Introduction
Congratulations on purchasing the DigiSender® ZX7 - Quad Input 5.8GHz Wireless AV Sender. This
product represents state of the art wireless audio and video technology and the most advanced

the worry of interference from wireless routers, Bluetooth devices and other wireless products. It
also incorporates our advanced DigiEye™ remote relay technology allowing flawless operation with
every set top box ever made.
Bene it rom 5.8GHz transmission, 4 Inputs, 4 Audio/Video Channels, 16 Remote Relay
Channels and unsurpassed compatibility with the new DigiSender® ZX7!

Mount the I Emitter vertically using acces-
sories 1 and 2. Ensure the ED is facing the
remote control pick up point on your source
equipment.
Mount the I Emitter horizontally using the sup-
plied sticky pad. Ensure the ED is facing the
remote control pick up point on your source
equipment.

Using the DigiSender® ZX7
Advanced Functions
Changing the Audio/Video Channel
The DigiSender® ZX7 features 4 Audio/Video Channels. Each of these Audio/Video Channels slight-
ly changes the frequency on which the DigiSender® ZX7 operates. Because the Audio/Video Channel
switch allows you to ‘fine tune’ the frequency on which your DigiSender® ZX7 operates, it is possi-
ble to overcome most interference and reception troubles that may occur.
To change the Audio/Video Channel on your DigiSender® ZX7, simply change the position of the
Audio/Video Channel switches to match below.
For your DigiSender® ZX7 to unction correctly it is very important that the Audio/Video Channel
settings are the same on both the Transmitter and Receiver and that only 1 switch is down at
any time.
Changing the Remote Relay Channel
The DigiSender® ZX7 combines our advanced DigiEye™ technology with the IR Systeme Technik™
Remote Relay kit and features 16 digital Remote Relay Channels.
To change the Remote Relay Channel on your DigiSender® ZX7, simply change the position of the
Remote Relay Channel switches. Any combination of up and down switches can be used.
For your DigiSender® ZX7 to unction correctly it is very important that the Remote Relay
Channel settings are the same on both the Transmitter and Receiver.

Troubleshooting
Picture Problems
Q: W at do you see on your second television?
The picture is present but
poor quality
I still see a Black Screen...
WRONG AV C H A N -
NEL SELECTED
1. Switch the Transmitter back
on.
2. Ensure the correct SCART
channel is selected on your sec-
ond television. Some televisions
feature multiple AV channels for
one or more SCART, phono and
S-Video inputs.
3. If available try another SCART
socket on the second television.
POOR RANGE
1. The picture & sound quality is
affected by the Transmitter and
Receiver’s location. Try position-
ing them in different locations.
The Transmitter and Receiver
should be connected to a mains
extension lead that can be
moved.
2. Try the other 3 available
Audio/Video channels ensuring
that the Audio/Video Channel
setting is the same on both the
Transmitter and Receiver.
3. Ensure the units are within
the usable range, normally this
would be 40m when passing
through 2 average internal
walls. Thicker or stone/granite
walls may lower the usable
range of this device.
RECEIVING BLANK
SIGNAL
1. Switch the Transmitter on.
2. Ensure the Transmitter is con-
nected to your source device
(such as your Satellite, Cable,
Freeview, DVD or VCR).
3. Ensure that your source
device is switched on.
4. Use the supplied DigiSender®
Remote Control to select the
correct Input. This can be done
at either the Transmitter or
Receiver.

3. Try the other 3 available
Audio/Video channels ensuring
that the Audio/Video Channel is
set the same on both the
Transmitter and Receiver.
I now see a Black screen
WRONG TV
CHANNEL SELECTED
This indicates that the correct
SCART Channel has NOT been

sion. Look for buttons on this tel-
evisions remote control which
could select the AV Channel
such as E T, AV, VIDEO, VCR,
AU , Channel 0 AND .
I still see a snowstorm or
blue picture
INTERFERENCE
This indicates one or more elec-
trical devices are interfering
with the DigiSender®. Make sure
the Transmitter and Receiver are
not directly on top of other elec-
trical devices. Try all 4
Audio/Video Channels on your
DigiSender® as one or more may
still be available. Visit
digisender.net or contact our
helpline for information on con-
figuring your equipment to work
together.

Troubleshooting
Audio Problems
Q: W at seems to
be t e problem
wit t e sound?
I can see the picture but
can’t hear anything.
The sound is distorted.
There is a buzzing sound
present. It seems to get
worse during on-screen
menus or bright pictures.
1. Disconnect both the Transmitter
AND Receiver SCART cables.
Reconnect the cables ensuring they
are pushed into the sockets firmly.
2. If you are using a home cinema
DVD player with surround sound,
please ensure the analogue audio
output on SCART is switched on.
Turn down the volume on your
source device (Satellite, Cable,
Freeview, DVD or VCR).
Change the Contrast A/B setting on
the Transmitter DigiConnector™
connected to the offending equip-
ment.
There is a hissing sound
and the volume must be
turned up high on the
second TV to hear any-
thing.
1. Turn the output volume UP (if
possible) on your source device
(Satellite, Cable, Freeview, DVD or
VCR).
2. Ensure the Transmitter and
Receiver are within the usable range
(40m avg).
3. Switch off your microwave oven if
present.
