4. The radio automatically switches to channel 70 to transmit the call request then automatically switches to channel 16, the designated response channel for all-ships calling. Making an automatic distress call If you have programmed your MMSI number, your radio can transmit an automated distress call with your current location and nature of the distress. The radio then monitors channel 16 for a response and repeats the distress call every few minutes until it receives an acknowledgement. To send an automatic distress call, press and hold DISTRESS for three seconds. If no MMSI number has been programmed, the radio prompts you to enter your MMSI number. If you want to include the nature of your distress in the distress call, use the following distress procedure: 1. Press DISTRESS. 2. The radio displays the list of distress conditions; use Channel Up and Channel Down to choose the nature of your distress, then press and hold DISTRESS for three seconds.

Receiving a DSC call If your radio receives an individual DSC call from another station, it sounds an incoming call tone and displays the name/MMSI number of the station calling you. To respond to the call, select Send: Able-Comply; the radio sends an acknowledgement and automatically switches to the designated response channel. To reject the call, select Send: Unable-Comply; the radio advises the other station that you are unable to respond to the call. If the DSC request contains a response channel that you are not allowed to use, the radio displays Not Support CH; your only response option is Send: Unable-Comply. If the radio receives a group or all ships call, it sounds an incoming call tone and automatically switches to the designated response channel. Receive log Just like your telephone's caller ID list, your radio keeps track of the calls you receive. The receive log is useful if you have been off your boat or away from your radio and want to see who has tried to contact you. The radio displays the last 10 distress calls and the last 50 non-distress calls that it received. If you have unread incoming DSC calls, the radio displays a Message icon. When you display all Distress and Other receiving logs, the message icon disappears. Uniden MHS235 Radio Owner's Manual E-23
