SAFETY RULES FOR CHARGER
IMPORTANT SAFETY INSTRUCTIONS
1. SAVE THESE INSTRUCTIONS - DANGER: TO REDUCE RISK OF FIRE
OR ELECTRIC SHOCK CAREFULLY FOLLOW THESE INSTRUCTIONS.
This manual contains important safety and operating instructions for the GD200B garage door opener.
2.
Before using garage door opener, read all instructions and cautionary markings on garage door opener, battery,
and product using battery.
3.
CAUTION:
To reduce the risk of injury, charge only lithium-ion rechargeable batteries. Other types of batteries
may burst, causing personal injury or damage.
WI-FI COMMUNICATION INFORMATION
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.
