PRECAUTIONS NOTE: It is vital to read this section before using your REV7 Professional Digital Reverberator. This unit uses state-of-the-art digital technology which, although constructed for years of trouble-free use, requires careful handling. • VOLTAGE RATINGS Check that the AC supply in your area is appropriate for your REV7. U.S./Canadian Model: 110V - 120V, 50/60Hz. General Model: 220V - 240V, 50/60Hz. • ENVIRONMENTAL TEMPERATURE Do not expose the REV7 to excessive heat. The operating temperature range of this unit is between 0 and 40 degrees Centigrade (32 - 104 degrees Fahrenheit). • EXTERNAL CLEANING DO NOT clean the exterior of the REV7 with solvents such as benzine or paint thinner. Dust, dirt, or fingermarks should simply be removed with a soft, dry cloth. Internal cleaning of the unit should only be done by a qualified technician. • BACKUP BATTERY To ensure that User Programs are not lost when the REV7's power is turned off, a built-in Lithium battery acts as a backup. In normal use, this battery lasts 5 years, but it is advisable to change the battery before this time has elapsed. Contact your local Yamaha dealer for details. NOTE: When you change the battery, the User Programs may be lost. As a safeguard, you can note down the parameters of your User Programs in the USER PROGRAM TABLE accompanying this manual. You can then reprogram the REV7 after the new battery is installed. The preset programs are permanent, and will not be affected by a change of battery. • XLR TYPE CONNECTORS The XLR (Cannon) type Input and Output connectors are wired in the following configuration: Pin 1: GROUND. Pin 2: HOT. Pin 3: COLD. Ensure that all equipment connected to the REV7 matches this wiring.
