6.Setting the voltage selector
(Worldwide models only)
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 souce 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 the hold down the VIDEO 1 button , then press the SPEAKER A button when the nuit is Power 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.
World models are equipped with a voltage selector conform with local power supplies. Be sure to set this switch to match the voltage of the power supply in your area before plugging in the unit. Determine the proper voltage for your area: 230V or 120V. If the preset voltage is not correct for your area, insert a screwdriver into the groove in the switch. Slide the switch all the way to the right (120V) or to the left(220V-230V), whichever is appropriate.

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 terminal GND on the back panel. Specifications: More than 10Mohm at 500V
7. Changing the AM band step With the exception of the worldwide models, a tuning step selector switch is not provided. When you change the band step, change the parts as shown below. To 10kHz To 9kHz R7020 Open 10k R7021 10kohm 8.2kohm NADIS-7043 (Display circuit PC board) From soldering side
R7010 C7003
4. Memory Preservation
This unit does not require memory preservation batteries. A built-in memory power back-up system preserves the contents of the memory during power failures and even when the unit is un-plugged. 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 pe-riod is shorter when the unit is exposed to a highly humid cli-mate.
