Last Updated: May 02, 2019 12:16PM IST

Make a Call with the Iridium 9555 Satellite Phone -

Watch this video and read our tips for making your first phone call as well as muting your call and using the speakerphone feature: 

Muting your Call

For privacy during a call, use the mute feature. You hear the party on the other end, but they do not hear you.

Using the Speakerphone Function

To allow a call to be shared with other people within close proximity to your phone, use the speaker phone feature. In this mode the speaker in the rear of the phone is used instead of the normal earpiece/receiver.



The speaker volume can be adjusted either while on a call or with the Volume and Tones menu located under the Setup menu.
  1. Increase the speaker volume by pressing the Upper Volume Control key, during a call.
  2. Decrease the speaker volume by pressing the Lower Volume Control key, during a call.
  3. Once you are satisfied with the volume press OK.
  4. If you would like to cancel the change to the volume press Back.
As you press the keys, you hear the new volume level. The bar graph on the display indicates the volume level; the higher the graph, the louder the volume.
