12. Notes on the temperature protection

The temperature protection is set considering the use temperature range of eNAND. If the temperature reaches the detection temperature shown below, the operation stops (ASENS is disabled).

Detection temperature on low temperature side: -25°C, return temperature: -20°C Detection temperature on high temperature side: 86.5°C, return temperature: 80°C

13. Control of FAN

There is the control of STOP, low rotation and high rotation. The temperature (eNAND, DVD mechanism) are detected and controlled it.

14. Pay attention to the wiring of BT cable. (It affects the sensitivity of BT antenna)

15. EJECT LOCK MODE for DVD mechanism

In order to change the EJECT LOCK/UNLOCK status of the mechanism, please perform following procedure.

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 C. Therefore, for lead-free soldering, the tip temperature of a soldering iron must be set to around 373 C 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.

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.

Check 12:How to judge whether the flash memory has reached its life or not.

If the reaction to user operation is slow or operation is slow in general, there is a possibility that the flash memory has reached its life. Make judgment regarding the flash memory life by looking at the display of the LD power on time mode.

1. Let the LD energizing time displayed. (Refer to the LD power on time mode for the method of displaying the LD energizing time.)

2. If the second digit from the left of the energizing time display is showing E, such as “ E ”, it means that the flash memory has reached its life.
