blink rapidly. Turn on the Bluetooth on the device you wish to pair (cell phone, media player, tablet,
computer, etc...) and select "M200 BT4.2". The Blast Box will beep twice and the LED will slowly blink
confirming the connection.
Tips for operation:
• For best results set the
Master Volume
to the 3 o'clock position (pointing to the right) and use your
audio device to control the volume.
• For flattest response position the 4 control knobs (
Sub Level
,
Sub Filter
,
Mid/High Level
, and
Treble
)
to the 12 o'clock position.
• The polar response is angled upwards about 15
°,
so feel free to set the Blast Box on the ground, no need
to worry about listening on axis.
• For best bass response, and highest output, position the Blast Box near a wall or other rigid surface.
• Lower the
Sub Level
and increase the
Mid/High Level
