How to Perform a Master Reset (M R)

It is sometimes necessary to do a Master Reset (M R) on your 4DTV. This definitely needs to be done if the receiver’s TDT count has reached 1920 as this means the memory is full and will no longer accept new information such as new satellites. Usually this procedure is done by licensed professional C-Band technicians, but quite often there are none available at a customer’s location and it becomes necessary for a 4DTV owner to perform this operation. This procedure will erase all the all satellite positions, skew settings, limits and LNB settings from the receiver’s memory. Reprogramming the receiver will take anywhere from one to two hours.

Please read the following complete instructions for performing a Master Reset (M R) before beginning. NPS is not responsible for any damage due to the use of these instructions. If you do not feel you are capable of performing the M R safely, call a local C-Band satellite technician (NPS may be able to help locate a technician near you) or Motorola (if under warranty) at 1-800-976-5174 for technical help.

1. Record a list of all your satellites and their dish positions. The Dish Position can be found by going to each satellite and pressing Options 5 (press Exit or Go Back to exit). This function will display the Dish Position of that particular satellite. Write down only those that you currently have programmed in correctly. Also write down the East and West limits that are currently programmed into your 4DTV. The new dish positions (after M R) will most likely not be the same as they were before the M R, because the 4DTV will automatically assign dish position 5000 to whatever position the satellite is sitting on when the M R is performed. However, the difference between the satellites will remain the same. Ex: Prior to M R: G5 is at 5010 and G9 is at 5030. After M R G5 might be at 4940 and G9 would then be at 4960. Please note in both cases the position of the satellite is 20 counts apart. (We recommend that you do not program in A1 & A2 as these satellites can cause the TDT count to reach 1920 again).

2. After recording all satellites and their Dish Position, move your dish to the G1 satellite whenever possible and then tune in to a digital channel such as G1-03 or G1-13. Tune these channels to the highest Quality value possible and make sure the DC green light is on before starting the M R. If it is not possible to program in the G1 satellite due to trees, hills, etc., a M R can be performed on any other satellite or at current dish position 5000, if necessary.

3. You are now ready to erase all the satellite locations from your receiver’s memory by pressing Options, 6, 7, 7, 8, 7 and Enter on your remote control. This is a hidden menu and the screen on your TV will not change when you press these numbers on your keypad. The receiver should turn itself off and then immediately turn back on again. It will display 888*** and then WM UP on the front of the 4DTV. After several minutes, it will display a time on the display, but probably not the correct time of day.

4. Press the POWER button on your remote control and the display should show a channel number on the front of your receiver, but no satellite number will appear since they have all been erased by the master reset.

5. Push Options 6, 4, 2 on your remote control, set the Linear East or Linear West and LNB Type the same as it was prior to doing the master reset.

6. Press GO BACK, then press 3, 3 and a list of factory default satellites should appear on your TV screen. Scroll by using the arrow keys around the Enter button to G1, (or to whichever satellite you were set on when you started this procedure). Press Enter on your remote control and theTV screen should display the tuning screen for you to tune in the G1 satellite. Use the channel up/down key to change the channel at the top of the screen to G1-11. Then use the arrow key below the Enter button to move down to the auto-peak skew line and press Enter. This only needs to be done if you have a C-Band LNB – it is not necessary if you have a C-Band LNBF. If you have a C-Band LNBF there will be no option on your screen to adjust skew. A picture of EWTN religious channel should appear in the background behind the tuning screen. Change the channel to G1-12 using the channel up/down button, push Enter on the auto-peak skew screen again and a picture of SHOP NBC should appear in the background. It is very important that the picture on G1-11 be tuned using the dish position and skew settings to obtain as perfect picture quality as possible without sparklies, blurring, etc. Then change the channel to G1-13 and look at the number for Signal and Quality at the bottom of the screen. It is important that the Quality number be as high as possible. Model 922 receivers must have a Quality of at least 40 to obtain a “digital lock” (Some older General Instrument 920 receivers must have a Quality reading of at least 20 instead of 40). A green DC light should appear on the front of your 4DTV below the channel 13 number, above the letters DC. You can also use other channels on G1 to try to get a green DC light, like G1-03, and G1-18. After you have a green DC light on a G1 channel, push GO BACK and then ENTER on your remote control to save the settings in memory for G1, then press EXIT once , VIEW once, or GO BACK four times to get out of the tuning screen.

