OPERATION

1.Make sure the amplifier or receiver power is OFF and set the volume to minimum.

2.Set the volume on the volume control to maximum (fully clockwise).

3.If you are using a Niles speaker-selection system, locate the ON/OFF button that corresponds to the speaker pair you wish to play. Set it to the ON position. Make sure the defeat- able protection circuit is not enabled. See Using Speaker Selectors with IM Volume Controls, on page 4.

4.Turn ON the amplifier or receiver and select a source, such as the tuner or CD player.

	to the desired listening level. If all the speaker pairs in your

	button again.

PROGRAMMING CAPABILITY

You can program individual WMVC 100 and WMVC 100E Muting Volume Controls attached to an MVC HUB4, allowing certain locations (such as the guest bedroom and porch) to remain muted when system activation turns on other locations (such as the kitchen and family room).

To program a WMVC 100 or WMVC 100E for automatic muting or unmuting, press and hold the mute button for 10 seconds. An LED blinks to indicate that programming has occurred.

The WMVC 100 and WMVC 100E come from the factory pre- programmed in the automatic mute mode.
