4) Turning the power on while holding the “MODE ▼ ” button will display the current software
version. You must then turn the power off and then on to resume normal operation.
3 Receiver
The transceiver provides both a multi-band sensitive receiver and transmitter. Most of the
controls have to do with the operation of the receiver section. However, Mode, Band, and VFO
apply to the transmitter section as well.
3.1 Communications Mode
The FT-450 transceiver is designed to communicate using Lower Side Band
(LSB), Upper Side Band (USB), Continuous Wave (CW, i.e. Morse code),
Data (DATA), Amplitude Modulation (AM), or Frequency Modulation (FM).
Pressing either the “MODE
▼
” or “MODE
▲
” will step through the available
modes in the forward or reverse direction respectively. These buttons are found to the right of the
“DSP/SEL” knob. Any unwanted modes may be turned off in adaptation using the MENU functions
described later.
Most user’s will not need all of the communication modes shown in Table 2. When you get to the section
on adaptation, you will find that you can configure the system to skip any modes that are not needed.
