Introduction - RX6 Receiver
The RX6 is a 16 channel stereo UHF radio receiver designed as part of the Audeon wireless audio system. It receives freque ncy modulated rad io signals with Zenith- GE stereo encoding in the 864 MHz ISM band and in TV channel 69 (854 MHz to 862 MHz). Production of the RX6 receiver commenced in June 2005.
The RX6 has facilities to enable the installer to reassign the channel frequency allocation and to reduce the number of available channel s which are received. Thi s new facility will allow the reception of signals from the single channel transmitters where the frequency allocation requires non harmonically related carriers.
Operating the receiver
Connect a suitable pair of headphones to the 3.5mm jack socket. Switch the receiver on by turning the on/off switch and volume control clockwise. The display will be illuminated and the message “H E L L O” will be displayed followed by a “1" indicating the first channel to be selected. Rotation of the volume control will increase the sound in the headphones. Avoid increasing the volume control before wearing the headphones as the program content may be very loud and uncomfortable.
Installation of the system
Initial testing
After the successful installation of the transmitter (see appropriate instructions for either the MCTX or the SCTX), test the reception with an RX6 receiver. All the r eceivers are despat ched from the factory fully charged, so a walkabout test can be performed throughout the venue before they are attached to a machine. Check for range, weak signal strength and dead sp ots. Any problems at this stage should be addressed and the transmitter

aerial re-sited if require d. You should expect to have a minimum 90% cove rage in most venues but metal pillars and similar objects which are in direct line of sight will obstruct the radio signals
Installing the Receivers
The receivers are supplied with the internal jumper link set to 8 channel operation unless the installer has requested a different frequency plan. The PIC microcontroller which is inside the receiver has the software version indicated on it s label and it is also di splay ed following th e “HELL O” message. Before connecting to the power supply check that the receiver works correctly.
Changing the number of channels from the standard 8 channel frequency plan to the standard 16 channel plan can be done either in hardware or software.
Changing the Frequ ency Plan in the H ardware
To change from the standard 8 channel to 16 channel operation, open the receiver by unscrewing the two small pozi drive screws, then the case can be gently pulled apart to reveal t he electronic PCBs. The main receiver PCB designated RX610 has the volume control with the jumper link (JP1) adjacent to it . Move the jumper link down so that the two pins are not connected then fasten the two halves of the receiver back together making sure that the boards locate together correctly. Test the operation of the receiver before connecting it to the charger & power supply.
Entering the Software Programming Mode
Upon switch on of the receiver the installer will need to access the programming mode by holding down the channel select switch whilst the HELLO message is displayed until the flashing letter “P” appears. After displaying the letters “H E L L O” followed by a “1” (the software version) a flashing letter “P” (for programming mode) will be display ed. The receiver is now in programming mode and the letter “A” is display ed. Pressing the channel select button will cycle through the three menus “A” “L” and “C”. Holding the channel select button down whilst one of the letters is displayed wi ll allow the installer to select options from that m enu.
Selection of the required frequency plan is achieved by using one of the three menus.
Menu “A” Alternate Frequency Plan
Selecting this menu will enable the installer to easily select a number of popular pre defined frequency plans. These are des igned for the lo west intermod when using single channel transm itters in an installat ion. Please note that to avoid crosstalk and intermodulation we do not recommend using single channel transm itters on more than 4 frequencies within the licence free band (863MHz to 865 MHz). The frequency assignments for these plans are shown in appendix ii.
When “A” is displayed hold the channel select button down until “-” is displayed, release the button a nd a “1” is now displayed. To select this as the requir ed frequency plan press the channel select button until “F” (finish)

is displayed. The plan for selection 1 has now been wri tten to the EEPROM al ong with the last channel num ber to be displayed (in this case a 1. Switch the receiver off and the new frequency plan will be effective when the receiver switche d on. Do not hold the chan nel select but ton down on whilst HELLO is displa yed unless y ou wish to re-enter the programming mode.
The selection can be easily changed back to the standard frequency plan using menu “C” (see “C” to clear selection), or reprogramm ed with an alternat plan “A” or placed in learn mode “L”. To select a new frequency plan from those in appendix ii proceed as above. On switch on hold the channel select button down until “P” flashes, select “A” and hold until the “-” appe ars. Now select the required new frequency plan. This time choose the 4 channel plan which will reallocate the standard frequencies allocated to channel s 1, 3, 6 and 8 to a new plan where they will be channels 1, 2, 3 and 4. Press the channel select button until “4” is displayed, then hold the button down until “F” for finish is displayed. The EEPROM has now been updated with the new plan, the number of channels selected has been saved as 4 and the flag has been reset for frequency plan no 4.
Menu “L” Learn a new plan
This menu will allow the installer to create a frequency plan to suit the venue. Sometimes frequencies are required in TV cha nnel 69 and others in chan nel 70. This is often the case where radio micr ophones are in use on the same site. Hold the selector button down when “L” is displayed until the “-” is displayed. Release the button and “1” is displayed. Frequencies which are not r equired are deleted from the freque ncy plan so assuming that frequencies allocated in the standard frequency plan (appendix i) for channels 2, 4 and 16 are to be deleted press the selector button once so t hat “2” is displayed. Now press the button until “E” (erase) flashes. When the “E” stops flashing the next channel number (3) will be displayed and the receiver has removed channel 2 fr om the frequency plan. The number 3 is now showing on the display , you require this frequency so press the button once so that the number 4 is displayed. Channel 4 is not required so press the button until “E” (erase) flashes. When the “E” stops flashing number 5 will be display ed. Channels 5 to 15 are re quired so press the button once for each of these. At channel 16 whic h is not required hold th e button down until “E” fl ashes. When “E” stops flashing the number 17 will be displayed for a short time followed by “F” (finish). The new frequenc y plan has been written to the EEPROM, the last channel number has been set for the new total of required channels and the flag has been set inside the receiver to indica te that a new frequency alloca tion has been set. Turn the receiver off, then switch it on again to check the new frequency plan. You will have a total of 13 channels which have been reallocated to the frequencies which were not deleted in ascending order.
To change the channels to a different plan repeat the above learn mode “L” or use the allocation mode (A) or the clear mode to return to the standard frequency plan.
Menu “C” Clear selections
This menu allows the installer to quickly reset the channel frequency plan to the standard frequency plan. Hold the selector button down whilst “C” is displayed unti l “-” is displaye d. Release the button and “F” (finish) is displayed. The EEPROM has been reset t o the original settings. Swit ch the receiver off and when you switch it on again the original factory settings will be restored.

