2. Precautions
2.1. Safety Precautions
In order to use this product safely, please take special note of the following precaution.
This product uses semiconductor components designed for generic electronics
equipment such as office automation equipment, communications equipment,
measurement equipment and machine tools. Do not incorporate the product into
devices such as medical equipment, traffic control systems, combustion control
systems, safety equipment and so on which can directly threaten human life or pose
a hazard to the body or property due to malfunction or failure. Moreover, products
incorporating semiconductor components can be caused to malfunction or fail due
to foreign noise or surge. To ensure there will be no risk to life, the body or property
even in the event of malfunction or failure, be sure to take all possible measures in
safety system design, such as using protection circuits like limit switches or fuse
breakers, or system redundancy.
2.2. Handling Precautions
Please pay attention to the following points when handling the product in order to avoid causing any irreversible damage.
Areas Easily Damaged
The microSD connector and its cover and the connectors of the flat cable
connecting Armadillo-440 and the LCD Expansion Board can be easily damaged.
Please be careful not to damage them by handling them with too much force.
Modifications To This Product
Please take note that any modifications
[1]
made to this product are not covered
under warranty. Also, please ensure to undertake a full operational check of this
product before carrying out any modifications or mounting connectors
[2]
.
Mounting and Dismounting of
Connectors While Powered On
Apart from hot-pluggable interfaces (LAN, USB, Mic, Headphone), do not under
any circumstances add or remove connectors while power is supplied to this
product or peripheral circuits.
Static Electricity
As CMOS devices are used in this product, please store it in antistatic packaging
(such as that it was shipped in) until time of use.
Latch-up
Excessive noise or a surge from the power supply or input/output, or sharp voltage
fluctuations can lead to the CMOS devices incorporated in the board causing a
latch-up. Once the latch-up occurs, this situation continues until the power supply
is disconnected, and therefore can damage the devices. Measures such as adding
a protection circuit to noise-susceptible input/output lines or not sharing the
power supply with devices that can be the cause of noise are highly recommended.
Physical Stress
Please avoid strong physical stress such as drops or other impacts.
[1]
With the exception of adding connectors to unmounted interfaces.
[2]
When mounting connectors, please ensure to apply masking, avoid solder residue coming in contact with surrounding parts and avoid creating solder balls.
