PACKAGING FOR SHIPMENT
The SL40 circuit boards are subject to both mechanical and electrical damage when
improperly handled. These components must be packaged for shipment in anti-static
bags, to protect against electrostatic damage, and a sturdy protective box, to prevent
mechanical damage during shipment. Ideally, the component to be returned should be
packaged in the same shipping material that the replacement component is shipped in.
