All ICs and many other semi-conductors 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 wrist wrap with resistance. Keep components and tools also at this potential.

Tous les IC et beaucoup d’autres semi-conducteurs sont sensibles aux décharges statiques (ESD). Leur longévité pourrait être considérablement écourtée par le fait qu’aucune précaution n’est prise à leur manipulation. Lors de réparations, s’assurer de bien être relié au même potentiel que la masse de l’appareil et enfiler le bracelet serti d’une résistance de sécurité. Veiller à ce que les composants ainsi que les outils que l’on utilise soient également à ce potentiel.

WARNUNG

Alle ICs und viele andere Halbleiter sind empfindlich gegenüber elektrostatischen Entladungen (ESD). Unsorgfältige Behandlung im Reparaturfall kan die Lebensdauer drastisch reduzieren. Veranlassen Sie, dass Sie im Reparaturfall über ein Pulsarmband mit Widerstand verbunden sind mit dem gleichen Potential wie die Masse des Gerätes. Bauteile und Hilfsmittel auch auf dieses gleiche Potential halten.

NL

Alle IC’s en vele andere halfgeleiders zijn gevoelig voor electrostatische ontladingen (ESD). Onzorgvuldig behandelen tijdens reparatie kan de levensduur drastisch doen verminderen. 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.

Tutti IC e parecchi semi-conduttori sono sensibili alle scariche statiche (ESD). La loro longevità potrebbe essere fortemente ridatta in caso di non osservazione della più grande cauzione alla loro manipolazione. Durante le riparazioni occorre quindi essere collegato allo stesso potenziale che quello della massa dell’apparecchio tramite un braccialetto a resistenza. Assicurarsi che i componenti e anche gli utensili con quali si lavora siano anche a questo potenziale.

Warning!

–Use only the supplied speakers. The

combination of the main unit and

speakers provides the best sound. Using

other speakers can damage the unit and

sound quality will be negatively affected.

–Never make or change connections

with the power switched on.

–Connect the AC power cord to the

power outlet only after you have finished

hooking up everything.

–To avoid overheating of the system, a

safety circuit has been built in. Therefore,

your system may switch to Standby

mode automatically under extreme

conditions. If this happens, let the system

cool down before reusing it (not available for

all versions).

Step 1: Connecting FM/MW

antennas

–Place the MW loop antenna on a shelf or

attach it to a stand or wall.

– Extend the FM antenna and fix its ends to the

wall.

– Adjust the position of the antennas for

optimal reception.

–Position the antennas as far as possible from a

TV, VCR or other radiation source to prevent

unwanted noise.

– For better FM stereo reception, connect the

external FM antenna.

Step 2: Connecting the speakers

Connect the speaker wires to the SPEAKERS

terminals, right speaker to “R” and left speaker to

“L”, coloured (mar ked) wire to “+” and black

(unmarked) wire to “-”. Fully insert the

stripped portion of the speaker wire into the

terminal as shown on page 10.

Notes:

– Ensure that the speaker cables are correctly

connected. Improper connections may damage the

system due to short-circuit.

– Do not connect more than one speaker to any

one pair of +/- speaker terminals.

Step 3: Connecting to the game

console

IMPORTANT!

Gameport inputs are for the game

console only.

a.

Use the game console’s video cable (not

supplied) to connect its video output to the

GAMEPORT-VIDEO terminal.

b.

Use the game console’s audio cables (not

supplied) to connect its audio outputs to the

GAMEPORT-AUDIO L. / AUDIO R.

terminals.

c.

Use the video cable (yellow) to connect the

VIDEO OUT terminal to the video input on

the TV for viewing.

Notes:

– On the TV, the Video Input jack is usually yellow

and might be labeled A/V In, CVBS, Composite or

Baseband.

–To avoid magnetic interference, do not position

the front speakers too close to your TV.

Step 4: Connecting the AC

power cord

“AUTO INSTALL - PRESS PLAY”may appear

on the display panel when the AC power cord is

plugged into the power outlet for the first time.

Press ÉÅ on the main unit to store all available

radio stations (page 3 - P3) or press Ç to exit

(refer to “Tuner Operations”).

Repair Hint

1) During repair it is possible to disconnect the Tuner Board and CDC Module completely unless the fault is suspected to be in that area. This will not affect the performance of the rest of the set.

2) Due to the short flex cable wires in the ETF Module, the PCB should be disconnected and reconnected on the reverse side of the tape mechanism to keep it electrically connected during repair. see Figure 19.

Note: The flex cables are very fragile, care should be

taken not to damage them during repair. After repair, be very sure that the flex cables are inserted properly into the flex sockets before encasing, otherwise faults may occurs.
