NOTES: The remote control handset supplied with the C730 is of
a universal NAD type, designed to operate several NAD models.
Some buttons on this handset are inoperative, as the functions
aren't supported by the C730. The Video 2, Video 3 input selector
buttons (inside section 5), tuner Bank button (section 7),
speakers A and Speakers B buttons (section 3) on the remote
control handset are inoperative in the case of the C730.
Direct sunlight or very bright ambient lighting may affect the
operating range and angle for the remote control handset.
The infrared remote control command receiver, located on the far
left of the display window, receives commands from the remote
control. There must be a clear line-of-sight path from the remote
control to this window; if that path is obstructed, the remote
control may not work.
