As shown in the above figure, the 10 minute intervals are repeated until the message
is acknowledged, the battery runs out, or the MOB device is turned off.
3.6.1 How to acknowledge a DISTRESS RELAY or DISTRESS ALERT
message from the MOB device
MOB device distress messages should be acknowledged within five minutes. Where
the message is not acknowledged within five minutes, the MOB device may enter
sleep mode. In sleep mode, the MOB device cannot receive the ACK signal and the
FM-8900S shows an warning.
Note: The FM-8900S sends the ACK to not only the latest MOB device but can also
send ACK to a maximum of 20 MOB devices.
