6.Setting the AM tuning step frequency
2. To initialize the unit
This device employs a microprocessor to perform various functions and operations. If interference generated by an external power supply, radio wave, or other electrical source results in accident which causes the specified operations and functions to operate abnormally. To perform a result, please follow the procedure below. 1.Press and hold down the VIDEO-1 button, then press the STANDBY/ON button. 2.After "clear" is displayed, the preset memory and each mode stored in the memory, such as surround, are initialized and will return to the factory setting. (Worldwide models only) You can switch the AM band tuning steps between 9 kHz and 10 kHz. The initial setting is 9 kHz. Please set the AM tuning step frequency to match the AM band tuning step frequency in your area. USA and Canadian models Other models 10 kHz 9 kHz

Press MEMORY while holding down TUNER. Note All the preset stations are erased when you switch the AM band tuning steps.

3. Safety-check out (Only U.S.A. model) After correcting the original service problem, perform the following safety check before releasing the set to the customer. Connect the insulating-resistance tester between the plug of power supply cord and screw on the back panel. Specifications: 3.3Mohm+/-10% at 500V.

4. Memory Preservation This unit does not require memory preservation batteries. A built-in memory po wer back-up system preserves the contents of the memory during power failures and even when the unit is unplugged.The unit must be plugged in order to charge the back-up system. The memory preservation period after the unit has been unplugged varies depending on climate and placement of the unit. On the average, memory contents are protected over a period of a few weeks after the last time the unit has been unplugged. This period is shorter when the unit is exposed to a highly humid climate.
