Turning The Power On/Off; Important < Caution When Turning Off The Power - Boss RC-20 Owner's Manual

Turning the power on/off

Once the connections have been completed, turn on power to your various devices
in the order specified. By turning on devices in the wrong order, you risk causing
malfunction and/or damage to speakers and other devices.
When turning the power on: Turn on the power of the amp or mixer last.
When turning the power off: Turn off the power of the amp or mixer first.
NOTE
* Always make sure to have the volume level turned down before switching on power. Even
with the volume all the way down, you may still hear some sound when the power is
switched on, but this is normal, and does not indicate a malfunction.
* If you are using batteries, the indicator will become darker when the batteries run down.
Please replace the batteries as soon as possible.
Important < Caution when turning off the power >
Before you turn off the power, make sure that the following conditions are
met. All saved data may be lost if the power is turned off inappropriately.
• You must not be playing/recording/overdubbing a phrase
(The REC, PLAY, and OVERDUB indicator must not be lit)
• The WRITE indicator or EXIT indicator must not be lit
• The PHRASE USED indicator is not blinking
To avoid problems, select an empty phrase track whenever possible, and turn
off the power.
If you are using batteries, the power will be turned off automatically when the
connector plug to your amp or speaker is unplugged from the OUTPUT jack.
Before unplugging this connector, make sure you check for the above states.
When turning on the power while a recorded track is being selected
(the PHRASE USED indicator is lit), the indicators on the front panel
flash in a sequential order, and the PHRASE USED indicator blinks
for a few seconds.
If you turn off the power while the PHRASE USED indicator is
blinking, the saved phrases will be erased.
Do not turn off the power while the PHRASE USED indicator is
blinking.
To avoid problems, select an empty phrase track whenever possible,
and turn on the power.
