MARANTZ DESIGN AND SERVICE
Using superior design and selected high grade components, MARANTZ company has created the ultimate in stereo sound.
Only original MARANTZ parts can insure that your MARANTZ product will continue to perform to the specifications for which
it is famous.
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 specified.
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 SERVICETEST :
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
verified before it is return to the user/customer.
Ref. UL Standard No. 1492.
In case of difficulties, do not hesitate to contact the Technical
Department at above mentioned address.

WARNING
GB WARNING
All ICs and many other semiconductors are susceptible to
electrostatic discharges (ESD). Careless handling during
repair can reduce life drastically.
When repairing, make sure that you are connected with the
same potential as the mass of the set via a wristband with
resistance. Keep components and tools at this potential.
F ATTENTION
Tous les IC et beaucoup d´autres semi-conducteurs sont
sensibles aux décharges statiques (ESD). Leur longévite
pourrait être considérablement écourtée par le fait qu´aucune
précaution nést prise àleur manipulation.
Lors de réparations, s´assurer de bien être reliéau même
potentiel que la masse de l´appareil et enfileer le bracelet
serti d´une résistance de sécurité.
Veiller àce que les composants ainsi que les outils que l´on
utilise soient également àce potentiel.
D WARNUNG
Alle ICs und viele andere Halbleiter sind empfindlich
gegenüber elektrostatischen Entladungen (ESD).
Unsorgfältige Behandlung im Reparaturfall kann die
Lebensdauer drastisch reduzieren.
Sorgen Sie dafür, daßsie im Reparaturfall über ein Puls-
armband mit Widerstand mit dem Massepotential des
Gerätes verbunden sind.
Halten Sie Bauteile und Hilfsmittel ebenfalls auf diesem
Potential.
NL WAARSCHUWING
Alle IC´s en vele andere halfgeleiders zijn gevoelig voor
electrostatische ontladingen (ESD).
Onzorgvuldig behandelen tijdens reparatie kan de levensduur
drastisch doen vermindern. Zorg ervoor dat u tijdens reparatie
via een polsband met weerstand verbonden bent met hetzelfde
potentiaal als de massa van het apparaat.
Houd componenten en hulpmiddelen ook op ditzelfde potentiaal.
I AVVERTIMENTO
Tutti IC e parecchi semi-conduttori sono sensibili alle scariche
statiche (ESD).
La loro longevitàpotrebbe essere fortemente ridatta in caso di
non osservazione della piùgrande cauzione alla loro
manipolazione. Durante le riparationi occorre quindi essere
collegato allo stesso potenziale che quello della massa
delápparecchio tramite un braccialetto a resistenza.
Assicurarsi che i componenti e anche gli utensili con quali si
lavora siano anche a questo potenziale.
