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 I9058D. If you use your own
adaptor, make sure the power output is 9V DC, 300 mA centre positive.
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 M)
4. To ensure good infrared remote control operation aim your remote control at the I/R
Sensor Window on the I9058D 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.

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) Check if the channel of transmitter & receiver are set to the same channel.
d) Make sure that all cables are connected as per the user guide
e) Check if there is any discontinuity inside the cable.
f) If you use S-Video connection, your TV set must be set to “S-Video” mode
Interference & noise
a) Adjust receiver antenna direction for optimal performance. (see Pictures 5, 6)
b) Adjust transmitter antenna 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) Select a different microwave channel by pushing the channel button on both
transmitter and receiver. (see Pictures 4 ) Make sure channel of transmitter &
receiver are set to the same channel, if they are try using alternative (same on both
units) channels until clearer reception is found.
e) You can also vary the transmitter / receiver position for optimal performance.
f) If the distance between receiver and transmitter is less than 10 M do not open
the antenna as the signal could be too strong to obtain a sharp picture.
g) If using a microwave oven, turn it off.
h) Remove microwave oven or clear unnecessary obstructions from the path
between transmitter and receiver.

For any further assistance, please contact:

1. Not Synchronised
2. Screen unlocked
3. Noisy line across the screen
a) Adjust receiver antenna direction for optimal performance.
(see Pictures 5, 6)
b) Adjust transmitter antenna direction for optimal performance.
(see Pictures 5, 6 )
c) Check if the supplied voltage matches the adapter specification.
d) Select a different microwave channel by pushing the channel button on both
transmitter and receiver. (see Pictures 4 )
e) If using a microwave oven, turn it off.
f ) Remove microwave oven or clear unnecessary obstructions from the path
between transmitter and receiver.
g) Move transmitter and receiver closer. If the problems remain, please contact
your vender for help.
Remote control extender does not work
1) To ensure good infrared remote control operation aim your remote control at the I/R
Sensor Window on the I9058D 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 is pointing toward the sensor precisely.
5) Check if the batteries on remote control are full of energy. Replace with new
batteries if necessary .
6) The optimum indoor operating range is about within 15 M.
