2.5 Menu Settings
2.5.1 Functions - This section describes operation of the front panel controls. There are three operator
switches, the LCD display and alarm indicator LEDs. All functions for the equipment are controlled by these
components. The functions are (see Figure 2.4):
Power Up
Normal Display
Menu 1
Frequency Translation Mode (95 > 140 MHz or 140 > 95 MHz)
Menu 2
140 MHz end center frequency (110 to 170 MHz in 1 MHz steps)
Menu 3
Input Level in dBm (-20 to -10)
Menu 4
Attenuation in dB (0 to 10)
Menu 5 Mute
Menu 6

Menu 7

Save Menu
When go to end
Alarm indications appear on the LEDs (see figure 2.2).
All program changes must start with the operation of the Menu/Execute switch and must also end with the
operation of the Menu/Execute switch verified by the “Save Settings?” Menu. If this sequence is not
followed, none of the changes will take effect. If programming is initiated and no operator action takes
place for approximately 30 seconds (before the final press of the Menu/Execute switch) the display will revert
to its previous status and you will need to start over.
2.5.2. Power On Settings
NOTE: The last status of a unit is retained even when power is removed. When power is restored, the unit
will return to it's previous settings.
When power is first applied, the LCD display goes through three steps.
1. The LCD goes black to show all segments are functioning.
2. The software version will be displayed.
REV 1.52

The unit is now operational and ready for any changes the operator may desire.
