proximity to the BST50 antenna.
The following non-spoken audio feedbacks are given:
Short Bip:
Key press indication on volume, configuration, menu and OK keys.
Short Bip-Bip:
A very short audio feedback to indicate audio decode failure. The MP50 has
detected a transmission from the PNG Base Station, but not been able to receive and
decode fully. Caused by poor radio conditions.
Congestion Biiiip------Biiiiip:
Audio feedback to indicate that uplink communication cannot
be allocated from MP50 to PNG Base Station. This can be caused by poor radio conditions,
or congestion on the radio resources.
Error conditions
The MP50 will conduct an initial inbuilt test and any errors detected will be displayed with an
error code in the display.
If an abnormal condition is detected, an error code will continuously be displayed as E[error
code], where [error code] is a vendor specific number.
A malfunction might be corrected by rebooting the system by switching the MP50 off and
then on again.
If the MP50 becomes unresponsive, a hardware reset can be initiated by holding the power
OFF button for 12 sec.
