C000 : CASSETTE SW
This submenu checks the functions of six cassette tab sensors and three REC inhibit
sensors (switches).
Checking
Be sure to check each sensor (switch).
(1) Push a sensor (switch) with a finger, and hold it.
. Check the superimposed display to see that a character below the correspond-
ing SW number changes from “0” to “1”.
(2) Release the sensor (switch).
. Check the superimposed display to see that above-mentioned “1” returns to “0”.
(3) To finish the check, press the MENU button once.
In case of NG
When any cassette tab sensor (1 to 6) is NG:
. Check the corresponding sensor on the PTC-59 board.
. Check the corresponding sensor input port of MPU (IC1 on the MS-58 board).
When any REC inhibit sensor (7 to 9) is NG:
. Check the corresponding sensor on the MS-58 board.
. Check the corresponding sensor input port of MPU (IC1 on the MS-58 board).