7. Press Option 6, 5 on your remote control and you should have a screen with your unit id at the top and trip counter on the bottom left, and channels counter on the bottom right. Channel count will be approximately 575 at this point. Leave the 4DTV sit on G1-13, G1-03, or G1-18 approximately 30 minutes while the receiver maps into memory all the satellite names, channel names, frequencies, etc. You must have a green DC light on the front of your receiver for this process to work. If you do not have a green DC light, continue to fine tune until one appears (on G1). The channel counter should keep increasing slowly up to approximately 4804 and then stop. Wait 10 more minutes to make sure it is finished counting. Call your program provider (NPS) and ask for a digital rehit. This can also be done by using our online service at www.callnps.com. The number on the trip counter should increase from 0 to 5 when your receiver has been authorized. It is possible to download the IPG (Guide) at this time – simply press the Guide button, then the Info button on your remote control and wait about 15 minutes. If you do not wait – the guide will not download properly.

8. Press GO BACK on your remote control to return to the Options screen, then press Option 6, 4, 3 ,3, and you will see that the number of available satellites has increased. Select C4 and press Enter to show the C4 tuning screen. Use the channel up/down key to scroll up to channel 9, which is QVC Shopping Channel (at the time of this writing). Move to the dish position line and use the right arrow key on your remote control to move your satellite dish to the West until you get a good picture on C4-09. CAUTION: Make certain your dish is moving to the West as the dish position numbers increase – no more than 40 counts higher than G1. It is possible to move your dish off the end of the actuator arm causing damage if you move the dish too far. If possible, have someone assist you by actually watching the dish while it is moving. Refer back to your original notes and check to see how far apart C4 is from G1 in order to properly gauge correct distance. It is very important that you tune dish position until you get as good a picture as possible on this channel because your 4DTV will use the dish position for the first two satellites that you program into your 4DTV to calculate where it projects all the other satellites will be located. Press GO BACK and ENTER to store the dish position and skew settings in memory for C4.

9. Press GO BACK and you should be on the SET LIMITS screen. Highlight the West limit and use your right arrow button on your remote control to set the West limit approx. 10 counts higher than where you programmed C4.

10. Press 3 (Program Satellites) and the list of all satellites should reappear on your TV screen. Select C3, push ENTER and scroll to channel C3-7, C SPAN (at the time of this writing). The top line will say “move dish to ####”. This is the location that your 4DTV thinks the C3 satellite will be located - based upon the dish position you stored for G1 and C4. That line (Dish Position) should be high-lighted in yellow on your TV screen. Push ENTER on your remote control and the dish will automatically move to that location. A picture of C SPAN should appear on your TV screen behind the tuning screen. If a picture does not appear, scroll to the auto-peak dish position line and press Enter and then after the dish finishes moving (when the Dish Position numbers stop changing), scroll to the auto-peak skew line and hit Enter and a picture should appear. Press GO BACK and then ENTER to save C3 settings. The H (horizontal) and V (vertical) readings (if you have an LNB and not an LNBF) should be approximately 90 degrees apart. Example: H (45) V (-45).

11. Continue using the above procedures to find, tune, and store in memory all the satellites you desire. After you find the Eastern most satellite in your list of satellites, press Option 6, 4, 3 to display the SET LIMITS screen again and move the East Limit approx. 10 positions lower than your Eastern most satellite (usually the W3 satellite). Once again, please use extreme caution not to move your dish off the actuator arm.

12. Now press EXIT and you are finished with the Master Reset!
