1. READ AND FOLLOW ALL WARNINGS AND INSTRUCTIONS.
2. ALWAYS keep remote controls out of reach of children.

IMPORTANT SAFETY INSTRUCTIONS

9. After ANY adjustments are made, the safety reversal system
MUST be tested.
10. Safety reversal system MUST be tested every month. Garage
door MUST reverse on contact with 1-1/2" (3.8 cm) high
object (or a 2x4 laid flat) on the floor. Failure to adjust the
garage door opener properly increases the risk of SEVERE
INJURY or DEATH.
11. ALWAYS KEEP GARAGE DOOR PROPERLY BALANCED (see
page 3). An improperly balanced door may NOT reverse when
required and could result in SEVERE INJURY or DEATH.
12. ALL repairs to cables, spring assemblies and other hardware,
ALL of which are under EXTREME tension, MUST be made by
a trained door systems technician.
13. ALWAYS disconnect electric power to garage door opener
BEFORE making ANY repairs or removing covers.
14. This operator system is equipped with an unattended
operation feature. The door could move unexpectedly. NO
ONE SHOULD CROSS THE PATH OF THE MOVING DOOR.
15. DO NOT install on a one-piece door if using devices or
features providing unattended close. Unattended devices and
features are to be used ONLY with sectional doors.
16. SAVE THESE INSTRUCTIONS.
THE PROTECTOR SYSTEM
When properly connected and aligned, the safety reversing
sensors will detect an obstruction in the path of the infrared
beam. If an obstruction breaks the infrared beam while the door is
closing, the door will stop and reverse to full open position, and
the opener lights will flash 10 times. If the door is fully open, and
the safety reversing sensors are not installed, or are misaligned,
the door will not close from a remote control. However, you can
close the door if you hold the button on the door control or
keyless entry until the door is fully closed. The safety reversing
sensors do not effect the opening cycle.
ENERGY CONSERVATION
For energy efficiency the garage door opener will enter sleep
mode when the door is fully closed. The sleep mode shuts the
garage door opener down until activated. The sleep mode is
sequenced with the garage door opener light bulb; as the light
bulb turns off the sensor LEDs will turn off and whenever the
garage door opener lights turn on the sensor LEDs will light. The
garage door opener will not go into the sleep mode until the
garage door opener has completed 5 cycles upon power up.
LIGHTS
The garage door opener light bulbs will turn on when the opener
is initially plugged in; power is restored after interruption, or when
the garage door opener is activated. The lights will turn off
automatically after 4-1/2 minutes. An incandescent A19 light bulb
(100 watt maximum) or for maximum energy efficiency a 26W
(100W equivalent) compact fluorescent light (CFL) bulb may be
used.
