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.3. CONTROL ELEMENTS4. OPERATION(1)   (4)   (3)   (2)
  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:3. CONTROL ELEMENTS4. OPERATIONNote: 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.3.

Fig 3 mute function onFig 2  mute function off 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 1.1VPL 1 indicates that the output  level is 575mVPL 2 indicates that the output  level is 250mV: This function is only  available when using the XLR  balanced output.Press the MENU key four  times and you will get  into the MUTE function. Use  the UP/DOWN keys to mute/unmute the  Unit. Press the MENU key five times and you will activate the SQUELCH function. To squelch or not to squelch, this is the issue...Squelch is a complicated name to express a simple conce pt: The threshold above or below that a signal is made pass through the receiver or not. Fig 1During 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.
