Furuno NX-700B Service Manual page 121

Q21. A new station starts operation. Is it needed to change the program or
circuit to receive messages from this station?
Stations can be edited by addition, deletion and change, etc. in the setting of
"[MENU] -> Service -> Edit Station List."
In addition, Auto mode is performed on the basis of this
data.
Q22. How can the program number be checked?
It is not possible to check the detailed version of the program in "Memory Test" of
"[MENU] ->Service -> Test." Check the detailed version of the program in
"Memory Test" of "[MENU] -> Initialize2 -> Serviceman Test."
Q23. A program cannot be updated.
1) To update a program, use the [RECEIVER] port of the LCD display. Please note
this is not the [RECEIVER] port on the casing of the Display unit on NX-700A.
2) A batch file can be specified via COM 1. When the serial port number of the PC
is specified as other than COM-1, change the setting of the serial port number to
"COM-1" on the PC, or change the setting of the COM port number of the batch
file.
Q24. The icon showing "Battery drain" is displayed.
What problems should occur?
This icon is displayed when the lithium battery voltage of the CPU board on the
Display unit is drained below +2.5 VDC.
When the battery voltage further goes down below +1.8 VDC, it becomes
impossible to back up the memory of received messages. Time for the battery
voltage going down from +2.5 VDC to +1.8 VDC is 1,000 hours at the shortest.
Replace the battery within about one month after this icon is displayed first.
Q25. What is the important information of the Operator's Manual?
The most important information is the configuration and meaning of IDs (station,
message type, "00" message), status display icons on the received message display
screen, selection of local frequency and installation position of the Antenna unit.
For selection of stations, it is necessary to understand the Auto mode. The received
message type is set "Select All" at default. This setting should be changed
depending on the situation.
