Fig. 2-2-26

Locating procedure

1. Enter the mechanism assembly into the PLAY mode.

(Refer to page 2-2.)

2. When the “

” part is positioned down, make sure that

the part “a” of the tension arm assembly is located within
the range of “b”.

3. If the part “a” is out of the range, turn the pin “c” to

adjust the position.
