Before You Connect with Your Smartphone
Monitor and control your garage door from anywhere using the myQ® App.
You will need:
•Wi-Fi® enabled smartphone, tablet or laptop
•Broadband Internet Connection
•Wi-Fi® signal in the garage (2.4 GHz, 802.11b/g/n required)
•Password for your home network (router's main account, not guest network)
TEST THE WI-FI®SIGNAL STRENGTH
Make sure your mobile device is connected to your Wi-Fi® network. Hold your mobile device in the place where
your garage door opener will be installed and check the Wi-Fi® signal strength.
Check Signal Strength. If you see:
Wi-Fi signal is strong.
The garage door opener will
connect to your Wi-Fi network.
Wi-Fi signal is weak.
The garage door opener may connect to your
Wi-Fi network. If not, try one of the options
below to improve the Wi-Fi signal:
No Wi-Fi signal.
The garage door opener will not be able to
connect to your Wi-Fi network. Try one of the
options below to improve the Wi-Fi signal:
• Move your router closer to the garage door opener to minimize
interference from walls and other objects
• Buy a Wi-Fi range extender
For compatible router specifications and help, visit support.liftmaster.com.
See page 36 to connect the garage door opener to a mobile device.
Check the Door
To prevent possible SERIOUSINJURYor DEATH:
•ALWAYS call a trained door systems technician if garage door binds, sticks, or is out of balance. An
unbalanced garage door may NOT reverse when required.
•NEVER try to loosen, move or adjust garage door, door springs, cables, pulleys, brackets or their
hardware, ALLof which are under EXTREME tension.
•Disable ALLlocks and remove ALLropes connected to garage door BEFORE installation and operating
garage door opener to avoid entanglement.
•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.
To prevent damage to garage door and opener:
•ALWAYS disable locks BEFORE installing and operating the opener.
•ONLY operate garage door opener at 120V, 60Hz to avoid malfunction and damage.
Before you begin:
1. Disable locks and remove any ropes connected to the garage door.
2. Lift the door halfway up. Release the door. If balanced, it should stay in place,
supported entirely by its springs.
3. Raise and lower the door to check for binding or sticking. If your door binds,
sticks, or is out of balance, call a trained door systems technician.
4. Check the seal on the bottom of the door. Any gap between the floor and the
bottom of the door must not exceed 1/4" (6 mm). Otherwise, the safety reversal
system may not work properly.
5. The opener should be installed above the center of the door. If there is a torsion
spring or center bearing plate in the way of the header bracket, it may be
installed within 4feet (1.2 m) to the left or right of the door center. See page 15.
