When The Unit is In Use
* Do not place heavy object on the unit as this may cause it to fall or break which may result in personal injury and/or property damage. In addition, the object it self may fall of and cause injury and/or damage.
Make sure that the volume control is set to mini-
mum position before power is switched on, Loud noise produced at high volume when is power is switched on can impair hearing. * Switch OFF the unit's power before turning the phantom power switch ON or OFF. Operating the switch without switching OFF the main power could resulting a large transient noise thought the speakers, potentially resulting in speaker failure. * Avoid using phantom power when connecting an unbalanced microphone to the MIC 1 input, as the microphone fails. * Do not operate the unit for an extended period of time with the sound distorting. Doing so may cause the connected speakers to heat, resulting in
afire.
* Contact your TOA dealer as to the cleaning. If dust is allowed to accumulate in the unit over a long period of time, a fire or damage to the unit may
result.
ii If dust accumulates on the power supply plug or in the wall AC outlet, a fire may result. Clean it periodically. In addition, insert the plug in the wall outlet securely.
ii Switch off the power, and unplug the power supply plug from the AC outlet for safety purposes when cleaning or leaving the unit unused for 10 days or more. Doing otherwise may cause a fire or electric
shock
