOW ALL INSTRUCTIONS.
2. NEVER let children operate or play with gate controls.
Keep the remote control away from children.
3. ALWAYS keep people and objects away from the gate. NO
ONE SHOULD CROSS THE PATH OF THE MOVING GATE.
4. Test the gate operator monthly. The gate MUST reverse on
contact with a rigid object or stop when an object activates
the non-contact sensors. After adjusting the force or the
limit of travel, retest the gate operator. Failure to adjust
and retest the gate operator properly can increase the risk
of INJURY or DEATH.

USING YOUR GATE OPERATOR

Your operator will operate with up to forty-nine Security✚
remote controls and one Security✚
If you purchase a new remote, or if you wish to deactivate
any remote, follow the instructions in the Programming
section.
Activate your operator with any of the following:
• The hand-held Remote Control (See Accessories):
Hold the large push button down until the gate starts to
move.
• The Keyless Entry (See Accessories): If provided with
your gate operator, it must be programmed before use.
See Programming.
When the operator is activated (with the safety
sensors correctly installed and aligned)
1. If open, the gate will close. If closed, it will open.
2. If the gate has been stopped in a partially open position,
it will close.
3. If obstructed while closing, the gate will stop and reverse
direction for approximately 2 seconds and then stop. The
next command will open the gate.
4. If obstructed while opening, the gate will stop and
reverse direction for approximately 2 seconds and then
stop. The next command will close the gate.
The operator alarm will sound under the following

board will require resetting. Reset the control board by
