Entertainment Systems
Keep the CD changer door closed. Coins and foreign objects will damage
the CD player and void your audio system warranty.

RADIO FREQUENCIES

AM and FM frequencies are established by the Federal Communications
Commission (FCC) and the Canadian Radio and Telecommunications
Commission (CRTC). Those frequencies are:
AM - 530, 540–1700, 1710 kHz
FM- 87.7, 87.9–107.7, 107.9 MHz

RADIO RECEPTION FACTORS

There are three factors that can effect radio reception:
• Distance/strength: The further you travel from an FM station, the
weaker the signal and the weaker the reception.
• Terrain: Hills, mountains, tall buildings, power lines, electric fences,
traffic lights and thunderstorms can interfere with your reception.
• Station overload: When you pass a broadcast tower, a stronger signal
may overtake a weaker one and play while the weak station frequency
is displayed.

CASSETTE/PLAYER CARE

Do:
• Use only cassettes that are 90 minutes long or less.
• Tighten very loose tapes by inserting a finger or pencil into the hole
and turning the hub.
• Remove loose labels before inserting tapes.
• Allow tapes which have been subjected to extreme heat, humidity or
cold to reach a moderate temperature before playing.
• Clean the cassette player head with a cassette cleaning cartridge after
10–12 hours of play to maintain good sound/operation.
Don't:
• Expose tapes to direct sunlight, extreme humidity, heat or cold.
• Leave tapes in the cassette player for a long time when not being
played.
