Request to Our Customers
Concerning the application range of our products
All of our products use general-use components. Therefore, please refrain from using them for fields requiring high reliability and for the
purposes dealing with human life.
Product warranty period
We maintain or exchange for free our product which broke naturally during normal use only within one year after its shipment. If there is
clear maintenance or exchange of a naturally broken product, please send the product to us.
On-site service and field costs and expanded damage
Our maintenance service is limited to inside our HQ. We will not accept any payment request of a maintenance cost which seems to be
caused by on-site maintenance by our employee or our product. If you request for our employee to be sent, we will charge for the
maintenance cost set separately. Our products are half products whose specific purpose or usage environment cannot be limited. We
cannot compensate for any damage caused by using our product, either.
Shipment to a distant place
When shipping any device using our product to a distance place such as overseas, a specific procedure regulated by the Trade Administration
Order is necessary. Because we have necessary materials for the procedure, please request them when you export our product. Also,
because we cannot support the maintenance of any product shipped to a distance place as stated above, please place the responsibility of
maintenance upon the user.
Reliability of battery backup
Although the nominal life of a lithium battery is more than five years, there are very rare instances where the battery life becomes
significantly short due to defects of the battery maker or others. Also, retaining data by a battery is not perfect in principle. Although there
is an extremely low probability, data can be lost (lightning, photographic strobe, and exposure to radiant rays). Also, there are instances
where data are lost due to dew forming during normal transportation, and due to vibrations and extreme humidity occurring during export/
import. When there is worry of program loss or when moving to a distant place where there is no technical staff to perform proper
maintenance, please convert the program to a ROM. We cannot be responsible for the program loss.
Abolishment of Freon
Accompanying the abolishment of Freon, cleaning of our products is gradually shifting to the no-cleaning method. When a board looks
like it is not clean, we have been using a non-cleaning type flux. There is no influence on the specification and performance. Because this
is a measure from the standpoint of environmental protection, we ask for your understanding.
Specification change
Since 1996, there has been production discontinuation of 80-system ICs such as 8255 and 8251 one after another. Although we have
been changing designs and taking measures each time to keep the compatibility current, part of normally-unused functions etc. may be
changed. Please understand this in advance.
Flash ROM
In November 1996, we adopted flash ROMs. The number of warranted rewriting of a flash ROM is 100,000 times, and the data retaining
period is 10 years (same specification as EPROM). Also, because flash ROM may be damaged if the power is cut off while its contents are
being erased or rewritten, please use it in a stable power environment during a time of maintenance.
* Standards and specifications may be changed without prior announcement.
