Fine Tune a Satellite

If you must use your East or West keys to obtain a clear picture on a certain satellite, every time
you view that satellite, it is necessary to fine tune that satellite. Perform the following steps.

1. Move to the satellite in question.

2. Use the EAST and WEST keys to obtain the best possible picture.

3. Follow the steps in the Add a New Satellite procedure, as if you are entering this satellite as
a new satellite.

If you must frequently fine tune a particular satellite, there may be problems with your out door
unit. Contact your local satellite dealer/installer for assistance.

Delete a Satellite

As older satellites go out of service and new satellites are launched, you may need to delete old
satellite names to make room for new ones. Perform the following steps.

5. Use the EAST or WEST keys to scroll the arrow through the list of satellites. Move the
arrow to the satellite name you wish to delete. Be sure this is the satellite name you wish to
delete.

6. Press CANCEL. This satellite name and location are erased from the memory.

7. Put the receiver back in Auto Mode.
a. Press FUNCTION.
b. Select No 4, Receiver Mode.
c. Select No. 1, Auto. Verify the arrow is pointing to “Auto.”
d. Press ENTER. The receiver is now in Auto Mode. If you have no picture, move to

the receiver back in Auto mode and repeat the above process, selecting “Enable” at step 6.

Satellite Memory Realignment

If all satellites are misaligned in the same direction and by the same amount, the dish has most
likely been shifted by high winds or other force. This function allows you to realign your dish to
match the already stored satellite positions without having to reprogram or fine tune all of the
satellites individually.
Use this function ONLY if all of your satellites are misaligned in the same direction (east or
west) and by the same amount.

1. Call up or move to a satellite you are familiar with.

2

2. Choose a known active channel on that satellite. Use a channel easy for you to identify,
though the picture may be poor or missing.

3. Press FUNCTION.

4. Select No. 2, Change Program.

5. Select No. 7, Realign Sat. Memory. The name of the satellite and the channel is displayed.
Verify these are what you chose in steps 1 and 2.

6. Use the EAST and WEST keys to obtain a good, clear picture that matches the satellite and
channel you chose.

7. If this is the correct satellite and channel, press ENTER. The entire satellite memory has
been realigned to your dish.

8. Call up other satellites and verify they are aligned correctly. Repeat the above steps, if
necessary.

If you must frequently realign the satellite memory, there may be problems with your out door
unit. Contact your local satellite dealer/installer for assistance.

Missing Odd or Even Channels

If you are missing the odd or even known active channels on any or all satellites, perform the
following steps.

1. Move to the satellite with missing channels. Select the missing channel.
a. If the picture is black, the problem may be a missing subscription channel. Refer to the

“Missing Subscription Channel” flowchart near the end of this booklet.

b. If the picture is scrambled or very snowy, continue with step 2.

2. Turn off the Parental Control.

the way up to 80.

f. If the picture does NOT come in clear somewhere in this range, set the skew number

back to what is was in step 4.d. Press VIEW and proceed to step 5.

g. If the picture does come in clear somewhere in this range, adjust the skew for the best

picture.

h. Select No. 3, CH. Use the EAST or WEST keys to view the other channels on this

1500.) At the bottom of the page is a picture of the back panel of your receiver. Locate
terminals number 20, 21, and 22. Check the connections in these terminals. The wires are
usually colored black in 20, white in 21, and red in 22. Reconnect any loose wires. Check
all the channels again. If this solved the problem, you are done. If not, proceed to step 6.

6. The problem is likely the polar rotor, at the out door unit. Contact your satellite
dealer/installer for assistance.
