Note: All instructions below pertaining to the front panel pushbuttons are given with respect to starting from the "Home Screen."  To get there from any current display on your LCD, press <SELECT> and <ENTER> simultaneously.  <Up>, <Down>, <Right>, and <Left> refer to the buttons labeled with solid black arrows on the front panel.

1. Navigate through the receiver front-panel menus:

The menu layout gives a brief explanation.  In more detail:
• The <Right> and <Left> buttons are used to scroll through the menus to find the desired menu item.
• Once at the desired menu item, the <SELECT> button will either select the next menu level or place you into Edit mode, allowing you to change the values.
• In Edit mode, the <Up> and <Down> buttons allow you to change the selected item to the desired value.
• Where applicable in the Edit mode, the <Right> and <Left> buttons are used to select the next item in the screen for editing.
• Once all items have been set to the correct values, the <ENTER> key will execute the desired changes.
• In Edit mode, the <SELECT> button will cancel out of Edit mode without saving changes.

 
2. List which audio channels labels are currently available on the Unity 4000:

To find out what audio channels are available on the Unity 4000, you need only query the receiver for an MPEG status.
1. Press <Right> 4 times.  Press <SELECT> when you see STATUS REPORTS.
2. Press <Right> 2 times.  Press <SELECT> when you see the MPEG STATUS.
3. Press <Right> 3 times.  AUDIO PRESENCE will show on the top line, with the 3-letter codes for each audio channel listed below.  Use the <Right> and <Left> keys to scroll through the list.

 
3. Tune a certain audio channel to a certain port:
• If you have used a terminal to configure the Preselect Tables (you cannot configure the Preselect Table from the front panel):
1. Press <Right> once.  Press <SELECT> when you see AUDIO SETTINGS.
2. The screen will read PRESET SELECT: PORT 1.  If you desire to modify another port, use the <Right> and <Left> buttons to cycle through to the other port.  Press <SELECT> when you see the port you desire to modify.
3. Use the <Up> and <Down> buttons to select a preset configuration.  Press <ENTER> to excute your choice, or press <SELECT> to cancel.
4. The screen will return to the PRESET SELECT: PORT X display.  If you desire to modify another port, use the <Right> and <Left> buttons to cycle through to the other port.  Press <SELECT> when you see the port you desire to modify, and repeat the above step.



---

NOTE: You cannot select a service to more than one port simultaneously.  Attempting to do so will display the following:
XYZ: Program used on PortX: Move to PortY.
If you press <ENTER> at this point, it will REMOVE the selected service from the previous port, and move it to the currently selected port.
Press <Up> or <Down> to choose "Cancel" and hit <ENTER> to cancel the operation.

---

• If you have not configured the Preselect Tables:
1. Press <Right> once.  Press <SELECT> when you see AUDIO SETTINGS.
2. Press <Right> 4 times.  Press <SELECT> when you see DETAILED SETTINGS.
3. The screen will come up on Port 1.  Press <Right> the appropriate number of times if you desire to change another port.  Press <SELECT> to enter Edit mode for this channel.
4. The SRVC ("Service") begins flashing.  Use <Up> and <Down> to select the desired audio channel.
5. Press <Right> or <Left> to select another field to modify in this screen, if desired.  You can adjust the Attenuation (between 0 and 14 dB of attenuation -- no amplification is possible), as well as the Route (S=Stereo, R=Reverse, 1=Left Encoder input on both receiver outputs, 2=Right Encoder input on both receiver outputs).

NOTE: If the selected audio channel is a mono channel, the Route has no effect.  You may still select it, but it will not affect the audio routing.  (An audio channel encoded in mono cannot be played as anything but mono.)
6. Press <ENTER> to execute your changes, or press <SELECT> to cancel.


4. Properly route a dual-mono channel:

An audio channel may be encoded at the originating source as either a Mono signal or as a Dual Mono signal.  If the signal is encoded as Dual Mono, it may actually be a stereo pair, or it may have discreet (independent) audio on left and right inputs.  If you desire to utilize a dual-mono audio channel that contains discreet audio, you will have to select the appropriate Route setting when you select the audio channel.  As noted above, the following four choices are available:
 

S	Stereo Encoder Left input to Receiver Left output Encoder Right input to Receiver Right output
1	1 on Both Encoder Left input to Receiver Left output Encoder Left input to Receiver Right output
2	2 on Both Encoder Right input to Receiver Left output Encoder Right input to Receiver Right output
R	Reverse Stereo Encoder Left input to Receiver Right output Encoder Right input to Receiver Left output


You may set just the audio routing by following the above steps, and change just the routing without adjusting the Service.  This only works when you are not using Preselect configurations, as the Preselects store the audio routing.


5. Properly route a mono channel:
   If the signal is encoded as a mono source, the receiver will output the same signal on both Left and Right outputs, regardless of the Route setting.



6. Set the receiver label:
   You can change the default label on the front LCD screen to any 20-character label. To do so:
   1. Press <Right> 3 times.  Press <SELECT> when you see HARDWARE SETUP.
   2. Press <Right> 6 times.  Press <SELECT> when you see the UNIT LABEL.
   3. Use <Left> and <Right> to select the letter.  The <Up> and <Down> buttons may be used to change the individual letter to your desired label.
   4. Press <ENTER> to save changes, or <SELECT> to cancel.
   
    
7. Set up the receiver serial ports:
   
   1. Press <Right> 3 times.  Press <SELECT> when you see HARDWARE SETUP.
   2. Press <Right> 4 times.  Press <SELECT> when you see SERIAL PORTS.
   3. Press <SELECT> to edit the two serial ports' configuration. You may have either port as any of: Printer, Terminal, Modem, or Aux Data. The only limitation is that you may not have both Modem and Terminal selected at the same time.  Use <Right> or <Left> to modify the other serial port, and <Up> and <Down> to modify the selection.
   4. Press <ENTER> to save changes, or <SELECT> to cancel.
   
    
8. Set up the printer or terminal baud rate on the serial ports:
   
   1. Press <Right> 3 times.  Press <SELECT> when you see HARDWARE SETUP.
   2. Press <Right> 4 times.  Press <SELECT> when you see the SERIAL PORTS.
   3. Press <Right> 2 times for the Printer settings, or 3 times for the Modem settings.
      Press <SELECT> when you see PRINTER SETTINGS or MODEM SETTINGS, as appropriate.
      NOTE: The Terminal settings are slaved to follow the Modem settings.  Set the Modem speed to change the Terminal speed.
      
   4. Use <Up> and <Down> to modify the baud rate serial port, and <Up> and <Down> to modify the selection. (The Printer Port also allows modification of the Parity setting.)
   5. Press <ENTER> to save changes, or <SELECT> to cancel.
   
    
9. Read email when the front panel says "WARNING: Email Present":
   
   1. Press <Right> 2 times.  Press <SELECT> when you see EMAIL  READ:<SELECT>
   2. Press <Right> as many times as needed to scroll through the message. <Left> may be used to scroll backwards if needed.
   3. Press <Enter> when you see --END OF EMAIL--
   4. Press <SELECT> when RETURN displays.
   5. At this point you have the option of reading the email again or Clearing it.
      Press <SELECT> to read it again, or <ENTER> to clear it from memory.
      To return to the previous menu without either reading or clearing the email, press <Left> twice.
   6. NOTE: Email will be overwritten each time a new message arrives.  Therefore, it is important to read email as soon as possible after it arrives.
