•
While working on the system, do not wear loose clothing such as neckties and
unbuttoned shirt sleeves, which can come into contact with electrical circuits or be
pulled into a cooling fan.
•
Remove any jewelry or metal objects from your body, which are excellent metal
conductors that can create short circuits and harm you if they come into contact with
printed circuit boards or areas where power is present.
•
Replace the on-board battery only with the same battery or an equivalent type of
battery recommended by the manufacturer. Dispose of used batteries according to
the manufacturer's instructions.
Danger: Installing the on-board battery upside down, which reverses its polarities,
creates a risk of explosion. Take care to install the battery correctly.
•
Only trained service technicians can replace the self-resetting PTC (positive
temperature coefficient) fuses on the main board, using only new fuses that are the
same as or equivalent to the ones being replaced. Contact Technical Support for
details and support.
Electrostatic Discharge Precautions
Electrostatic discharge (ESD) is generated by two objects with different electrical charges
coming into contact with each other. An electrical discharge is created to neutralize this
difference, which can damage electronic components and printed circuit boards. The
following measures are generally sufficient to neutralize this difference before contact
is made to protect your equipment from ESD:
•
Use a grounded wrist strap designed to prevent static discharge.
•
Keep all components and printed circuit boards (PCBs) in their antistatic bags until
ready for use.
•
Touch a grounded metal object before removing the board from the antistatic bag.
•
Do not let components or PCBs come into contact with your clothing, which might
retain a charge even if you are wearing a wrist strap.
•
Handle a board by its edges only; do not touch its components, peripheral chips,
memory modules, or contacts.
•
When handling chips or modules, avoid touching their pins.
•
Put the main board and peripherals back into their antistatic bags when not in use.
