NOTES: The remote control handset supplied with the C370 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 C370. The Video 2 and Video 3 input
selector buttons (inside section No. 5) on the remote control
handset are inoperative in the case of the C370.
Direct sunlight or very bright ambient lighting may affect the
