Use and Care Manual

Your garage door opener can be operated remotely on 
the smartphone app.
The communication distance (range) between your 
garage door opener and your Wi-Fi router may be 100 
feet (30 meters) inside your home. A number of factors in 
and around your home may reduce this range including 
the number of floors, number/size of rooms, furniture 
and types of building materials used for construction.  
Examples may include suspended ceilings, ductwork, 
large metallic appliances (refrigerators) and metal studs.  
Interference from these factors in your home can be 
overcome by adding Wi-Fi signal boosters to extend the 
range of the wireless signal from your router in your home.
NOTE:
1.The range and proper operation of any wireless device 
will vary depending on factors in and around your home. 
2.Your garage door opener may not transmit between 
buildings. If you have a detached garage, your garage 
door opener may not communicate properly with your 
Wi-Fi router.
3.Metal objects (e.g. wall studs) and metallic wallpaper may 
interfere with the signal from your Garage Door Opener.  
You will need to test your Garage Door Opener after any 
changes to your home or garage including remodeling, 
moving furniture and installing new appliances or devices 
that communicate with your Wi-Fi router.
NOTICE:
It is important that the wireless signal from your router is 
secured. An unsecured signal could allow unauthorized 
access to devices communicating on your home network 
including your garage door opener. 
Since the 1990s, security algorithms have been used 
to encrypt and protect wireless signals. The two most 
commonly used algorithms are WEP and WPA/WPA2.
•  WEP (Wired Equivalent Privacy) is the oldest and most 
widely used security algorithm. Despite its popularity, 
this algorithm is the most susceptible to hacking. The 
network passwords used to protect WEP networks 
have to be exactly 10 or 26 characters long and 
can only include hexadecimal characters (a-f and 
0-9). By modern standards, passwords with these 
limitations are not complex enough to offer adequate 
security. In 2005, the Federal Bureau of Investigation 
demonstrated WEP’s vulnerabilities by easily cracking 
WEP passwords using publicly available software.
  Due to serious security concerns, your garage 
door opener will not connect to routers using WEP 
network security. Refer to your router’s operator’s 
manual to change the security type to WPA/WPA2.
•  WPA/WPA2 (Wi-Fi Protected Access) was created 
as a safer alternative to WEP. The cryptographic 
technology in this algorithm is far superior to that of its 
predecessor. WPA/WPA2 passwords can be up to 63 
characters long and include hexadecimal characters 
as well as any printable ASCII characters (a-z, 0-9, 
punctuation marks, and some glyphs). Although it 
offers greater protections, WPA/WPA2 networks can 
still be vulnerable if weak passwords are used. Always 
use a strong password that includes upper and lower 
case letters, punctuation marks, numbers, and glyphs 
(if supported) to reduce the risk of the password being 
cracked or guessed by unauthorized parties.
