4 Basics

This section describes the front panel controls, detail of LCD display and introduces the method of
operation employed by the SDU5600 prior to further configurations and monitoring operations. It is
advisable that you read this section carefully before proceeding to explore the full capability of the
SDU5600.

4-1 Control

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.
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.
BACKUP
The SDU5600 is configurable in various ways to the requirements of the operator. All configuration data is
stored into FLASH ROM when the SDU5600 is switch off. However, in the event of failed connection /
communications with the companion receiver, a beep will be sounded and the SDU5600 will revert to the
factory default parameters.
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. Throughout this manual, physical
keys and 'soft keys' are not differentiated when describing key
sequences.
