Very usefully, I could find the trouble clearly with that manual.
;
Bon produit. Permet de corriger les couleurs et de redonnez un petit coup de jeune à vos vieilles vidéos. On regrettera juste le manque d'une prise s-vidéo.
 ;
Quality scan of the actual service manual, just what I was looking for.
;
Straightforward ordering process. Service manual scan was clear & easy to read. Very comprehensive instructions for alignment. Excellent, thank you.
;
Fast, clear and useful. Important for me: the manual is in German.
KAP-2
CIRCUIT DESCRIPTION / COMPONENTS DESCRIPTION / TERMINAL FUNCTION
Circuit Description
â� Public Address (PA) function
The PA output switching relay is controlled by turning the PA function on and off. When the PA is activated, the PA output flows through the following path. The audio signal input from the microphone passes through the filter, amplifier and other circuits of the TX-RX unit (B/3) and goes to pin 5 (SPI) of CN3 of the relay unit. The audio signal passes through the relay (K2) and is output to pin 3 (OSP) of CN2.

â� Horn Alert (HA) function
The relay unit can be controlled by turning the HA function on and off and by using a signaling decode output. The maximum current of HA is 2A. There are two Horn Alert settings: HA1 (Default) and HA2. HA2 can be set by changing the short pin of CN1.
