CM30B, CM60B User Manual
USB player
When a USB memory stick is inserted into the USB port, the USB symbol will show in the bottom left
part of the display and any compressed audio files will start to play automatically. If playback does
not start automatically, press the MEDIA SELECT button (1) and Play/Pause button (3) to check if the
player is set to the correct mode. Try Previous track and Next track buttons (2, 4) if the selected
track is unable to play. Otherwise, check that the audio files are standard compressed type.
Turn up the MEDIA volume control gradually to hear the output from the speakers and increase to
the required level.
Normal playback will read through all tracks on the storage device. Pressing the REPEAT button (5)
will step through the repeat modes ONE (repeat current track), rAND (random), ALL (repeat all)
Pressing the Previous track button (6) briefly steps backwards through tracks on the memory device.
Press and hold this button to decrease the playback volume.
Pressing the Next track button (8) briefly steps forwards through tracks on the memory device.
Press and hold this button to increase the playback volume.
To pause the current track, press the Play/Pause button (7) and press it again to resume playback.
The display will show the track number when a track is selected and then the elapsed time when it is
playing.
AUX input
When a playback device is connected to the 3.5mm AUX input, the display will show AUX.
Alternatively, this source can be selected by the MEDIA SELECT button.
For AUX input, the Play/Pause button acts as a mute control.
The output level of this AUX input is controlled by the MEDIA volume control and is independent of
the rear RCA line inputs. When other media player sources are selected, this AUX input is muted.
Fog/Siren/Alert buttons
In addition to audio controls, the CM60 front panel has 3 warning sound buttons. Pressing any of
these will issue one of 3 preset warning sounds through the speakers for alerts and/or emergency
announcements.
To avoid loud pops through the speakers, turn down the MASTER control before powering down.
