  • Page 7: Charging The Handsets

    NOTE: The handsets (batteries) are partially charged at the factory and normally need not be charged prior to initial use of the NOMAD Pro 2. However, if the system has been in long-term storage prior to initial use, handsets must first be fully charged before attempting to take X-rays.

  • Page 8: Safety Precautions

    • Do not enable the NOMAD Pro 2 until patient and operator are positioned and ready for the exposure, preventing interruption and inadvertent exposure of anyone to X-rays.

  • Page 11: Usage And Duty Cycle

    2.2 Usage and Duty Cycle As a safety feature, the NOMAD Pro 2 will not emit X-rays with insufficient voltage (low battery). The NOMAD Pro 2 is also designed to avoid damage from overheating. The minimum duty cycle rating for maximum exposure (the relationship between duration and frequency of exposures taken during a rolling 60 second period) is 1:60.

  • Page 12: Security, Storage, And Transportation

    2.4 Security, Storage, and Transportation • Do not store the NOMAD Pro 2, handsets, charging cradle, or AC power supply in extreme conditions: below –20°C (–4°F) or above +60°C (+140°F), or beyond 95% relative humidity (non-condensing). The optimal storage location is cool, dry, and away from direct sunlight.
