NOTES ON CHIP COMPONENT REPLACEMENT

• Never reuse a disconnected chip component.

• Notice that the minus side of a tantalum capacitor may be dam­aged by heat.

FLEXIBLE CIRCUIT BOARD REPAIRING

• Keep the temperature of soldering iron around 270 °C during repairing.

• Do not touch the soldering iron on the same conductor of the circuit
board (within 3 times).

• Be careful not to apply force on the conductor when soldering or unsol­dering.

SAFETY CHECK-OUT

After correcting the original service problem, perform the following safe­ty check before releasing the set to the customer:
Check the antenna terminals, metal trim, “metallized” knobs, screws, and
all other exposed metal parts for AC leakage.
Check leakage as described below.

LEAKAGE TEST

The AC leakage from any exposed metal part to earth ground and from all
exposed metal parts to any exposed metal part having a return to chassis,
must not exceed 0.5 mA (500 microamperes.). Leakage current can be
measured by any one of three methods.

1. A commercial leakage tester, such as the Simpson 229 or RCA WT-

540A. Follow the manufacturers’ instructions to use these instru­ments.

2. A battery-operated AC milliammeter. The Data Precision 245 digital

multimeter is suitable for this job.

3. Measuring the voltage drop across a resistor by means of a VOM or

battery-operated AC voltmeter. The “limit” indication is 0.75 V, so
analog meters must have an accurate low-voltage scale. The Simpson
250 and Sanwa SH-63Trd are examples of a passive VOM that is
suitable. Nearly all battery operated digital multimeters that have a 2
V AC range are suitable. (See Fig. A)

A solda livre de chumbo tem as seguintes caracteristicas:

• Derrete a uma temperatura 40 °C maior que a solda comum.

Ferros de solda comuns podem ser usados mas a ponta tem que

ser aplicada sobre a solda por um tempo maior.

Ferros de solda com ajuste de temperatura devem ser ajustados

no valor de 350 °C.
Atenção: A impressao da placa (trilhas de cobre) pode se soltar

MODO DE TESTE DO DIPLAY DE FLUORESCENTE

This mode is used to check the À uorescent indicator tube, LEDs,
keys, [MASTER VOLUME] jog, [OPERATION DIAL] jog, mod­el, destination and software version.

Procedure:

1. Press [x], button, [METER MODE] button and [DISC SKIP/
EX-CHANGE] button simultaneously.

2. All LEDs and segments in À uorescent indicator tube are light-
ed up.

3. When you want to enter to the software version display mode,
press [DISC 1] button. The model information appears on the
À uorescent indicator tube.

• “GVX 7S” is shown for MHC-GTR88.

Press [DISC 1] button again to view the destination

information.

4. During the destination information display, press [DISC 1]
button. Each time [DISC 1] button is pressed, the À uorescent
indicator tube shows the version of each category software in

THIS NOTE IS COMMON FOR PRINTED WIRING BOARDS AND SCHEMATIC DIAGRAMS.
(In addition to this, the necessary note is printed in each block.)

For Printed Wiring Boards.

Note:

• X : Parts extracted from the component side.

• Y : Parts extracted from the conductor side.

• f : Internal component.

• : Pattern from the side which enables seeing.
(The other layers’ patterns are not indicated.)

Caution:

• DMB19 board is multi-layer printed board.
However, the patterns of intermediate layers have not

been included in diagrams.

• Indication of transistor.

For Schematic Diagrams.

Note:

• All capacitors are in F unless otherwise noted. (p: pF) 50

WV or less are not indicated except for electrolytics and
tantalums.

• All resistors are in  and 1/4 W or less unless otherwise

speci¿ ed.

• f : Internal component.

• 2 : NonÀ ammable resistor.

• 5 : Fusible resistor.

• C : Panel designation.

Note: The components identi¿ ed by mark 0 or dotted

line with mark 0 are critical for safety.

Replace only with part number speci¿ ed.

• A : B+ Line.

• B : B– Line.

• Voltages and waveforms are dc with respect to ground
under no-signal (detuned) conditions.

• Voltages are taken with VOM (Input impedance 10 MΩ).

Voltage variations may be noted due to normal production

tolerances.

• Waveforms are taken with a oscilloscope.

Voltage variations may be noted due to normal production

tolerances.

• Circled numbers refer to waveforms.
