“OFF” position. Place it in the “ON” position.

b. The speaker may be faulty. Return it for service.

c. The control board may be faulty. Return it for service.

Possible Solutions:

boards are located on the selector switch on the appropriate control board.

These can be set to allow or disallow the sports tunes. To enable the sports

tunes, set the appropriate last switch (#5 or #7) to the “closed” position.

Note: First remove or disconnect power, change the switch setting

and then reapply power. See Fig. 31 or 32, page 5-3 and the draw-

ing on page 5-4.

b. If Selector Switch #5 or #7 is set correctly and the sports tunes do not

operate, the control board may be bad. Return the control board for

service.
