But do they protect or help maintain your very important good will? Not if clerks and customers have to shout and growl and repeat themselves to be heard or understood. Norcon’s TTU-7 wirelessTalk-Thru Communicator is a 2-way, hands-free audio system that provides high-quality personal communication between people separated by security or isolation barriers. FEATURES • Clear 2-way hands-free voice communication. Avoids shouting, repetition, and misunderstanding. • 900 MHz digital intercom system provides highly security CD quality sound. • Simple installation with no wiring between desktop unit and window unit. • Special designed for the windows with sliding down gates. • Quality electronic design and engineering. • .Rugged, tamper-resistant materials. Anodized aluminum • Units available for ADA applications. • Headset jack equipped for using the optional headset. 1 HOW IT WORKS ... The Norcon TTU system permits hands-free, 2-way communication between the booth attendant and the customer. 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 th e 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 desktop’s 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. 2 4. The outside unit needs a 3” to 4” diameter cutout in the barrier. The rubber gaskets prevent slippage and protect the barrier surface. Refer to Fig 2: Remove the four (4) 6-32 assembly screws. c Remove the four (4) 8-32 mounting nuts from the mounting rods. d Separate the faceplate and ho using. Hold the faceplate over the partition opening. Take care to center the faceplate and align the lettering horizontally. Masking tape can be used temporarily to secure the faceplate to the outside of the partition. On the inside of the partition m ount the housing over the four (4) 8-32 mounting rods. Be certain to position the housing so that the battery charger jack faced down and the antenna is straight up. Fig. 1 3 Fig. 2 HOW TO USE THE TALK -THRU COMMUNICATOR 1. There is a DIP switch on the Printe d 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 f actory and ready to use. In case of the user has multiple units installed in the same room and found interference with each other, ch ange 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. Example of DIP switch setting DIP SW4 SW5 SW6 SW7 SW8 Desktop ON ON OFF OFF ON Window ON ON OFF OFF ON 4 PCB COMPONENT SIDE Fig. 3 3. Use the battery charger to charge the desktop unit and the window unit before used. The built-in battery charging control circuitry will monitor the charging automatically. 4. Turn the TALK and LISTEN volume controls completely counter clockwise. 5 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. . 6 Operation Hints 1. When the battery is being charged, the dual color…

FCC ID: X7STTU7W Applicant：Norcon Communications Inc. Operation Description The heart of the unit is U10, SOC RF transceiver, which acts as audio encoder/decoder. The main clock of the system is 26MHz which is produced by the external crystal (26MHz) and internal oscillation circuit in U10. Analog audio is converted to digital audio by U6, TLV320AIC26. The digital audio data is then fed to U10 for voice compression. The compressed voice is transmitted to the other wireless unit by means of RF media. At the other end, the received data is decoded to digital audio data and fed to U6. Analog audio is then reproduced in the output of the U6. U7 is audio PA for further power amplification up to 2W. In the application program, the system control the talk side (mic input) and listen side (speaker output) according to different operation mode. The state of operation mode is determinate by the output of VOX detector (U5). Assurance the system can start-up safe, Reset IC (U13) is used. It guarantees all IC will be reset only if the operation voltage from LDO U3 reach 2.7V. The LDO U1 is used for analog voltage and LDO U2 is used for U6. U4 controls the charging current and voltage of the system operation battery. D12 (SS14) is used for reversed voltage protection. Two buttons are used for power and volume control. The antenna used with Reverse Polarity SMA connector. Common grounding on PCB is not connected to real external ground. Power supply is DC 4.8V by NIMH battery pack.
