SECTION 1PRECAUTION

This service manual does not describe PRECAUTION.

SECTION 2SPECIFIC SERVICE INSTRUCTIONS

2.1 CIRCUIT DESCRIPTIONLCD CircuitThe LCD module is connected to the connector (CN4) of the Sub (Display) unit. The LCD module is controlled using parallel interface(EMIF) from the MPU (IC706) of the transceiver main unit. The backlight of the LCD is controlled by the backlight driver (IC8). Thebacklight driver (BD1754HFN) has a single-line digital control interface (UPIC) that can control the power ON/OFF and LED currentvalue through the EN pin. The backlight driver is controlled by I/O Expander (IC10).

Indicator LED Circuit and Key BacklightIndicator LED and key backlight LED are controlled by I/O Expander (IC10). Indicator LED is consist of 3 color (Red, Green, Blue).

Key Detection CircuitIC10 is I/O port expander with keypad matrix decoder. It handles key scanning and flag the MPU (IC706) of the transceiver mainunit via an interrupt line when key events have occurred. It communicates with the MPU via I2C serial communication.

Light Sensor CircuitLight sensor (IC6) senses intensity of ambient light. The intensity value of ambient light is converted to digital signal and providedto the MPU (IC706) of the transceiver main unit via I2C serial communication.

Power Supply CircuitThe battery voltage (SB) is provided from the transceiver main unit via SB and SP interface connector (CN2). The battery voltage(SB) goes to 8 pin interface connector (J1). Other power supply (54M, 18M, 33M) is provided from the transceiver main unit via 50pin interface connector (CN6). 54M outputs 5.36V and goes to illumination circuit, AVR_IC (IC1). IC1 (50M) outputs 5.0V. 18M out-puts 1.8V and goes to LCD module. 33M outputs 3.3V and goes to AVR_IC (IC2). IC2 (30LCD) outputs 3.0V.

00) and holder (J1K-0019-00)(1) Remove the speaker lead from the holder hook. <1>(2) Remove the speaker connector from the display unit con-

nector (CN5). <2>(3) When removing the speaker hardware fixture, insert a flat-

head screwdriver at the position shown in Figure 1-1 andtilt it in the direction shown by the arrow. <3>

3.2 Precautions for Reassembly3.2.1 Installing the holder (J1K-0019-00) and speaker hard-

ware fixture (J2B-0023-00) (1) Insert two tabs of the holder (J1K-0019-00) into the hollows

in the top of the panel. <1>(2) Push the two tabs of the holder in on the opposite side of

those in step 1 above and fit them into the hollow in the bot-tom of the panel. <2>

Note:Push in the holder until it snaps in place.

(3) Install the speaker holder onto the panel. <3>

Note:To improve water resistance, fit the panel into the grooveof the holder.

(4) Place the speaker into the speaker holder.

Note:The speaker must not ride on the holder rib.

(5) Place the spacer on the speaker.(6) Insert the hardware fixture (J2B-0023-00) into the hollow of

the panel as shown in Figure 2-3, then push two parts ofthe hardware fixture and fit it into the hollow of the top of thepanel. (Fig. 2-3 <4>)
