1.4 Remote Control and Automatic Acknowledge
1.4.1 Remote control
The DSC-60 and a FURUNO SSB radiotelephone communicate with each other by means of
the MIF (FURUNO Radio Interface) protocol, a unique handshaking type signal exchange
system developed by FURUNO. The DSC-60 can also communicate with other makes of
radiotelephones which incorporate data format IEC-61162-1. The remote control feature allows
the DSC-60 to automatically set the DSC and working frequencies and class of emission on a
FURUNO SSB radiotelephone.
1.4.2 Automatic acknowledge
The automatic acknowledge feature, when turned on, automatically transmits the acknowledge
back signal to the sender when an individual, position or polling call is received. With the
automatic acknowledge feature turned on the remote control is also turned on.
Automatic acknowledge is alternately enabled or disabled with the [5/ACK] key.
1.4.3 Both remote control and automatic acknowledge ON
The illustration and table below outline the sequence of events in an individual call when both
remote control and automatic acknowledge are turned on.
