4.7 SERVICE

4.7.7 [7. OTHER]

Select [MENU] -> 9.SERVICE -> 7.OTHER. "7.OTHER" includes Submenu-2: "PA,"
"P-BROWSER," "ALARM UNIT," "SOFTWARE ERASE," and DEBUG MODE (for
R&D).
Refer to "Appendix-1" for "P-BROWSER" and information on page 6-47 for
"SOFTWARE ERASE."

1. PA (ON, OFF)

The Submenu-2 "PA" is used to stop transmission operation. This provides a convenient
function for explaining the system operation.
When any change is made to this submenu setting, the changed setting will not be
reflected unless the power supply is turned ON again.
When "PA" is set to "OFF," the FS-xx75 system will not be put into a transmission
ready state even if the PTT key of the handset is pressed. Furthermore, when
transmitting a DSC message, the system will initiate transmitting operation, but not
transmit the message. The same applies to NBDP messages.
Signals controlled by "PA" are TX ON, DRV ON, PA ON, and BK ON.

2. ALARM UNIT (CONNECT, DISCONNECT)

To connect IC-350, set this Submenu-2 "ALARM UNIT" to "ON." Setting "ALARM
UNIT" to "ON" and selecting [MENU] -> 1.TEST -> 1.DAILY TEST will conduct a
test on the "ALARM UNIT".
However, even if "ALARM UNIT" is set to "DISCONNECT," a Distress alert can be
transmitted by pressing the Distress Alert button on the IC-350. A distress alert
reception alarm is also outputted.
