Page 2: Safety Information
SAFETY INFORMATION 1. Parts that have special safety characteristics are identified by the symbol on schematics or by special notes in the part lists. Use only replacement parts that have critical characteristics recommended by the manufacturer. 2. Make leakage current or resistance measurements to determine that exposed parts are acceptably insulated from the supply circuit before returning the unit to the customer. -

Page 26: Zone 2 Speaker Connections Less Than 3.2
Ω ZONE 2 SPEAKER CONNECTIONS LESS THAN 3.2 If a pre-installed speaker system is connected to the Zone 2 amplifier and it measures less than 3.2 Ω (DC resistance), add resistors according to the table below before operating the system. This will prevent the amplifier's short circuit protection from activating during loud music. -
