Unique circuitry facilitates ongoing, clear, 2-way conversation at all times as if the two parties were together in the same room. The TTU-7 wireless Talk-Thru Communicator includes window unit and desk-top unit, they both powered by high capacity rechargeable batteries. The desktop unit communicates with the window unit wirelessly. Both units are working at full-duplex mode, but the speaker is muted while the near end is talking. The desktop unit is always priority for talking; it interrupts the window unit and forces it to listen. The paired unit works on the same ID. The working channel is dynamically chosen according to the environment. If the present working channel is jammed, both units will jump to another channel. The system has 32 system IDs. 32 pairs of units can be installed closely without interference. In synchronous. The desktop unit automatically attenuates the outside channel. If the desktop unit is not used for a period of 30 seconds, the listening volume will be reduced approximately 70%. Normal operation is restored as soon as the attendant speaks into the desktops gooseneck microphone. The automatic volume attenuation circuit prevents outside noise from bothering the attendant. The TTU-7W provides clear communication even in environments with high ambient noise by shaping the sound for maximum intelligibility. The maximum distance between could be around 10 feet. HOW TO INSTALL 1. Mount the TTU window unit using the method shown in Figure (1). 2. The desktop is mounted on a marble base for stabilizing. PCB COMPONENT SIDE 2 5. Turn both window unit and desktop units on by switch power on off switch to center position. In this position the unit also in the auto mute mode. Adjust the TALK volume control until the attendant is clearly heard by the person outside the window when the attendant is speaking 2" to 4" from the gooseneck microphone at a normal speaking level. The green LED should go on when attendant starts talking and go off when the attendant stops talking. If the green LED stays lit constantly, it indicates either the TALK volume setting or the ambient noise is too high 6. window is clearly heard when you speaking at normal level. Make sure when speaking to the gooseneck microphone, the green LED above the TALK volume comes on and when stop talking the green LED comes off. Otherwise lower the TALK volume. Fig. 2 HOW TO USE THE TALK-THRU COMMUNICATOR 1. There is a DIP switch on the Printed Circuit Board (Fig.3). SW 4 to SW 8 is used for matching desktop unit and window unit. 32 system ID can be set to match the desktop and window units. TTU-7W is shipped with preset paired in the factory and ready to use. In case of the user has multiple units installed in the same room and found interference with each other, change the DIP switch setting to a different combination. Both the desktop unit and the window unit DIP switch must be set to the same position for matching purpose. 2.

Turn the TALK and LISTEN volume controls completely counter clockwise. 5 6 TROUBLESHOOTING You may occasionally encounter a problem with your TTU system. If this happens, refer to the following list. If additional help is needed, please contact us. 1. No sound at all Is the batteries being charged?

If the power supply has been plugged into a working outlet the battery charger indictor LED should be on, if it is not; the charger or the battery may be defective. 2. Howling ( Feed back) Is the TALK or LISTEN volume turned too high?
Set the volume control to a proper level. In most cases, both TALK and LISTEN should be set to the position of around 11 to 12 oclock. 3. Conversation cutting-off and breaking-up Is the TALK volume setting too high?
Turn down TALK volume to a proper level. Is the attendant speak too far to the gooseneck microphone?
The idea distance is 3 to 4 from the gooseneck microphone and the TALK indicator LED should come on while talking and come off while not talking. 8 Service Policy TALK-THRU SYSTEM WARRANTY REPAIRS Norcon Communications Inc. warrants the products Manufactured by Norcon to be free from defects in material and workmanship for a period of one year from the date of shipment from the factory provided:

When the battery is being charged, the dual color battery charge indicator is lit in RED; it turns green when the battery is fully charged. 2. Increasing the talk volume control allows the attendant to speak further from the gooseneck microphone as well as increasing the talk channel volume. The optimum distance from the gooseneck microphone should be maintained at approximately 3" or conversations not directed to customers may be heard outside the booth. 3. Install a headset into the headset jack will allow communications from the headset and disconnect the gooseneck microphone 4. The unit will decrease the incoming volume level by approximately 70% in about 30 seconds after the attendant speaking into the gooseneck microphone. The purpose of this feature is to decrease the amount of extraneous noise entering the booth when no one is at the booth. Normal volume level is restored when the attendant speaks into the gooseneck microphone. The muting function can be defeated by switching the AUTO MUTE switch to UTO MUTE OFF position. 6 TTU-7 wireless P.1 FCC STATEMENT 1. This device complies with Part 15 of the FCC Rules.
