one another. Outside electrical or atmo-
spheric interference can also cause inter-
ference that results in strange sounds.
Whenever you hear unusual sounds and
believe that you are encountering interfer-
ence, press and release the MENU touch-
pad until FREQ appears on the screen, as
shown in the illustration above. The Upper

(+) and (-) touchpads to change this fre-
quency until you find one with little or no
interference.
Volume
After pressing the MENU touchpad to
display VOLUME on the screen, the fac-
tory setting for the loudness of the target
