Orienting Units for Optimal Performance
Placing:
Place the transmitter and receiver on a flat, stable surface to prevent damage from falling.
For optimal performance, try to place the units as high as possible to avoid any possible
interference from people walking between the transmitter and the receiver.
Microwave ovens can cause interference. Be sure you do not position the transmitter and
receiver with a microwave in the path between them.
Adjusting the Audio/Video Antennas
For optimal reception, the antennas on both
transmitter and receiver should be oriented. In most CWV“ Fa“
situations the curved face ofthe audio/video antennas
on both the transmitter and receiver should be facing
each other. Since all operational environments are
different, additional slight tilting and twisting may be
necessary. Ifthe transmitter and receiver are less than
10 feet (3 meters) apart, keep the audio/video antennas
flat in their casings.
Curved Face

Orienting Units for Optimal Performance
The audio/video antennas have been designed to pivot but have limited rotation in
either clockwise or counterclockwise directions. Antenna does not rotate freely 360
degrees. Rotating past the point where resistance is felt will result in permanent
damage to both antenna and mechanical stopper.
The GigaAir 2020 Receiver's built in auto—sequence function is ideal for security use. You can
purchase additional GigaAir 30T/40T wireless cameras with built-in transmitter to monitor
and transmit the image and sound to the receiver.
The receiver can be used with up to four cameras on four different channels and display them
in sequence on a single TV/monitor. The receiver's various operating modes are set via
dipswitches as shown in the following diagram:
Factory-preset Mode
Dipswitches 1 ~ 4: Set up the automatic channel sequence function
Slide the channel dip switch that you wish to view to the ON position.
Dipswitch 5: Sets the sequence change interval time
ON:Changes channel every eight seconds.
OFcmhanges channel every four seconds.
—————————-—-——
Auto-Sequence Function for Multiple Location Monitoring
Note 1: The Receiver will auto detect the receiving channels, and display them in
sequence. When only one channel dip switch is in the ON position, the
receiver will receive the channel continuously, without regard to the position
ofthe 5th dipswitch. Ifmore than one clip switch remains on, the auto-
sequence function will continue on those channelst
Note 2.- When none ofthe dip switches are in the ON position, the receiver will
automatically set the receiving channel to Channel 1.
Exa mple:
Using the auto-sequence function:
If you have two wireless camera (GigaAir 30T/40T) and their
channels are set on CHANNEL 1 and CHANNEL 3, and you wish
to monitor the two channels in sequence, you must slide up the
first and third dip switches to the ON position (see the diagram
on the right). Ifyou wish these two channels to he alternated at
eight-second intervals, slide the DIP 5 switch to the ON position
Leave it in the lower position for four-second channel change
intervals. ’
Stopping the auto-sequence function:
To stop the auto-sequence function and lock on one channel, leave the dip switch for the
Channel you want to receive in the ON position. Slide the others to the lower position.

Troubleshooting
iii If you are not getting any signal at all
0 Check that the transmitter and receiver are properly connected to the
audio/video components from which you want to send/receive the audio/video 5
signal
4 Make sure that the transmitter is connected to the surce device and the receiver
to the receiving device
0 Check the power ON/OFF switches on the transmitter and receiver
0 Check power switches on the remote TV and video source (VCR, laser disc
player, satellite receiver, etc.).
0 Make sure power plugs are pushed all the way in.
0 Check all cable connections.
0’ Check the CHANNEL switch on both transmitter (GigaAir 10T) and receiver
are set to the same number
0 lfyou connect the receiver to a TV through an RF modulator, check that the TV
is tuned to the same channel as the TV Channel switch on the RF modulator (3
or 4)
Troubleshooting
iii If the signal is poor, or there is interference
0 Adjust the antennas orientation (see "OrientingUnits for Optimal
Performance", on page 24).
9 Change the channel on both transmitter and receiver and make them the
sametRcmove microwave oven from the path between the transmitter and the
receiver
9 Make sure the transmitter and receiver are within range (up to 300 feet)
0 Check the channel dipswitch positions on the receiver
