Q14. The received time does not display in the receiving list.
ZDA sentence is not inputted. Input the ZDA sentence.
Q15. What does the "Distance" showed on the user display represent?
It is the distance between the own ship position and the position information of a
ship nearest to the own ship included in the received message. This is the distance
information for a user to find whether the message is relevant to the own ship.
This is not the distance between the received station and the own ship.
Q16. Messages cannot be received even in receiving time.
It may be caused due to a failure of the Antenna unit or Receiver unit.
1) Check that power +9 VDC for power supply to the Antenna unit is applied to
the antenna connector. If the power is not applied, the problem is a failure of
the RCV board.
2) Execute "[MENU] -> Service -> Test." If the result of Rx Test is OK, it is
caused due to a failure of the Antenna unit.
3) To know which is faulty, Receiver unit or Antenna unit, replace the Antenna
unit used for a FAX receiver device or MF/HF WR with an FAX-5 antenna
unit. If it becomes possible to receive messages by this, the problem lies with
the Antenna unit.
Q17. Although the icon showing the "During receiving" on 518 kHz is displayed,
a message cannot be received.
If a message can be received on 490 kHz or 4209.5 kHz, it is caused by a failure of
the RCV board. The receiving circuit of the RCV board is comprised of two circuit
systems of 518 kHz and 490 kHz/4209.5 kHz.
Judging from the symptom, it is probably caused by pulling out of synchronism
due to incorrect adjustments of FSK detection on 518 kHz.
Q18. Although the received signal intensity seems to be strong enough,
a message cannot be received.
It is probably caused by the same reason as described in Q17. Even if the signal
intensity is strong enough, if synchronization is not achieved properly, reception is
stopped when the error rate exceeds 33 %. The signal receiving status can be
monitored by the setting of "[MENU] -> Service -> Rcv Monitor".
Q19. A received message cannot be printed.
Check the setting of "[MENU] -> System -> Printer." Select "NX-700A" for the
type NX-700A. In case of type NX-700B, configure the setting according to the
specification of the printer.
Q20. The icon
in the Status field of NX-700B (not incorporating a printer).
Execute "Cancel" of the printer on the [PRINT] menu.
Then, select OFF in "[MENU] -> System -> Printer."
