1. Replacing the fuses
3. Safety-check out(Only U.S.A. model)After correcting the original service problem perform thefollowing safety check before releasing the set to the customerConnect the insulating-resistance tester between the plug ofpower supply cord and terminal GND on the back panel.Specifications: More than 10Mohm at 500V
This symbol located near the fuse indicates that thefuse used is show operating type, For continued protection againstfire hazard, replace with same type fuse , For fuse rating, refer to the marking adjest to the symbol.
Ce symbole indique que le fusible utilise est e lent. Pour une protection permanente, n'utiliser que des fusibles de meme type. Ce demier est indique la qu le present symbol est apposre.
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.
2. To initialize the unit
This unit does not require memory preservation batteries. A built-inmemory power back-up system preserves the contents of thememory during power failures and even when the unit is un-plugged.The unit must be plugged in order to charge the back-upsystem.The memory preservation period after the unit has been unpluggedvaries depending on climate and placement of the unit. On theaverage, memory contents are protected over a period of a fewweeks after the last time the unit has been unplugged. This pe-riodis shorter when the unit is exposed to a highly humid cli-mate.

REF. NO. PART NO. DESCRIPTION
This device employs a microprocessor to perform variousfunctions 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.
With the exception of the worldwide models, a tuning step selectorswitch is not provided. When you change the band step, changethe parts as shown below.
To 10kHz To 9kHzR7020 Open 10kR7021 10kohm 8.2kohm
4. Memory Preservation
7. Changing the AM band step
5.Setting the AM tuning step frequency (World wide models only)
6.Setting the voltage selector (Worldwide models only)
Worldwide models are equipped with a switch that controlsthe AM band tuning step. Please set this switch to match the AM band tuning step frequency in your area.
World models are equipped with a voltage selectorconform with local power supplies. Be sure to set this switch tomatch the voltage of the power supply in your area beforeplugging 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 screwdriverinto the groove in the switch. Slide the switch all the way to the right(120V) or to the left(220V-230V), whichever is appropriate.
