IMPORTANT SAFETY INSTRUCTIONS

For the continued safety of yourself and others we recommend that you read the following 

safety and installation instructions. Keep this document in a safe location for future reference. 

Please heed all warnings and follow all instructions.

Do 

not 

use this equipment in a location where it might become wet. Clean only with a damp 

cloth.

This equipment may be installed in an industry standard equipment rack. We recommend that 

all mounting holes be used, providing the best physical support. The equipment may be used as 

a table top device, although stacking of the equipment is dangerous and not recommended.

Do not directly block any of the ventilation openings. If rackmounting, please provide adequate 

ventilation. Equipment may be located directly above or below this unit, but note that 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 equipment.

Protect the power cord and plug from damage caused by being walked on or pinched. Protect 

the line cord, where it exits the unit, from excessive strain. Only use attachments and acces-

sories specified by Rane.

Unplug this equipment during lightning storms or when unused for long periods of time.

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 damage, spilled liquid, fallen 

objects into an opened chassis, exposure to rain or moisture, a dropped unit, or abnormal 

operation.
