SAFETY PRECAUTION

IMPORTANT SERVICE SAFETY PRECAUTION

WARNING1. For continued safety, no modification of any circuit should be

attempted.

2. Disconnect AC power before servicing.

BEFORE RETURNING THE RECEIVER (Fire &Shock Hazard)Before returning the receiver to the user, perform the followingsafety checks:

3. Inspect all lead dress to make certain that leads are not pinched,and check that hardware is not lodged between the chassis andother metal parts in the receiver.

4. Inspect all protective devices such as non-metallic control knobs,insulation materials, cabinet backs, adjustment and compartmentcovers or shields, isolation resistor-capacitor networks, mechanicalinsulators, etc.

5. To be sure that no shock hazard exists, check for leakage current inthe following manner.

Plug the AC cord directly into a 120 volt AC outlet.

Using two clip leads, connect a 1.5k ohm, 10 watt resistor paral-leled by a 0.15F capacitor in series with all exposed metal cabinetparts and a known earth ground, such as electrical conduit or elec-trical ground connected to an earth ground.

Use an AC voltmeter having with 5000 ohm per volt, or higher, sen-sitivity or measure the AC voltage drop across the resistor.

Connect the resistor connection to all exposed metal parts having areturn to the chassis (antenna, metal cabinet, screw heads, knobsand control shafts, escutcheon, etc.) and measure the AC voltagedrop across the resistor.

All checks must be repeated with the AC cord plug connectionreversed. (If necessary, a nonpolarized adaptor plug must be usedonly for the purpose of completing these checks.)

Any reading of 0.75 Vrms (this corresponds to 0.5 mA rms AC.) ormore is excessive and indicates a potential shock hazard whichmust be corrected before returning the monitor to the owner.

Ne peut effectuer la rparation qu' un technicien spcialis qui s'est parfaitement accoutum toute vrification de scurit et aux

conseils suivants.

N'entreprendre aucune modification de tout circuit. C'est danger-

eux.

Dbrancher le rcepteur avant toute rparation.

Inspecter tous les faisceaux de cbles pour s'assurer que les fils

ne soient pas pincs ou qu'un outil ne soit pas plac entre le chs-

sis et les autres pices mtalliques du rcepteur.

Inspecter tous les dispositifs de protection comme les boutons de

commande non-mtalliques, les isolants, le dos du coffret, les cou-

vercles ou blindages de rglage et de compartiment, les rseaux

de rsistancecapacit, les isolateurs mcaniques, etc.

S'assurer qu'il n'y ait pas de danger d'lectrocution en vrifiant la

fuite de courant, de la facon suivante:

Brancher le cordon d'alimentation directem-ent une prise de cou-

rant de 120V. (Ne pas utiliser de transformateur d'isolation pour

cet essai).

A l'aide de deux fils pinces, brancher une rsistance de 1.5 k

10 watts en parallle avec un condensateur de 0.15F en srie

avec toutes les pices mtalliques exposes du coffret et une terre

connue comme une conduite lectrique ou une prise de terre

branche la terre.

Utiliser un voltmtre CA d'une sensibilit d'au moins 5000/V pour

mesurer la chute de tension en travers de la rsistance.

Toucher avec la sonde d'essai les pices mtalliques exposes qui

prsentent une voie de retour au chssis (antenne, coffret mtalli-

que, tte des vis, arbres de commande et des boutons, cusson,

etc.) et mesurer la chute de tension CA en-travers de la rsistance.

Toutes les vrifications doivent tre refaites aprs avoir invers la

fiche du cordon d'alimentation. (Si ncessaire, une prise

d'adpatation non polarise peut tre utilise dans le but de termin-

er ces vrifications.)

La tension de pointe mesure ne doit pas dpasser 0.75V (corre-

spondante au courant CA de pointe de 0.5mA).

LC-32D47U/LC-32SB27U/LC-C3237UPRECAUTIONS FOR USING LEAD-FREE SOLDER

Employing lead-free solder PWBs of this model employs lead-free solder. The LF symbol indicates lead-free solder, and is attached on the PWBs and service manuals. The

alphabetical character following LF shows the type of lead-free solder.

Example:

Using lead-free wire solder When fixing the PWB soldered with the lead-free solder, apply lead-free wire solder. Repairing with conventional lead wire solder may cause dam-

age or accident due to cracks.

As the melting point of lead-free solder (Sn-Ag-Cu) is higher than the lead wire solder by 40 C, we recommend you to use a dedicated solderingbit, if you are not familiar with how to obtain lead-free wire solder or soldering bit, contact our service station or service branch in your area.

Soldering As the melting point of lead-free solder (Sn-Ag-Cu) is about 220 C which is higher than the conventional lead solder by 40 C, and as it has poor

solder wettability, you may be apt to keep the soldering bit in contact with the PWB for extended period of time. However, Since the land may bepeeled off or the maximum heat-resistance temperature of parts may be exceeded, remove the bit from the PWB as soon as you confirm thesteady soldering condition.

Lead-free solder contains more tin, and the end of the soldering bit may be easily corroded. Make sure to turn on and off the power of the bit asrequired.

If a different type of solder stays on the tip of the soldering bit, it is alloyed with lead-free solder. Clean the bit after every use of it.

When the tip of the soldering bit is blackened during use, file it with steel wool or fine sandpaper.

Be careful when replacing parts with polarity indication on the PWB silk.

Lead-free wire solder for servicing

Indicates lead-free solder of tin, silver and copper. Indicates lead-free solder of tin, silver and copper.
