To view the list of locked out channels:
1. Press the PL SET key two times. An asterisk (*) indicates each locked out channel.
2. Press VIEW to exit this list.
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. 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. 3, Realign Satellite Memory. The name of the satellite and the channel is
displayed. Verify these are what you chose in steps 1 and 2.
5. Use the EAST and WEST keys to obtain a good, clear picture that matches the satellite and
channel you chose.
6. If this is the correct satellite and channel, press ENTER. The entire satellite memory has
been realigned to your dish.
7. 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.
3. Check the Receiver’s Input Mode. Locate the Receiver Input Mode Switch on the receiver
back panel. Refer to page 9 of your Owner’s Manual. Move the switch to the “C & Ku”
position.
4. Go through the channels. If this solved the problem, you are done.
5. If this did NOT solve the problem, put the Input Mode switch back to its original position
and continue to step 6.
6. Perform the Skew Adjustment. Refer to page 34 of your Owner’s Manual.
a. Put the receiver in Program Mode. Locate the Receiver Mode Switch on the receiver
back panel. Refer to page 9 of your Owner’s Manual. Move the switch to the
“PROGRAM” position.
b. Press FUNCTION.
c. Select No. 2, Adjust Skew. Write down the current Skew Angle number. You may need
to reset this.
d. Use the EAST and WEST keys to run the Skew Angle all the way down to zero and all
the way up to 65.
e. If the picture does NOT come in clear somewhere in this range, set the skew number
back to what is was in step 6.c. Press ENTER and put the receiver back in Auto Mode.
Locate the Receiver Mode Switch on the receiver back panel. Refer to page 9 of your
Owner’s Manual. Move the switch to the “AUTO” position. Then proceed to step 7.
f. If the picture DOES come in clear somewhere in this range, adjust the skew for the best
picture. Press ENTER.
g. View the other channels on this satellite.
h. If all the channels are now OK, put the receiver back in Auto Mode. Locate the Receiver
Mode Switch on the receiver back panel. Refer to page 9 of your Owner’s Manual.
Move the switch to the “AUTO” position. You are done.
i. If all the channels are NOT OK, repeat the above steps to adjust the skew to what it was
in step 6.c. Proceed to step 7.
7. Check the polarization wires. Refer to page 9 of your Owner’s Manual. At the bottom of the
page is a picture of the back panel of your receiver. Locate terminals number 10, 11, and 12.
Check the connections in these terminals.
8. The wires are usually colored red in 10, white in 11, and black in 12. Reconnect any loose
wires. Check all the channels again. If this solved the problem, you are done. If not,
proceed to step 9.
9. The problem is likely the polar rotor, at the out door unit. Contact your satellite
dealer/installer for assistance.
Initial Set Up
Initial Set Up was performed during the original system installation and should not have to be
