Use RAM modules that comply with the specifications below. Using any other module may cause malfunction or result
in computer failure.
RAM module specifications:
DDR2 SDRAM, 172 pins, Micro DIMM, 1.8 V, PC2-4200
CAUTION
Use recommended RAM module products. Do not use non-recommended RAM modules. Non-recommended RAM
modules may not operate properly, and may cause damage to your computer. Some non-recommended RAM mod-
ules may overheat, causing the cover to warp. Refer to various sources for recommended RAM module.
RAM modules are extremely sensitive to static electricity. There are cases where static electricity generated by the
human body has adversely affected such RAM modules. When inserting or removing a RAM module, do not touch
the terminals or internal components, insert objects other than the module, or allow foreign particles to enter. Doing
so has been known to cause damage, fire or electric shock.
Matsushita Electric Industrial Co., Ltd. will bear no responsibility whatsoever for failures or damage caused by the
use of non-recommended RAM modules, or by incorrect installation or removal of such RAM modules. Before
installing a RAM module, confirm the product type and the correct installation method.
