Safety and Product Care
With reference to unpacking, installation, use and maintenance of your electronic device, the following basic guidelines are
recommended:
Do not use or install this product near water to avoid fire or shock hazard. For example, near a bathtub, kitchen sink,
laundry tub, or near a swimming pool. Also, do not expose the equipment to rain or damp areas (e.g. a wet
basement).
Do not connect the power supply cord on elevated surfaces. Allow it to lie freely. There should be no obstructions in
its path and no heavy items should be placed on the cord. In addition, do not walk on, step on or mistreat the cord.
To safeguard the equipment against overheating, make sure that all openings in the unit that offer exposure to air are
unobstructed.
WARNING
Disconnect the power line from the device before servicing.
Transport and Handling
When transporting the 4GM3W, it is recommended to return the product in the original packaging. This ensures the product will
not be damaged.
In the event the product needs to be returned, ensure it is securely packaged with appropriate padding to prevent
damage during courier transport.

Installation and Configuration
of the 4GM3W
Placement of your 4GM3W
The wireless connection between your 4GM3W and your WiFi devices will be stronger the closer your connected devices are to
your 4GM3W. Your wireless connection and performance will degrade as the distance between your 4GM3W and connected
devices increases. This may or may not be directly noticeable, and is greatly affected by the individual installation environment.
If you have concerns about your network’s performance that might be related to range or obstruction factors, try moving the
computer to a position between three to five meters from the 4GM3W in order to see if distance is the problem.
Note: While some of the items listed below can affect network performance, they will not prohibit your wireless
network from functioning; if you are concerned that your network is not operating at its maximum effectiveness, this
checklist may help.
If you experience difficulties connecting wirelessly between your WiFi Devices and your 4GM3W, please try the following steps:
In multi-storey homes, place the 4GM3W on a floor that is as close to the centre of the home as possible. This may
mean placing the 4GM3W on an upper floor.
Try not to place the 4GM3W near a cordless telephone that operates at the same radio frequency as the 4GM3W
(2.4GHz).
Avoid obstacles and interference
Avoid placing your 4GM3W near devices that may emit radio “noise,” such as microwave ovens. Dense objects that can inhibit
wireless communication include:
Refrigerators
Washers and/or dryers
Metal cabinets
Large aquariums
Metallic-based, UV-tinted windows
If your wireless signal seems weak in some spots, make sure that objects such as those listed above are not
blocking the signal’s path (between your devices and the 4GM3W).
Cordless Phones
If the performance of your wireless network is impaired after considering the above issues, and you have a cordless phone:
Try moving cordless phones away from your 4GM3W and your wireless-enabled computers.
Unplug and remove the battery from any cordless phone that operates on the 2.4GHz band (check manufacturer’s
information). If this fixes the problem, your phone may be interfering with the 4GM3W.
If your phone supports channel selection, change the channel on the phone to the farthest channel from your
wireless network. For example, change the phone to channel 1 and move your 4GM3W to channel 11. See your
phone’s user manual for detailed instructions.
If necessary, consider switching to a 900MHz or 5GHz cordless phone.
Choose the “Quietest” Channel for your Wireless Network
In locations where homes or offices are close together, such as apartment buildings or office complexes, there may be wireless
networks nearby that can conflict with your wireless network. Use the Site Survey capabilities found in the Wireless Utility of your
wireless adapter to locate any other wireless networks that are available (see your wireless adapter’s user manual), and switch
your Router and computers to a channel as far away from other networks as possible.
Experiment with more than one of the available channels, in order to find the clearest connection and avoid interference from
neighbouring cordless phones or other wireless devices.
