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.
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.
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:

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.
