ABOUT THE I900SR
The I900SR is a powerful wireless A/V/S-Video signal sender and receiver system which
can be operated with satellite and cable receivers, camcorders, stereo systems, televisions,
laser disc players and VCRs, and provide superior reception at distances up to 60 Metres
(clear line of sight) from the transmitter.
This system can be used in many different ways:
● Enables you to watch a movie on any television within your home without moving your
VCR or Laser Disc Player, and without the hassle of running wires.
● Enables you to watch your favourite cable or satellite programs on any television in
your home.
● Extends the listening enjoyment of your stereo receiver to any powered speakers
in your home, even if they are not wired into your stereo system.
● Enables you to use your camcorder with a remote television as a closed circuit
monitoring system; ideal for baby's room, or for security.

USER GUIDE
1. Make sure your input AC voltage conforms to the adaptor specifications.
( Tolerance never more than 5%, such as 230 VAC +/- 10 VAC )
( With 230 VAC adaptor the input voltage can not be less than 220 VAC)
2. Only use the power adapter provided with the I900SR.
3. With direct line-of-sight, the maximum range of A/V signal transmission can reach up
to about 60 metres, and this distance would be shortened by obstacles or walls
placed between transmitter and receiver. (The optimum indoor range is under 25 metres
-penetration may vary depending on composition of walls, doors and floors)
4. To ensure good infrared remote control operation aim your remote control at the I/R
Sensor Window on the I900SR and press the buttons firmly. ( With some remote
controls it may be necessary to press and hold each button for about a second). The
working angle of the I/R Sensor Window is +/- 15 degrees. (see Pictures 7,8,)
5. The remote controller has to be used within the distance of ( from remote control
to receiver )not less than 0.3M and no more than 5M (working angle +/- 15 degrees).
(see Pictures 9)
6. Be sure the ON / OFF switch on both the transmitter and receiver is in the OFF
position before making any connections.

TRANSMITTER
Connect main signal source
a. By Composite Video(RCA)
1. Take a RCA to RCA cable (included),take one end connected to the AV In socket of
transmitter, matching up the colours from unit to cable…e.g. Red to Red, White to
White etc…(see Pictures 1-1 )
2. Connect the other end to the Audio / Video Out port of VCR, DVD, VCD,
Satellite receiver or CATV STB matching up the colours from unit to cable…e.g. Red to
Red, White to White etc…(see Pictures 1-1 )
RECEIVER
a. by Composite Video (RCA)
1. Take a suitable RCA to RCA (included) cable and connect one end to A/V socket of
Receiver, matching up the colours from unit to cable…e.g. Red to Red, White to
White etc…(see Pictures 3 )
2. 2. Connect the other end to the Audio / Video In port of TV, matching up the
colours from unit to cable…e.g. Red to Red, White to White etc (see Pictures 3 )
TROUBLE SHOOTING
No picture or sound
a) Check the power on/off switches on the Transmitter, Receiver and TV
b) Make sure the power plug and signal cables are pushed all the way in.
c) Make sure that all cables are connected as per the user guide
d) Check if there is any discontinuity inside the cable.
Interference & noise
a) Adjust receiver unit direction for optimal performance. (see Pictures 5, 6)
b) Adjust transmitter unit direction for optimal performance. (see Pictures 5, 6 )
c) Check if the supplied voltage matches the adapter specification
( With 230 VAC adapter the input voltage can not be less than 220 VAC)
(The power output has to be 9 VDC, 300mA centre positive)
d) If using a microwave oven, turn it off.
h) Remove microwave oven or clear unnecessary obstructions from the path
between transmitter and receiver.

1) To ensure good infrared remote control operation aim your remote control at the I/R
Sensor Window on the I900SR and press the buttons firmly. ( With some remote
controls it may be necessary to press and hold each button for about a second). The
working angle of the I/R Sensor Window is +/- 15 degrees. (see Pictures 7,8,9)
2) Check the path between the transmitter & receiver and clear unnecessary
obstructions.
4) Make sure the IR extender mouse is pointing toward the sensor precisely, or just
above the remote sensor window of the unit you are trying to control.
5) Check if the batteries on remote control are full of energy. Replace with new
batteries if necessary .
