To initialize the unit 1. Press and hold down VCR/DVR button, then press ON/STANDBY button when the unit
5、is powered on. 2. After Clear is displayed, the preset memory and each mode stored in the memory are initialized and will return to the factory settings, and turn to Standby mode. 3.

6、model (U.S.A. model only) After correcting the original service problem, perform the following safety check before releasing the unit to the customer. Leakage current Check Measure the leakage current to a known earth ground (water pipe or conduct etc.) by connecting a leakage current tester between
7、 the earth ground and exposed metal parts of the unit (input/output ground terminals, screw heads or metal overlays etc.). Plug the power supply cord directly into a 120Vac 60Hz wall socket and turn ON/STANDBY button on. Any current measured must not exceed 0.5mA. This model uses a EE-PROM IC in ord
8、er to retain radio presets and other settings. So, memory contents will be kept eternally with no care. 4. Memory Backup 3. Remove the AC cord from power line. F6901 FUSE 12A-TUL-250V 1 252301GR !
