Note: Component and circuit are subject to modification to insure best opera-
tion under differing local conditions. This manual is based on Europe (E) stan-
dard, and provides information on regional circuit modification through use of
alternate schematic diagrams, and information on regional component varia-
tions through use of parts list.
1. KENWOOD follows a policy of continuous advancements in development. For this reason specifications may be changed without notice.
2. The full performance may not be exhibited in an extremely cold location (under a water-freezing temperature).
