7. When you have
inserted the proper
VHF or UHF channel
tabs, use the Perma-
Set fine-tuning
control, dial scale
and dial scale pointer to fine-tune the channels. These
controls are located to the right of the channel tab.
Select the channel you want to fine-tune by pushing
the proper channel selector button (located at the left
of the channel number). The channel number will
then be illuminated.
. Using the dial scale pointer as a guide, turn the
Perma-Set Fine-tuning control (located at the right
side of the dial scale) to locate the channel you want.
The upper numbers on the dial scale are for VHF
channels, the lower ones for UHF channels.
To fine-tune this channel, turn the Perma-Set Fine-
tuning control first in one direction, then in the other,
until you get a sharp, clear picture. If you turn the knob
too far to the left, the color picture goes to black-and-

white. If you turn it too far to the right, the color picture
breaks up into wavy lines. You'll find the sharpest,
clearest picture at a point just before the picture
starts to break up.
. Repeat steps 4, 5, 6, 7 and 8 for each VHF and UHF
channel you wish to receive.
Replace the dial scale cover panel.
Close the control panel door. Now that you have the
channels set up, all you have to do to choose the
channel you wish to view is to touch me button at the
left of the channel indicator.
REMEMBER: Whenever you wish to change the
channel settings, always repeat steps 4, 5, 6, 7 and 8.
When you are satisfied with the VHF-UHF fine-tuning
on all channels, turn the AFC switch ON and leave it
ON. This "locks" in the tuning to each channel, so that |
every time you change channels, you'll get a clear,
sharp picture.
NOTE: In some cases where TV signals are not normal,
you may get a better picture with the AFC switch OFF.
If you get a better picture with the AFC switch OFF,
leave it OFF.
