1. SERVICE PRECAUTIONS

1.1 NOTES ON SOLDERING

• For environmental protection, lead-free solder is used on the printed circuit boards mounted in this unit.
Be sure to use lead-free solder and a soldering iron that can meet specifications for use with lead-free solders for repairs
accompanied by reworking of soldering.
• Compared with conventional eutectic solders, lead-free solders have higher melting points, by approximately 40 ºC.
Therefore, for lead-free soldering, the tip temperature of a soldering iron must be set to around 373 ºC in general, although
the temperature depends on the heat capacity of the PC board on which reworking is required and the weight of the tip of
the soldering iron.
Do NOT use a soldering iron whose tip temperature cannot be controlled.
Compared with eutectic solders, lead-free solders have higher bond strengths but slower wetting times and higher melting
temperatures (hard to melt/easy to harden).
The following lead-free solders are available as service parts:
• Parts numbers of lead-free solder:
GYP1006 1.0 in dia.
GYP1007 0.6 in dia.
GYP1008 0.3 in dia.

1.2 BACKUP AND RESTORING OF USER DATA

Before repair, back up user data, following the backup procedures shown below.

1. Press the UTILITY key.
2. Press the function GENERAL key.
3. Select BACKUP MODE, by turning the rotary selector, then press the Select Down key or the rotary selector.
4. Select "Write to USB," by turning the rotary selector, then press the rotary selector.
5. The message "Connect a USB storage device to the USB port" is displayed. Insert a USB storage device.
6. Data copying starts.
When "Done" is displayed and the UTILITY screen is restored, data copying is complete.
Note:
A file named "BACKUP.BIN" of approx. 1.3 MBytes is created in the root directory of the USB storage device.
Restoring procedures
The user data copied to the USB storage device are written to the built-in memory of this product.
1. Press the UTILITY key.
2. Press the function GENERAL key.
3. Select BACKUP MODE, by turning the rotary selector, then press the Select Down key or the rotary selector.
4. Select "Read from USB," by turning the rotary selector, then press the rotary selector.
5. The message "Connect a USB storage device to the USB port" is displayed. Insert a USB storage device.
6. Data reading starts.
When "Done" is displayed and the UTILITY screen is restored, data reading is complete.
Note:
The data previously stored in the built-in memory are completely erased, and the data in the USB storage device will be
copied.
