2. Connect the longer flat cable from the cassette deck to ter-
minals B1 and B2.
After connection:
Keep cables as flat against the back of the unit as possible.
Connect the FM indoor antenna.
Tape the antenna to a wail or column, in a position where radio
signals are received with the least amount of interference.
3} Connect the AM loop antenna.
1. Attach the antenna holder to the rear panel of the CD chang-
er or CD player.
Then ctamp the antenna into the antenna holder.
2, Connect the antenna terminal to the rear panel of the tuner
