* From production week 9703 onwards layout of the printed circuit board has been changed to layout stage 3103 303 3380.1
(The layout stage can be identified by the last digit of the 12-figure number, printed in the copper pattern)
attention: code number 3103 303 3317.7 of copper patter exchanged by new code number 3103 303 3380.1
— the change status begins therefore with .1 again.
reason: - IF- buffer-amplifier added (provisional for Japanese version only)
- SMDs type 1206 changed to smaller SMD type 0805

For the new assembly drawing see attached sheet 7-2-1.
* Adjustment table
Varicap-voltage for 1602kHz was changed to 6,9V+0,5V for FM/MW-versions.
reason: correction
For the new adjustment table see attached sheet 7-2-1 .
