1.4Remote Control and Automatic Acknowledge

1.4.1Remote 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.

1.4.2Automatic 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.

1.4.3Both 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.
