1-1 Front panel
LCD: The large high resolution 5 inch colour TFT display provides all operational information and
spectrum display. The background is black with green graticule and white lettering for critical
information. Menu items are varying shades of blue, the valid indicator is green with the function
indicator in ‘reverse lettering’ yellow. The marker line is white and changes to purple when exactly
positioned over a graticule line. The colours cannot be changed.
Power switch: Press once to latch the switch in, switching on the SDU5600. To switch off the
SDU5600, press the switch a second time, the switch latches outward. When switched on, the LCD
briefly displays the model and firmware numbers.
Tilt bail bar: A tilt bail bar is provided under the front panel (on the bottom case half) so that the
SDU5600 may be tilted upward at the front to improve visibility in certain installations.
Soft function keys: Each one of these three ‘soft keys’ has multiple roles as indicated on the LCD
screen depending on the circumstances in operation.
Special function keys: These three keys positioned to the left of the DIAL are to be used solely for
specific purposes such as to enter a centre frequency, frequency span, display increment and input
sensitivity.
Dial: The DIAL is a rotary control and is used to move the cursor, to make a selection or to move the
marker/centre frequency.
Main keypad: Used to enter numeric information, to control the companion receiver, etc. When a
valid key press is sounded, the SDU5600 will provide a high pitch ‘beep’ (happy), if an invalid key
press is made, a low pitched ‘beep’ (sad) is sounded. The beep can be toggled on/off using the key
sequence FUNC + 6 (BEEP), the default is on.
