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 leadfree 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.

Step 2: Setting the Clock

You need to set the clock to use the alarm function or record the date and time. Clock setting display appears when you insert battery for the first time, or when you insert battery after the unit has been without battery for a certain period of time. In this case, proceed from step 4.

Turn the jog lever toward MENU.

The menu mode will be displayed in the display window.

Press the jog lever up (>) four times to select “DATE&TIME”.

Press the jog lever (x•B).

The date and time setting window is displayed. The year digits will flash.

TEST MODE

[Setting Method of the Test Mode]

There are two different methods to enter the test mode: (1) T o enter the test mode, turn on the HOLD switch while pressing

the STOP key and VOLUME+ key at the same time with the power on.

(2) While pressing the VOLUME- key, turn on the power in state

that the test land (TP7105) on the main board (side A) is shorted to GND.

[Exiting Method of the Test Mode]

Exit the test mode by turning off the power.

[Initial Status of the Test Mode]

When the test mode is set, the LCD display appears as shown below .
