VIII. Wireless Trouble-shooting
Wireless Signal
This monitor (Receiver) only can receive signals from transmitter box. Location and user
environment will influence signal transmission quality. So, in order to get a high performance signal,
choose a proper location to place the transmitter box.
Sometimes you will lose signal when watching TV. To overcome, Follow steps below:
First, check the power source and turn it off and on again. If the signal still can’t be received, please
make sure you are close enough to the transmitter. Environments bad for signals are places such
as basements, hollow areas, building corners or places simply too far away.
Using Wireless TV uses 802.11a/b/g wireless transmission specification to transports signals with
2.4GHz & 5GHz frequencies as defined by IEEE. Signals transmitted out over 30 meters should be
supported. Unfortunately, there are too much wireless equipment in houses that can affect signal
transport quality.
Factors affecting transmission include microwave ovens or other high frequency electromagnetic
waves. Reinforced concrete walls, large-scale metal products and metal furniture should not be
located near machine. Water creates an obstacle and should not be placed near the machine.
Human bodies such as a person passing through the signal can cause poor signal quality.
How to improve the wireless signal quality?
Remove all obstacles that might reflect the signal. This could include furniture, cabinets, and walls. If
a user feels the wireless signal is not good enough, place the receiver at a new angle or readjust its
position to make an improvement.
Wireless Channel Selection
When the signal quality is bad the monitor will show the message “WIRELESS
OVERLOAD” or show state of constant searching.
The problem reason analysis:
The Wireless Displayer and transmitter use 802.11a/g to communicate with the transmitter
box, which includes channels 01, 3, 5, 7, 9, 11, 36, 40, 44, 48, 52, 56, 60, 64, 149, 153, 157
and AUTO. Channels 01 ~ 11 use 802.11g of 2.4G, Channels 36 ~ 157 use 802.11a of
5.8G.
When use at home, the use of channel 1-11, frequency 2.4G is recommended, and 2.4G
transmits longer distance than 5.8G. But when more interference exists in the surrounding
from similar equipments using 2.4G, the use of 5.8G is suggested. For example, the
existing large amount of blue tooth equipment disturbance on show site will affect 2.4G, if
you change to 5.8G, i.e, channel 36-157, which is less used, the disturb will be weaker,
there will be no such problem.
So, to improve signal quality we can change the wireless channel.
The change of wireless channels can be done directly by setting the monitor while it is
connected with the transmitter, the steps are as follows:
1
Touch the
“enter”
button on the monitor to see current channel displaying.
2
Touch down or up key to select a channel you think is better.
3
Touch
“source”
to confirm channel selection.
