USING THE UNIT SAFELY

WARNING
Concerning the Auto Off function
The power to this unit will be turned off automatically after a predetermined amount of time has passed since it was last used for playing music, or its buttons or controls were operated (Auto Off function). If you do not want the power to be turned off automatically, disengage the Auto Off function (p. 5).

Secure a sufficient amount of space at the setup location
Since this unit normally emits a slight amount of heat, make sure to secure sufficient space around it, as shown below.

Use only the supplied AC adaptor and the correct voltage
Be sure to use only the AC adaptor supplied with the unit. Also, make sure the line voltage at the installation matches the input voltage specified on the AC adaptor’s body. Other AC adaptors may use a different polarity, or be designed for a different voltage, so their use could result in damage, malfunction, or electric shock.

Use only the supplied power cord
Use only the attached power cord. Also, the supplied power cord must not be used with any other device.

Handle lithium batteries carefully

• Lithium batteries must never be recharged, heated, taken apart, or thrown into a fire or water.

• Keep lithium batteries out of reach of small children.
  If a child has accidentally swallowed a battery, see a doctor immediately.

• Never expose lithium batteries to excessive heat such as sunshine, fire or the like.

CAUTION

Handle the ground terminal carefully
If you remove the screw from the ground terminal, be sure to replace it; don’t leave it lying around where it could accidentally be swallowed by small children.
When refastening the screw, make that it is firmly fastened, so it won’t come loose.

Precautions concerning use of phantom power supply
Always turn the phantom power off when connecting any device other than condenser microphones that require phantom power. You risk causing damage if you mistakenly supply phantom power to dynamic microphones, audio playback devices, or other devices that don’t require such power. Be sure to check the specifications of any microphone you intend to use by referring to the manual that came with it.
(This instrument’s phantom power: 48 V DC, 10 mA Max)]
