4. DISASSEMBLY
4-1. Important
• Please note that the product on this manual may appear to be different from the actual one
according to the changes such as engineering design change.
• In order to prevent static and avoid leaving grease from the hand, wear conductive gloves,
finger cots, or anti-static band when assembling/disassembling the product.
• Do not use metal tweezers. Be sure to use plastic tweezers with flat tips.
(Anti-static tweezers are recommended)
• There are several kinds of screws. Be sure to use the correct type of screws when
reassembling. It is advisable to sort the screws as shown below after removing them.
• The disassembly and assembly procedure of the equivalent model SE-S3000 are used for
that of this model.
