Parts for your MARANTZ equipment are generally available to our National Marantz Subsidiary or Agent. ORDERING PARTS : Parts can be ordered either by mail or by Fax. In both cases, the correct part number has to be specifi ed. The following information must be supplied to eliminate delays in processing your order : 1. Complete address 2. Complete part numbers and quantities required 3. Description of parts 4. Model number for which part is required 5. Way of shipment 6. Signature : any order form or Fax. must be signed, otherwise such part order will be considered as null and void.SHOCK, FIRE HAZARD SERVICE TEST : CAUTION : After servicing this appliance and prior to returning to customer, measure the resistance between either primary AC cord connector pins ( with unit NOT connected to AC mains and its Power switch ON ), and the face or Front Panel of product and controls and chassis bottom. Any resistance measurement less than 1 Megohms should cause unit to be repaired or corrected before AC power is applied, and verifi ed before it is return to the user/customer. Ref.

Mode 0 (display “P 00”)Condition: FOCUS OFF, SPINDLE OFF, RADIALOFF, MUTE ON While pressing (Remote Control unit only) button,the sledge moves outside.And, release from this button. The sledge return toneutral position. Press NEXT button, the function will change to“Mode 1”.3. Mode 1 (display “P 01”)Condition: FOCUS ON, SPINDLE OFF, RADIAL OFF,MUTE ON Press NEXT button, the function will change to“Mode 2”. Press PREV button, the function will change to“Mode 0”.4. Mode 2 (display “P 02”)Condition: FOCUS ON, SPINDLE ON, RADIAL OFF,MUTE ON Press NEXT button, the function will change to“Mode 3”. Press PREV button, the function will change to“Mode 1”.5. Mode 3 (display “P 03”)Condition: FOCUS ON, SPINDLE ON, RADIAL ON,MUTE OFF Press PREV button, the function will change to“Mode 2”.The following button operations are available at theService Mode.1) While pressing STOP button, FL display shows allsegments.2) Press PAUSE button. FL display shows eachsegments one by one automatically. (Segments testmode) And, press PAUSE button again, this mode willbe stopped.3) The same as Normal operation is performed bypressing PLAY button. (Except segments test mode.)However if some default is detected, display shows anerror code. (For example: “Err 10”) Refer to the “Table1 ERROR CODE”.6.
