CAUTION HANDLING MEMORY MODULES
When handling inserting memory modules, sure touch components modules, such memory ICs, chip capacitors chip resistors. necessary avoid undue mechanical stress these components prevent damaging them. particular, push module cover drop modules order protect from mechanical defects, which would electrical defects. When re-packing memory modules, sure modules touching each other. Modules contact with other modules cause excessive mechanical stress, which damage modules.

NOTES CMOS DEVICES
PRECAUTION AGAINST DEVICES
Exposing devices strong electric field cause destruction gate oxide ultimately degrade devices operation. Steps must taken stop generation static electricity much possible, quickly dissipate when once occurred. Environmental control must adequate. When dry, humidifier should used. recommended avoid using insulators that easily build static electricity. devices must stored transported anti-static container, static shielding conductive material. test measurement tools including work bench floor should grounded. operator should grounded using wrist strap. devices must touched with bare hands. Similar precautions need taken boards with semiconductor devices
HANDLING UNUSED INPUT PINS CMOS DEVICES
connection CMOS devices input pins cause malfunction. connection provided input pins, possible that internal input level generated noise, etc., hence causing malfunction. CMOS devices behave differently than Bipolar NMOS devices. Input levels CMOS devices must fixed high using pull-up pull-down circuitry. Each unused should connected with resistor, considered have possibility being output pin. unused pins must handled accordance with related specifications.
STATUS BEFORE INITIALIZATION DEVICES
Power-on does necessarily define initial status devices. Production process does define initial operation status device. Immediately after power source turned devices with reset function have been initialized. Hence, power-on does guarantee output levels, settings contents registers. devices initialized until reset signal received. Reset operation must executed immediately after power-on devices having reset function.
