Q18. Are alarms outputted with the output contact set to "N.C" or "N.O?"

A18. Factory setting is "Normally Closed." The output contact can also be set to
"Normally Open" with the [J8] jumper of the T-IF board.
An alarm is definitely outputted for Distress alert message. If you want to output
an alarm for alerts in different categories, you should select [MENU] -> 8.
EXTERNAL ALARM.
Q19. Is it possible to turn ON the speaker even with the Handset set to "OFF
HOOK?"
A19. Yes, it is, but you need to select [MENU] -> 7.AUDIO -> 2.OFF HOOK -> "SP
ON." The speaker is kept ON regardless of the Hook setting.
Q20. Is the parameter browser of the FS-2570 system available for use?
Is it possible to make MMSI setting from the parameter browser?
A20. The parameter browser of the FS-xx70 system is not available for use with the
FS-xx75 system.
The parameter browser of the FS-xx75 system can also make and register MMSI
setting when you set the browser to SERVICE MENU -> MMSI SETUP ->
MMSI.

Q21. Is the system provided with the Main Fail (Power Fail) function?

A21. The FS-1575, -2575, and -5075 are all provided with the Main Fail function.
The main fail function circuit is connected between #1 (AC FAIL) and #2 (0V) of
TB7 on the T-IF board. If a short circuit is caused between #1 and #2, the main
fail function will get activated to output a message saying "TX Power reduced.
Ship main failure," automatically reducing TX output power. Therefore, you
should adjust reduced transmission output power to 60W or more to meet
GMDSS requirements.
Note:
The PR-850A AC/DC power supply for the FS-2575 and FS-5075 systems
outputs the Power Fail signal, but the PR-300 AC/DC power supply for the
FS-1575 does not.
Q22. Where to connect a telegraph key?
A22. The telegraph key is to be connected between #11(KEY-H) and #12(KEY-C) of
TB7 on the T-IF board.
To use CW mode, you need to select [MENU] -> 9.SERVICE -> 3.RT SETUP ->
1.SETUP -> CW -> "ENABLE."
Then, the following setting menus are added:
[MENU] -> 7.AUDIO -> 5.SIDE TONE and 6.SIDE TONE LV
