Spectrum DSP M2 User Manual V1.1
Menu button operation:
In “normal” operation the spectrum display will be visible on the screen and the five “Function”
buttons along the bottom of the display will have the following functions:
• MENU (button F1) – This enters the menu system, allowing the configuration of the
transceiver. Pressing and holding this button will save all settings to EEPROM.
• METER (button F2) – This button selects the mode of bar graph below the S-meter
which is used to display different parameters while transmitting. Repeatedly pressing
this button selects, in turn, the display of SWR, AUD and ALC.
• SPLIT (button F3) – This button toggles “SPLIT” mode on/off. When on (“SPLIT” is
yellow), the transmit and receive frequencies are separated using VFO A and B as
shown on the main frequency display.
• VFO A or VFO B (button F4) – This button toggles whether VFO A or VFO B is the
“primary” VFO. The VFO that is being displayed is ALWAYS the one being used for
receive.
• TUNE (button F5) – This button toggles the TUNE mode on/off. Pressing and holding
this button will disable transmit as indicated by this indicator being displayed in gray.
In MENU mode:
Pressing the MENU button (e.g. button F1) will enter the main menu system by which many
parameters of the transceiver may be configured: These parameters will be discussed in
detail later. Pressing-and-holding this button will save all settings to EEPROM.
Upon entering the MENU mode several of the “soft” buttons along the bottom of the screen
will change their function:
• EXIT/S (button F1) – This exits the menu system, returning to the main display.
Pressing-and-holding this button will save all settings to EEPROM.
• PREV (button F2) – This button goes backwards one screen or six menu items.
Pressing-and-holding this button will jump to the beginning of the menu, or to the end
of the menu if already at the beginning.
• NEXT (button F3) – This button goes forwards one screen or six menu items.
Pressing-and-holding this button will jump to the end of the menu, or to the beginning
of the menu if already at the end.
• DEFLT (button F4) – This button resets the currently-selected item to its default setting.
• PWR (button F5) – shutdown, immediate press Confirm to complete.
Note: If an item has been changed in the menu system that may need to be saved to
EEPROM by long-pressing the EXIT/S button.
