  • Check the signal strength meter. If signal is weak, move to an open space with clear line
    of sight. Force registration can be done via the phone by pressing the up arrow key, then pressing the 8 key. This will manually register the Iridium phone with the satellite system.

RF Signal Interference

  • All wireless devices are susceptible to RF (radio frequency) interference from other
    wireless devices. This problem is especially evident when numerous antennas and broadcasting devices are located within close proximity to each other ie. On a shipping vessel.
  • An Iridium handset within 10 meters to 52 meters of an operational non-Iridium Satellite terminal (including all types of non-Iridium satellite dishes and antennas) will likely experience degraded performance. The specific position of the terminal in relation to the Iridium handset will determine the amount degradation that might be expected.
  • Symptoms of RF interference often resemble those that arise when an Iridium phone is being operated with an obstructed view of the sky. Some of these symptoms include:
    o Erratic or no signal strength indicators o Dropped calls
    o Warbled voice
    o Iridium logo missing on the LCD
  • These symptoms may be intermittent or persistent depending largely on the interference source, distance, strength and frequency of broadcast.