Other facilities
Hours Used Counter
The receiver will record the total time that the unit has been operating which is useful for service and determining the battery life. We estimate that the battery life is in the order of 10,000 hours but there is insufficient data to be certain. Aft er 10,000 hours use the display will change on start up to show a patt ern before the “HELLO” message and “H” will be displaye d after the hello m essage. After 12,500 hours of use a “U” will be displayed following the “H”. These displays will not affect the operation of the receiver when in use but do indicate that a service is required. When the batteries are replaced the hours counter will be reset as pa rt of the service. The hours counter can count up to 640,000 hours!
Switch On Counter
This counter will record the number of times the receiver has been switched on so that we can deter mine how much use the receiver has had. It can only be read at the factory during a service.
Headphone Disconnect Counter
This counter records the number of tim es the headphones have bee n removed when the rec eiver is switched on. Like the Switch On Counter above it will provide information on the receivers use and can only be read at the factory.
40 Minute Timer
The information for this timer is stored in the EEPROM and the timer can be changed so that the receiver will run for up to a maximum of 80 minutes before switch off. This timer can only be changed at the factory.
Software Version
The current software version is indicated following the “HELLO” message. For version 1 software a “1” is displayed so you may not notice this before the first channel is displayed.
Fastening the rece iver to the power supply cradle
The RX 6 receiver clips into the charger & power supply cradle. The belt c lip will locate inside the power supply and can only be released using the special release key supplied. Following the installation of the receiver into the charger & power supply cradle check the operation of the receiver. Signals should be received on all channels. Unplug the he ad ph on es an d c he ck th at th e re ce iv er go es in to st an db y mod e a ft er ap pr ox ima te ly 2 minutes, when the sound is muted and the display will turn off. The recei ver will operate and re turn to the state it was in before the headphone lead was removed as soon as the headphones are re connected or the channel select button i s presse d once. The receiver will switch off af ter 40 minutes use to save the battery in case it has

been left on with the headphones plugged in. To restore the receiver press the channel select switch once and it will return to the state it was in before the 40 minute timer operated.
The installation procedure should be repeated for all of the receivers.
Release Keys
Leave a suitable number of release keys for the operator to remove the receivers from the powe r s uppl y if required. Caution; If y ou leave too many release keys the staff will assume that the receive rs are to be remove d and changed round.
User maintenance
The venue staff should be instructed on how to operate the receivers and chargers and how to do simple maintenance. The receivers should be cleaned after use with a damp cloth to remove any sweat and to stop a build up of bacteria. Occasionally the receivers should be removed from their power supplies and both should then be cleaned with a damp cloth and dried with a dry cloth, to prevent the build up of bacteria and ger ms. The receivers should be checked once a week for flat batteries or a malfunction.
The batteries will not require charging in normal operation (unless the installation uses a docking sta tion) and should not need to be moved around the gy m. In the case where some receivers r eceive heavy usage the operator may wish to rotate them to even out the wear and battery usage over a long period of time. If the receiver has a flat battery it will work once the machine is operated (1 to 2 second delay). If it fails to start then the most likely fault is that the power is not being supplied f rom the machine, check that power is available from the CSAFE outlet.
The headphone lead is also the aerial and reception will depend on the lead being in good condition. Deterioration of the headphone lead will cause poor reception and crac kling in the headphones and will requir e changing approximately every three months depending on use. You should demonstrate to the staff how to change the headphone lead and offer t o leave some spare one s. You should also explain that the hea dphone lead is a consumable item and therefore does not have a warranty.
Spare parts
Spare headphone leads, knobs and release key s are available from the manufacturer, we suggest that you leave a price list with the operator.
