a good idea to turn down your amp or mixer input before you insert or
remove a plug at the endpin jack. Doing so will protect your speakers
(and your ears) from loud pops.
Sleep Mode
When the Onboard Aura is plugged in and you don’t play for 30
seconds, the electronics will go into “sleep” mode to conserve the
battery. As soon as you start to play again, the unit will wake up and
return to its normal operating mode. Note that when the Onboard Aura
is sleeping, it still consumes some power, so we advise you to unplug
the system when you take an extended break.
Power Up
The LEDs in the tuner display flash briefly when you first plug into the
endpin jack, indicating that the power is on. Some ask, “Why is there
no conventional pilot light that stays on when I plug in?” We find that
a steadily lit LED devours too many precious hours of battery life.
Instead, we have the LEDs flash at startup, and this extends the useful
life of the battery. If you need visual confirmation that the power is on,
move the Play/Edit switch to Edit and the (#) LED will flash.
Low Battery Indicator
When the “B” LED in the tuner array flashes once every three
seconds, you have approximately 1.5 hours before the battery is
exhausted. Change it at the next opportunity. When the “B” light
starts flashing every half a second, the battery is practically spent
and should be changed immediately. When the tuner is switched on,
the low battery indicator will function only when no signal is present.
