Safety Warnings

Before performing any of the tasks in this section, read the safety warnings in
page 7.
Preventing Electrostatic Discharge Damage
SD flash memory modules are sensitive to electrostatic discharge (ESD) damage, which can occur when electronic cards
or components are handled improperly, results in complete or intermittent failures.
To prevent ESD damage, follow these guidelines:

Always use an ESD wrist or ankle strap and ensure that it makes good skin contact.

Connect the equipment end of the strap to an unfinished chassis surface.

Place a removed the memory card on an antistatic surface or in a static shielding bag. If the card will be returned to
the factory, immediately place it in a static shielding bag.

Avoid contact between the card and clothing. The wrist strap protects the card from ESD voltages on the body only;
ESD voltages on clothing can still cause damage.

Do not remove the wrist strap until the installation is complete.
