UNPACKING AND PLACEMENT

INITIAL INSPECTION

Inspect the shipping container for damage. If any portion of the shipping container, packing 
material, ampli

fi

er, or accessories are damaged or missing, notify your dealer and the shipper 

(if a claim is to be made) immediately.

NOTE: MANY SHIPPERS REQUIRE NOTIFICATION AND INSPECTION WITHIN 24 HOURS OF DELIVERY TO 
DETERMINE THE NATURE OF DAMAGES INCURRED.

Your 

MODEL 525

 has undergone extensive performance evaluations, listening tests, quality 

control inspections, and a minimum 72-hour burn-in period prior to shipment and should 
therefore be in perfect operating condition upon delivery. If the ampli

fi

er does not operate 

correctly, please notify your dealer immediately.

We strongly suggest that you save all of the packing materials. If the ampli

fi

er is returned to 

your dealer or Je

 Rowland Design Group, the original packing materials must be used for 

shipment to avoid possible damage. Neither Je

 Rowland Design Group nor the shipper can 

be held responsible for damages incurred during transit if the original factory packing is not 
used. All factory returns require that Je

 Rowland Design Group issue a Return Authorization 

(RA) number prior to shipment.

UNPACKING

Carefully unpack ampli

fi

er chassis and power supply from original packing box. Remove all 

accessory items from the accessory box. Accessories include:

1 Detachable IEC AC Power Cord

Operational Manual

Warranty Card

IMPORTANT: RETAIN ALL PACKING MATERIALS FOR FUTURE TRANSPORT. SHIPPING PRODUCT IN 

INADEQUATE PACKING MATERIALS MAY VIOLATE THE JEFF ROWLAND DESIGN GROUP MANUFACTURER’S 

WARRANTY.
