RISK OF ELECTRIC SHOCK

DO NOT OPEN

CAUTION

To reduce the risk of electrical shock, do not open the unit. No user 
serviceable parts inside. Refer servicing to qualified service personnel.

The symbols shown below are internationally accepted symbols 
that warn of potential hazards with electrical products.

This symbol indicates that a dangerous voltage 
constituting a risk of electric shock is present 
within this unit.

This symbol indicates that there are important 
operating and maintenance instructions in the 
literature accompanying this unit.

WARNING

IMPORTANT SAFETY INSTRUCTIONS

1. Read these instructions.
2. Keep these instructions.
3. Heed all warnings.
4. Follow all instructions.
5. Do not use this apparatus near water.
6. Clean only with a dry cloth.
7. Do not block any ventilation openings. Install in accordance with manufacturer’s instructions. 
8. Do not install near any heat sources such as radiators, registers, stoves, or other apparatus (including amplifiers) that produce heat.
9. Do not defeat the safety purpose of the polarized or grounding-type plug. A polarized plug has two blades with one wider than the other. A 

grounding-type plug has two blades and a third grounding prong. The wide blade or third prong is provided for your safety. If the provided plug 
does not fit into your outlet, consult an electrician for replacement of the obsolete outlet.

10. Protect the power cord and plug from being walked on or pinched particularly at plugs, convenience receptacles, and the point where it exits from 

the apparatus. 

11. Only use attachments and accessories specified by Rane.
12. Use only with the cart, stand, tripod, bracket, or table specified by the manufacturer, or sold with the apparatus. When a cart is used, use caution 

when moving the cart/apparatus combination to avoid injury from tip-over. 

13. Unplug this apparatus during lightning storms or when unused for long periods of time.
14. Refer all servicing to qualified service personnel. Servicing is required when the apparatus has been damaged in any way, such as power supply 

cord or plug is damaged, liquid has been spilled or objects have fallen into the apparatus, the apparatus has been exposed to rain or moisture, does 
not operate normally, or has been dropped.

15. The plug on the power cord is the AC mains disconnect device and must remain readily operable. To completely disconnect this apparatus from 

the AC mains, disconnect the power supply cord plug from the AC receptacle.

16. This apparatus shall be connected to a mains socket outlet with a protective earthing connection.
17. When permanently connected, an all-pole mains switch with a contact separation of at least 3 mm in each pole shall be incorporated in the 

electrical installation of the building. 

18. If rackmounting, provide adequate ventilation. Equipment may be located above or below this apparatus, but some equipment (like large power 

amplifiers) may cause an unacceptable amount of hum or may generate too much heat and degrade the performance of this apparatus.

19. This apparatus may be installed in an industry standard equipment rack. Use screws through all mounting holes to provide the best support.

WARNING

: To reduce the risk of fire or electric shock, do not expose this apparatus to rain or moisture. Apparatus shall not be exposed to dripping 

or splashing and no objects filled with liquids, such as vases, shall be placed on the apparatus.

NOTE

: This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 of the FCC Rules. 

These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses 
and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio 
communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful 
interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct 
the interference by one or more of the following measures:
• Reorient or relocate the receiving antenna.
• Increase the separation between the equipment and receiver.
• Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
• Consult the dealer or an experienced radio/TV technician for help.

CAUTION

: Changes or modifications not expressly approved by Rane Corporation could void the user's authority to operate the equipment.

This Class B digital apparatus complies with Canadian ICES-003.
Cet appareil numérique de la classe B est conforme à la norme NMB-003 du Canada.

WARNING

: This product may contain chemicals known to the State of California to cause cancer, or birth defects or other reproductive harm.
