Air Talk 900™ User’s Manual Rev D – 03/01/2007 FCC Statement This statement applicable for both the 5030 Wireless Audio Console and 5031 Wireless Lane Module NOTE: This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures: —Reorient or relocate the receiving antenna. —Increase the separation between the equipment and receiver. —Connect the equipment into an outlet on a circuit different from that to which the receiver is connected. —Consult the dealer or an experienced radio/TV technician for help. Understanding the Air Talk 900™ System Information and Basic Specifications The Air Talk 900™ is a wireless, full-duplex intercom system that supports any combination of 1 to 4 audio consoles communicating with 1 to 8 drive-thru lanes. Thus, the system can be as simple as 1 audio console communicating with 1 lane or as complex as 4 audio consoles communicating with up to 8 lanes. The audio quality of the Air Talk 900™ is superb because of advanced audio processing features such as background noise cancellation, echo cancellation, and RF compression / expansion techniques. Below are the basic RF technical specifications for the Air Talk 900™ wireless intercom:
Console Frequency: 925.5MHz (Tx), 904.5MHz (Rx) +/- 1.5MHz
Lane Frequency: 904.5MHz (Tx), 925.5MHz (Rx) +/- 1.5MHz
RF Channels: 20 at 150KHz spacing
Antenna Impedance: 50 Ohm
Line of sight range: 100 feet maximum The Air Talk 900™ consists of two basic modules; the 5030 wireless console and the 5031 wireless lane module. Both the 5030 and 5031 require only 12Vdc +/- 2.5Vdc to operate. No other wiring is required. Typical Installation Procedure The typical installation for the Air Talk 900™ is a very simple process consisting of the following steps: 1. Determine the desired number of 5030 consoles (1 to 4) and 5031 lane modules (1 to 8) 2. Setup a unique console number for each 5030 3. Connect power to the 5030 wireless consoles 4. Setup the lane numbers for each 5031 5. Mount the 5031 wireless lane modules 6. Mount the 5031 lane antennas and connect to the 5031 modules 7. Connect power to the 5031 wireless lane modules 8. Test the system and adjust as needed. Understanding the Base Frequency and Communications Frequency The Air Talk 900™ utilizes a base frequency for communications between the 5030 wireless audio consoles and the 5031 wireless lane modules while in the idle state. Every console and lane module communicates on this base frequency. When the wireless audio consoles and lane modules are in the idle state they are simply listening on the base frequency for commands. When a lane button is selected the wireless audio console sends a command requesting that the selected lane enter into a private communications session with the console. If the desired lane is present in the system and is listening on the base frequency the lane will acknowledge the command and both the wireless lane module and the requesting wireless audio console will switch to their own private communications frequency. All the other idle lanes and consoles will remain at the base frequency. When the teller hangs up or puts the customer on hold both sides will switch back to listening on the base frequency. The private communications frequency is determined by the unique audio console number setup. This is why the audio console number must be unique or the communications session between the teller and customer will not be private. Because so much communication occurs on the base frequency it is important that the base frequency be free from interference. Thus, there are 4 possible base frequency settings which may be tested and / or changed in the maintenance setup mode. See the section on Maintenance Setup for more information. Understanding the Master Lane Module As described above, when a teller and lane customer are communicating they are on a private frequency and thus are not privy to what is occurring on the base frequency. Thus, during this conversation the wireless audio console does not have access to the status of the other consoles and lanes and so the lane status LED’s on the console will not be updated. The purpose of the master lane module is to update the system status to an audio console that has been communicating with a lane and has hung up or put a lane on hold. In a system that has installed a master lane module every idle console will have an updated LED status. This may be important in a system with multiple tellers. In smaller installations it may not be necessary to have a master lane module because there may only be 1 or 2 tellers and the status of every lane is easily obtained without looking at the console LED’s. It is possible to enable or disable the use of the master lane module on a wireless audio console. If the use of the master lane module is enabled but not present there will be a 5 second communication delay after hanging up or putting a lane on hold before another button press will take effect. This is because the console is waiting for an answer from the master lane module. Thus, if a master lane module is not present it should be disabled in maintenance setup. See the section on Maintenance Setup for more information. Keypad Operation of the 5030 Wireless Console
