4.7.1. System Check Out
The AirCell
®
ST 3100 system can be checked out while the aircraft is on the ground or if the aircraft is
outside (clear view of sky).
Lift the Handset from the cradle and observe the following:
•
Verify an illuminated display and that the display indicates “IRIDIUM”, and the “NOSVC” indication
is out (this usually takes about 30 seconds if the antenna has a clear view of sky).
•
Place a call by entering 9 + country code + phone number on the keyboard and then press
SND
.
Example: 9 + 1 303 379 0278 SND, this will call AirCell
®
Customer Service.
•
Verify that the system is providing a clear communications link, and then press
END
to terminate
the call.
•
If multiple Handsets are installed, repeat the above procedure for all locations.
•
Conferencing Handset-to-Handset and or Handset-to-Audio Panel can also be checked at this
time. Audio Panel-to-Handset operations will be per the particulars on how the AirCell
®
ST 3100
system audio is interfaced to the Audio Panel.

4.7.1.1. Audio Level Adjustments (Revision M and earlier)
Conference Call Audio Level, Side Tone Adjustment, and Mic Bias
1. The ST 3100 audio level adjustments are set by the factory to mid-range and in most
installations will not need to be altered in the field. An audio matrix is provided in the
Transceiver to allow the transmit audio levels from the Audio Panel and handsets to be
received in other handsets or Audio Panel earpiece, at a level similar to the audio level
received from an incoming call. Therefore audio levels can be balanced among the various
handsets and Audio Panel during intercom or conference calls, so that all parties talking are
heard at similar audio levels by all parties. The Handsets are identified by the letters A (HSA),
B (HSB), and C (HSC) in the wiring diagram. On the top of the Transceiver, there is an access
panel to the audio level adjustment potentiometers which are also identified A, B, and C.
Caution: the cover screws are not captive and can be easily lost. Adjust the sum of the audio
from the other Handsets to match the level of an incoming call or to the level desired. To
increase the volume level, turn clockwise. To decrease the volume, turn counterclockwise.
2. Use the additional potentiometers in the top of the Transceiver to adjust the Side Tone
transmit audio level from the Audio Panel (A/P SIDE) and the Conference Call (A/P CONF)
receive audio level to the Audio Panel. These are 14-turn potentiometers and set to mid-range
by the factory.
Note
These adjustments are minor volume adjustments that don’t adjust from a minimum to a
maximum volume level.
