Please read all instructions and precautions carefully and completely before

operating your Simaudio MOON W5.3 Stereo Power Amplifier.

1.ALWAYS disconnect your entire system from the AC mains before connecting or disconnecting any cables, or when cleaning any component.

2.The MOON W5.3 must be terminated with a three-conductor AC mains power cord which includes a protective earthing connection. To prevent shock hazard, all three connections must ALWAYS be used. Connect the MOON W5.3 only to an AC source of the proper voltage; Both the shipping box and rear panel serial number label will indicate the correct voltage. Use of any other voltage will likely damage the unit and void the warranty

3.AC extension cords are NOT recommended for use with this product.

4.NEVER use flammable or combustible chemicals for cleaning audio components.

5.NEVER operate the MOON W5.3 with any covers removed. There are no user-serviceable parts inside. An open unit, especially if it is still connected to an AC source, presents a potentially lethal shock hazard. Refer all questions to authorized service personnel only.

6.NEVER wet the inside of the MOON W5.3 with any liquid. If a liquid substance does enter your MOON W5.3, immediately disconnect it from the AC mains and take it to your MOON dealer for a complete check- up.

7.NEVER expose the MOON W5.3 to dripping or splashing of liquids and no objects filled with liquids, such as vases, shall be placed on top.

8.NEVER block air flow through ventilation slots or heatsinks.

9.NEVER bypass any fuse.

10.NEVER replace any fuse with a value or type other than those specified

11.NEVER attempt to repair the MOON W5.3. If a problem occurs contact your MOON dealer.

12.NEVER expose the MOON W5.3 to extremely high or low temperatures.

13.NEVER operate the MOON W5.3 in an explosive atmosphere.

14.ALWAYS keep electrical equipment out of reach of children.

15.ALWAYS unplug sensitive electronic equipment during lightning storms.
