3. If you have a VHF
antenna, disconnect it from your TV set..
4. Connect your VHF antenna cable to the screw terminals labeled "an-
tenna input" on the switchbox. If your antenna
cable is the round
75-ohm coax type, use a 75-ohm to 300-ohm adapter (not supplied)
to attach your antenna cable to the switchbox.
5. Connect the twin lead output cable of the antenna switchbox to the
VHF antenna terminals of your TV set. If your set is one of the newer
types with a round 75-ohm VHF connector, 'you will need a 300-ohm
to 75-ohm converter (not supplied) to connect the switchbox to the
75-ohm VHF antenna input on the set.
6. Set the TV's VHF tuner to the channel number indicated on the com-
puter's channel selector switch (channel
3 move
the switch to the left,
channel 4
move
the switch to the right). If a strong local TVsignal is
present on one of these channels, select the other channel to avoid
possible interference.
8. Plug
the
power supply cable into the power socket on the side of the
Commodore 64. Just push it in. It is "keyed" to allow insertion in only
one direction, so you can't connect the power cord the wrong way.
The power supply converts household current into the form the com-
puter uses.
