You have an easy2-MOB and it is not receiving the DSC-Acknowlege from the DSC VHF radio?
The reason might be the automatic acknowlege of the DSC VHF radio.
The DSC VHF radio (e.g. Raymarine or B&G) is transmitting the Acknowledge directly after reception and within that time, the easy2-MOB is still busy.
Note:
Also change the AUTO ACK to MANUAL for DSC TEST Calls.
Actions:
Manually transmitt again the DSC call afterwards.
This has no influece within an emergency case. This closed and open Loop call will not be acknowledged automatically!
Your easy2-MOB is absolutely ok and ready for use.
Within the easy2-MOB unit you can programm up to eight MMSI numbers.
Just download the easy2-MOB app for your mobilephone:
Android:
easy2-MOB
iOs:
easy2-MOB
Activate Bluetooth on your easy2-MOB unit:
1. Push the yellow magnet switch to the left to “ARMED” if not done yet.
2. Press TEST button as long until the white LED stays on
3. Open the App you downloaded before, activate Bluetooth on request
4. Follow instructions within the app to programm the MMSI numbers
5. If you see an MMSI number with 211002010 this is our trial number, you can delete this one
Note:
If you don´t programm any MMSI number into your device, the unit will go into Open Loop directly after actviation in an Emergency case.
Check that the magnet switch is set to “ARMED”.
After that all buttons are active.

Also when you put the unit inside your life vest, get sure that you ARM the unit.
Only then it can activate in an emergency case.
Reason:
New regulations for AIS DSC MOB devices require a deactivation functionality.
This is done with the magnet switch on the easy2-MOB device.
