EMS Sky Connect Series Installation Manual page 59

Description of Problem
MMU display never reaches the "READY"
page
Possible Causes
The initial power on test of the MMU and
hand shaking with the transceiver should
follow the below sequence.
1. The MMU should indicate software
version and MSet version
2. MMU will display a "MMU
Starting"message.
3. After a pause, the MMU should
display the Tracker Transceiver
software and the software in the
LBT. This would be at least V4.7,
and ISO6004.
4. MMU should display "Ready" and
the signal strength.
If you don't see the MMU version the MMU
has failed. If you do not see the transceiver
version, the communication between the
MMU and the transceiver has failed.
Check wiring between the MMU and
Transceiver in the later case.
If you never see the Ready Page, the unit
has not registered on the Iridium network.
Check SIM card activation, antenna and
antenna coax.
