Important Safety Instructions    (cont’d) 

 

The lightning flash with the arrowhead symbol, within an equilateral triangle, is 

intended to alert the user to the presence of uninsulated “dangerous voltage” within 

the product’s enclosure that may be of sufficient magnitude to constitute a risk of 

electric shock to persons.  

 

The exclamation point within an equilateral triangle is intended to alert the user to the 

presence of important operating and maintenance (servicing) instructions in the 

literature accompanying the appliance. 

 

Marking by the “CE” symbol (shown left) indicates compliance of this device with the 

EMC (Electromagnetic Compatibility) and LVD (Low Voltage Directive) standards of the 
European Community 

 

Please read all instructions and precautions carefully and completely before 

operating your Simaudio MOON 310LP Phono Preamplifier. 

 

1.

 

ALWAYS disconnect your entire system from the AC mains before connecting or disconnecting any cables, 
or when cleaning any component. To completely disconnect this apparatus from the AC mains, disconnect 
the power suppy cord plug from the AC receptacle. 

2.

 

The MOON 310LP must be terminated with a three-conductor AC mains power cord which includes an earth 
ground connection. To prevent shock hazard, all three connections must ALWAYS be used. Connect the 
MOON 310LP 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. The mains plug of the power supply 
cord  shall remain readily accessible. 

4.

 

NEVER use flammable or combustible chemicals for cleaning audio components. 

5.

 

NEVER operate the MOON 310LP 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 310LP with any liquid. If a liquid substance does enter your MOON 
310LP, immediately disconnect it from the AC mains and take it to your MOON dealer for a complete check-
up. 

7.

 

NEVER spill or pour liquids directly onto the MOON 310LP. 

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 310LP. If a problem occurs contact your MOON dealer. 

12.

 

NEVER expose the MOON 310LP to extremely high or low temperatures. 

13.

 

NEVER operate the MOON 310LP in an explosive atmosphere. 

14.

 

ALWAYS keep electrical equipment out of reach of children. 

15.

 

ALWAYS unplug sensitive electronic equipment during lightning storms. 

16.

 

WARNING: Do not expose batteries or battery pack to excessive heat such as sunshine, or fire or the like.
