System Controls

6.1

Display Brightness

The display brightness may be set to one of 5 levels, 0 through 4. F-press the
"METER/DIM III" button to step through these levels. The current level shows
on the lower right of the display (unless it is 0, in which case the display is
blank). Rotating the "DSP/SEL" knob will then change the level. Press the
"METER/DIM III" button to save the new value and resume operation.
Warning: It is recommended that the display remain at full (4) brightness. People have reported a hum on
the transmitted audio when the value is set lower.
6.2

Semi-automatic Keyer

The FT-450 contains a semi-automatic keyer for CW transmission. It has the advantage (and to some,
disadvantage) of making the code stream more uniform. The relative size of dots, dashes and spaces a
standard size for a given code speed. Press the "KEYER" button to toggle the keyer on or off. Input to the
keyer can be adapted for either a straight key or paddles. See adaptation for parameters associated with
CW.
6.3

Custom Switch

The manual says that the C.S button will act as a shortcut to one of 52 functions. However, there are only
20 unique functions that are not duplicates of either press, f-press, or t-press of existing buttons or knobs.
The unique functions are shown in Table 9.
