2 SSB RADIOTELEPHONE

Note:
When tuning is initiated in the two-control unit system, the display of the idle control
unit shows “OCCUPIED(ANOTHER CONTROLLER).” In this case, only the
DISTRESS button is operative on the idle control unit. Further, if a control unit is in
use when tuning is attempted at the other control unit, the display of the control unit
which attempted to tune shows “OCCUPIED” plus the name of the equipment in
use: ANOTHER CONTROLLER, NBDP, or DMC.
2.1.4 Using the handset
Hold the handset close to your mouth, press the PTT switch and speak clearly.
2.1.5 Monitoring transceiver output power
During transmission, the IA bar deflects according to the current being fed to the antenna
feeder from the antenna coupler. The unit of readout is amperes. The antenna current
varies with the effective antenna impedance. The swing differs by the frequency and
antenna length. The output power is proportional to the square of an antenna current.
Note:
If IA is not shown, follow the procedure in paragraph 2.1.7 to show it.
