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 addi-

tion, 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
