Switching DZM side tone on or off:
From the ’Audio Setup’ sub-menu, use the arrow keys to navigate
to 'DZM Side tone'.
Press the
ENTER key to select. The 'DZM Side tone' screen
displays.
Use the arrow keys to navigate to the DZM side tone option
required (e.g. 'On' or 'Off').
Press the
ENTER key to select and save.
The DZM side tone is switched 'On' by default. This may cause
excessive noise in some systems, so if side tone is provided by the
aircraft ICS during calls, DZM side tone should be switched to 'Off'.
Switching GPS/SMS confirm tones on and off
DZM GPS/SMS tones may be switched on or off as required. GPS/SMS tones are sounds that are emitted when an
alert condition is raised by the DZM’s tracking system:
When there is no GPS lock when the aircraft takes off.
When the DZM cannot send position reports after several retries due to low signal strength.
When the DZM has a full message queue (usually due to low signal or the sat phone not present in the
cradle) and the oldest message has been deleted to make room for a newly created position report.
Switching GPS/SMS confirm tones on and off:
From the ’Audio Setup’ sub-menu, use the arrow keys to navigate
to 'GPS/SMS Tones'.
Press the
ENTER key to select. The 'GPS/SMS Tones' screen
displays.
Using the arrow keys, navigate to the keypad mode required (e.g.
'On').
Press the
ENTER key to save.
