[Important Check Points for Good Servicing] In this manual, procedures that must be performed during repairs are marked with the below symbol. Please be sure to confirm and follow these procedures. 1. Product safety Please conform to product regulations (such as safety and radiation regulations), and maintain a safe servicing environment by following the safety instructions described in this manual.
1. SERVICE PRECAUTIONS 1.1 SERVICE PRECAUTIONS 1. You should conform to the regulations governing the product (safety, radio and noise, and other regulations), and should keep the safety during servicing by following the safety instructions described in this manual. 2. Be careful in handling ICs. Some ICs such as MOS type are so fragile that they can be damaged by electrostatic induction.
3. BASIC ITEMS FOR SERVICE 3.1 CHECK POINTS AFTER SERVICING To keep the product quality after servicing, please confirm following check points. r i f Confirm whether the customer complain has The customer complain must not be been solved. reappeared. Audio and operations must be normal.
4. BLOCK DIAGRAM There is not information to be shown in this chapter. 5. DIAGNOSIS 5.1 TROUBLESHOOTING Output audio from the Speaker is switched by “AMP control terminal” (Blue/white cable) If the terminal signal is “L”, the audio from Mini-plug (AVIC-F500BT) is selected. If the terminal signal is “H”, Car stereo audio is selected.
7. DISASSEMBLY (Caution) 1) Approximately one hour after activating, the temperature on part of outer surface reaches nearly 70 C. Therefore, be careful not to get burn, immediately after turning off power. 2) Watch out for a hot heat sink. Operations while removing a heat sink can cause failure.
