PA-44-180, SEMINOLE
The KX 155A also has provision to program 32 channels. Pressing the CHAN
button for 2 or more seconds will cause the unit to enter the channel program
mode. Upon entering the channel program mode,"PG" is displayed next to the
channel number and the channel number will flash indicating that it can be
programmed. The desired channel can be selected by turning the comm kHz
knob. The channel frequency can be entered by pushing the COMM
TRANSFER button which will cause the standby frequency to flash. The
comm frequency knobs are then used to enter the desired frequency. If dashes
(displayed when rotating the outer knob between 136 MHz and 118 MHz) are
entered instead of a frequency, the corresponding channel is skipped in channel
selection mode. Additional channels may be programmed by pressing the
COMM TRANSFER and using the same procedure. To exit the program mode
and save the channel information, momentarily push the CHAN button. This
will cause the unit to return to the previous frequency entry mode. The unit will
also exit the channel program mode if there is no button or knob activity for 20
seconds.
The channel selection mode can then be entered by momentarily pushing
CHAN button. "CH" is displayed next to the last used channel number. The
comm frequency knobs can be used to select the desired channel. The unit will
automatically default to the previous mode if no channel is selected within 2
seconds after entering the channel selection mode.
The unit is placed in the transmit mode by depressing the MIC KEY button.
The unit has a stuck microphone alert feature. If the microphone is keyed
continuously for greater than 33 seconds, the transmitter stops transmitting and
the active Comm frequency flashes to alert the pilot of the stuck microphone
condition.
NAV RECEIVER
The right portion of the display is allocated to NAV receiver information. The
frequency channeling is similar to the COMM when operating in the frequency
mode (Figure 3-1). The NAV increment/decrement knobs are located on the
right hand side of the front panel. The outer knob operates in 1 MHz steps and
increments/decrements the STANDBY frequency display.
