Flexible Circuit Board Repairing
•Keep the temperature of the 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.
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.
•UNLEADED SOLDER
Boards requiring use of unleaded solder are printed with the lead-
free mark (LF) indicating the solder contains no lead.
(Caution: Some printed circuit boards may not come printed with
the lead free mark due to their particular size.)
: LEAD FREE MARK
Unleaded solder has the following characteristics.
•Unleaded solder melts at a temperature about 40°C higher than
ordinary solder.
Ordinary soldering irons can be used but the iron tip has to be
applied to the solder joint for a slightly longer time.
Soldering irons using a temperature regulator should be set to
about 350°C.
Caution: The printed pattern (copper foil) may peel away if the
heated tip is applied for too long, so be careful!
•Strong viscosity
Unleaded solder is more viscous (sticky, less prone to flow)
than ordinary solder so use caution not to let solder bridges
occur such as on IC pins, etc.
•Usable with ordinary solder
It is best to use only unleaded solder but unleaded solder may
also be added to ordinary solder.

TEST MODE
1. Outline of the TEST MODE
The TEST MODE is designed to help verify the set when servicing
it.
The TEST MODE is only menu driven to select modes for servicing.
2. Entering and Canceling the TEST MODE
With the power on, turn on the [HOLD] switch while pressing the
xSTOP button and the •DISPLAY/MENU button at the same time.
3. Canceling the TEST MODE
The TEST MODE can be cancelled by turning off the power
(unplugging the dry battery).
4. Menu Key Designation
The menu has the five modes described below. The following keys
are assigned on the initial screen (version display).
5. Key Assignment
From within TEST MODE, the intended menu can be entered by
using the appropriate one key of the following key.

5-2. LCD Test
To enter the LCD Test, press the •DISPLAY/MENU button. The LCD
Test has two modes: All On and All Off First all the indicators are
on. All the indicators are off when the button is pressed again.
Press the xSTOP button to return to the initial display (destination
information, memory capacity, CPU FW information and MIC sens).
5-3. BEEP Test
To enter the BEEP Test, press the FM • i/5 button.
Press the xSTOP button to return to the initial screen (memory and
CPU version).
5-4. DSP LOOP
The DSP LOOP modes can be entered selectively by pressing the
appropriate one of the following three keys.
Within the LOOP test menu, “LOOP” is displayed. The sensitivity
character H or L is displayed depending on the position into which
the [HOLD] switch is placed.
The sensitivity H is displayed when [HOLD] switch is in the ON
position. The sensitivity L is displayed when [HOLD] switch is in
the OFF position.
To change the DSP LOOP test mode, press the xSTOP button, then
select the zX REC/PAUSE button, –.button, or >+button.
In a DSP Test mode, to select another DSP Test mode and to select
the other sensitivity, the xSTOP button also has to be pressed.

To change the sensitivity again, press the xSTOP button and change
the [HOLD] switch.
In a DSP Test mode, changing the mode and changing the sensitivity
require the xSTOP button be pressed.
5-5. USB Test
In this test, the ON/OFF status of VBUS is displayed and the
SUSPEND test is performed.
The Nx PLAY/STOP(ENTER) button is pressed to display the status of
VBUS by “On” or “OFF” indication.
With the VBUS ON, the [HOLD] switch is operated (ON) to perform
the SUSPEND test.
• VBUS Test
• SUSPEND Test
With the VBUS ON, turn the [HOLD] switch ON to enter the
SUSPEND mode.
When this mode is cancelled, the VBUS is turned OFF.
5-6. RESET MENU
To enter the RESET MENU test, press the [DIVIDE] button.
When all of the buttons or controls located on the set are operated,
the system shows “Ok” if all of them are normally operated.
An operation of a switch is indicated by the number for verification
in order to make a simple indication.
Note 1: When 10 different operations of the switches are normally
made in any order (regardless of the order that pushbuttons
are pressed and the slide switch is set to ON and OFF),
the system shows “Ok”.
Note 2: Clear memory when “ACCESS” is blinking on the display.
(Do this before “Ok” is shown.) To exit from this menu,
the power has to be turned off (battery to be removed).
