Knobs, Buttons, and Indicators
The front panel of the TW7000 is designed to be easy to use. Knobs,
buttons, and indicators on the display are used to guide operation.
Advanced features are easily accessed from menus.
Power/Volume Knob
The OFF/POWER/VOL control is a rotary knob with power off in
the full counterclockwise position. The speaker volume is increased
by turning the knob in a clockwise direction.
Speaker Button
The speaker can be muted by pressing the SPKR button (located
beneath the SPKR icon on the lower right side of the display). The
status of the speaker (ON or OFF) displays under this icon.
Clarifier Knob
Clarifier offset is achieved by turning the CLAR knob counterclock-
wise for negative offset and clockwise for positive offset (USB mode).
The knob has continuous rotation and provides a maximum of -600 Hz
and +600 Hz offset in 10-Hz steps. This value is shown on the right
side of the display and can be nulled by manually turning the knob
until the offset reads +000 Hz, or by pressing the knob (off). With the
clarifier off, no clarifier information displays. Pressing the knob a sec-
ond time restores the previous offset and refreshes the display.
Keypad
The keypad is used for numeric or alpha character entry. To enter
numeric characters, the desired keypad number is pressed. The dis-
play has a permanent decimal and comma in the frequency field. If a
value is entered that is below 10.000000 MHz, it is necessary to press
the decimal button.
When composing a messages or entering address names, alpha charac-
ters are entered from the keypad using a combination of two keys.
Examples:
Press the top bracketed button and
1 to get character A.
Press the middle bracketed button
and 1 to get character B.
Press the bottom bracketed button
and 1 to get character C.
