    Component Polarity: Always check the polarity of connections and components before soldering. Particular attention must be paid to IC.s, diodes, transistors, capacitors and any other semiconductor device that is polarity dependent. Electrostatic Damage (ESD): NEC Confidential & Proprietary...
  • Page 5 Storage of Faulty Components: Any components that are replaced due to failure should be kept safely in an anti- electrostatic container. NEC’s Quality or Research & Development Departments may require them to make quality and reliability investigations. No Fault Found Equipment: In some cases the reported symptom may not be apparent.
  • Page 6 Electrical Safety: Electrical equipment is hazardous if misused. Any repairs must be carried out with care and only by authorised personnel. Ensure all power sources are switched off and power cords removed before undertaking any repairs. NEC Confidential & Proprietary...
  • Page 7 Never dispose of the battery pack in fire or water. Confidentiality: The circuitry within this equipment contains several components that are regarded as company confidential. Only use NEC specified parts as replacements. RF Injury: To avoid RF injury, direct exposure to radio frequency energy should be avoided. In particular, exposed parts of your body (especially the eyes and face) should not come into contact with the antenna while the equipment is transmitting.
