1. INTRODUCTION
Thank you for your purchasing the AU-800 LTO wireless system.
Your AU-800 is based on a new revolutionary UHF PLL (phase loop locked) circuit
which allows the simultaneous use of more than 144 channels (depending on your
country regulations). The Receiver is provided with 2 antennas that constantly
monitor the incoming RF (radio frequency) signal and send only the stronger RF
signal to the AU-800R Receiver. Your AU-800 system is full of key features such
as AUTO-SCAN function, battery level monitoring and others.
Enjoy your AU-800 and make sure to read this Manual carefully before operation!
Depending on the options available your AU-800 system consists of:

Most countries closely regulate the radio frequencies used in the trans mission
of wireless information. These regulations state which devices can use which
frequencies, and help to limit the amount of RF(radio frequency)interference in all
wireless communications. To be flexible enough to operate worldwide, MOD-800R
Wireless receivers are available in a number of models, each with a unique
frequency range. Each frequency range, or band, spans up to 24 MHz of the
wireless broadcast spectrum. Available bands are:

You don't want accidental change of frequency or other setting in the middle of a
performance, do you? Any miss-operation during a live performance can be easily
avoided thanks to the LOCK function. With the LOCK function ON no further change
of setting is allowed until the Transmitter is unlocked. To access the LOCK Menu,
press the CH/ON key four times and then press the SELECT key to lock or unlock
the Transmitter Settings. Your choice of setting will automatically be saved into the
Transmitter in a few seconds. The blue display shows "lock" and "unlock" depending
on the operating mode.

Sometimes, there are things that you want to tell to your Friends on stage or
your nearby Companion during a Meeting but not necessarily to the rest of t he
world especially if you are ON LIVE on CNN... A smart feature on your Transmitter
allows you to easily MUTE the microphone so you are free to talk to the people
next to you without the rest of the world hearing what you say . To enter into
MUTE function simply press the SELECT key for a few seconds and the Transmitter
will mute any audio signal going to the Receiver. Press SELECT again for a few
seconds and you will UNMUTE the Transmitter.
With the rechargeable batteries put inside, use the charger supplied to

It is the detachable belt clip for easy carry during the live applications.
It is a flexible antenna. To get effective transmission, never cover the
antenna with hand, clothes, etc. during operation, and always position
the transmitter nearby the receiver.

Note: Why LTO wireless systems come with 144 different frequencies?
Not because you will need to use 144 different microphones at the same
time. It is unlikely that you will use more than 8 systems at the same
time so why 144 frequencies? This mainly depends on Countries regulations.
We offer frequencies from 470 to 900 MHZ. Some of these frequencies
are illegal in certain Countries and vice versa. Offering such a wide range of
frequencies we make sure that each single Country on the planet will
have more than enough choice of frequencies available. Not only: A
certain frequency is close to the frequency generated by lighting equipment,
a computer, a fax machine and so on. Therefore, thanks to the large
number of frequencies available you can easily switch to another frequency
that is interference-free.
In your Transmitter, there are 12 frequency bands or GROUPS. Each Group
contains 12 channels according to EMC regulations.
To select a Group you must first switch your Transmitter ON by pressing the
CH/ON key for a few seconds until you hear the beep and the blue display is
lighted. Then press the CH/ON key again slightly and you will access the GROUP
menu. At this point use the SELECT key to change the GROUP value from 1 to
12. Now, to access the CHANNEL menu, press again slightly the CH/ON key
two times and use the SELECT key to change frequency from 1 to 12. Your
setting will be automatically saved in a few seconds and the display will go back
to the main menu showing the operating frequency.
Once you have changed the operating frequency on your Transmitter,
you need to activate the SCAN function in your AU-800R Receiver. In this way,
the Receiver with synchronize automatically on the Transmitter frequency.
Your Transmitter can operate on three different levels of output power . These
are different from the Handheld Model and the Bodypack model.
For the Handheld model the levels are
- PL 0, the output power is 0 dBm
- PL 1, the output power is 5 dBm
- PL 2, the output power is 10 dBm
And for the Bodypack version the levels are
- PL 0, the output power is 0 dBm
- PL 1, the output power is 5 dBm
- PL 2, the output power is 10 dBm
position the transmitter nearby the receiver.
OK, if so far you remember all the functions and features of your AU-800
system you are ready to operate the Unit. Let's start from the Receiver:
A.This indicates the Frequency Group. There are 12 Groups and each
Group includes 12 different channels (frequencies).
B.This indicates the Channel Number. There are 12 channels for each one
of the 12 Groups for a total of 144 channels.
C.MUTE: If the Display shows , the Mute function is disengaged. If the
display shows , the Mute function is engaged.
D.This shows the selected frequency.
E.This shows you the remaining life of the Battery of your Transmitter. 3
segments means full life, 1 segment means it is time to replace or
recharge the battery. If this icon disappeared, it means
that your transmitter is switched OFF.
F. This bar(AF) indicates the level of the audio signal coming into the Re ceiver.
G.This bar(RF) indicates the level of radio signal coming into the Receiver.
H.This indicates which of the 2 antennas is operating. Radio signal will
automatically switch from Ant 1 to Ant 2, indicating that the diversity
circuit is operating properly.
- And now, let's see the four keys in detail:
MEM key: The first function of this key is to activate the AUTO-SCAN
function. Suppose that you have more than one LTO transmitter in
front of you with your AU-800R Receiver and you want to start to
operate one of them with your AU-800 Receiver.
First of all, you should turn your Transmitter ON, then with your
AU-800R Receiver turned ON, press the MEM key at least for
one second. Your AU-800R will automatically look for the frequency
where your LTO Transmitter is operating. It will scan all the 12
Groups and Channels for a total of 144 frequencies available.
4. OPERATION
3. CONTROL ELEMENTS
During this process, the audio output will be muted and the display will show
you the Group Number scanned, the channel number scanned and the
frequency that is being scanned. Once the transmitter frequency has been
found, the display will flash and the RF bar indicator and Battery life icon will
appear. Press MEM again slightly and such frequency will be stored into your
AU-800R Receiver. Please note that frequencies can be scanned manually
using the UP/DOWN key. See the Annex for more details.
This key activates several functions:
Press this key slightly once and you will get into the MANUAL SELECT for
the 144 frequencies. When the GROUP indicator is flashing, you can press
the UP/DOWN keys to select manually the desired Group. Then you can press
the MEM key to store this setting.
Press the MENU key twice and the CHANNEL indicator will flash. Use the UP/DOWN
keys to selected the desired channel and then press MEM key to store this setting.
Press the MENU key three times and you can adjust the OUTPUT LEVEL. Using
the UP/DOWN keys you have the choice to select three different levels:
PL 0 indicates that the output level is 1.1V
PL 1 indicates that the output level is 575mV

PL 2 indicates that the output level is 250mV
