Page 20: Antenna Connections
ANTENNA CONNECTIONS Each antenna should be connected to the designated terminals correctly, referring to the following diagram. Both AM and FM indoor antennas are included with this unit. In general, these antennas will probably provide sufficient signal strength. Nevertheless, a properly installed outdoor antenna will give clearer reception than an indoor one. If you experience poor reception quality, an outdoor antenna may result in improvement. -

Page 45: Remote Control Transmitter
The remote control transmitter provided with this unit is designed to control all the most commonly used functions of this unit. If the CD player, tape deck, LD player, DVD player, etc. connected to this unit are YAMAHA components designed for remote control compatibility, then this remote control transmitter will also control various functions of each component. - Page 46 (This switch will not function when the lid is closed.) Normally, set this switch to the “A” position. When controlling a Yamaha LD player or DVD player by using the CD/LD/DVD player keys ( ), set this switch to the “C” position.
- Page 47 If the memory capacity of the remote control transmitter becomes full, no further learning is possible even if some learning-capable keys are not occupied with new functions. If, for example, you store Yamaha codes only into this remote control transmitter, up to about 20 functions can be stored.
