Keyboard Commands
K45 operation is controlled by ESC and/or Control commands. ESC commands are used to start
configuration menus while control commands result in an immediate action.
ESC Commands
The user first presses the ESC key, releases it, and then presses the desired command. ESC will be
displayed on the status line to let the user know that the K45 is waiting for a command entry.
ESC C – Configuration Mode
System configuration is divided into fine menus, each with eight setting options. The user navigates the
menus using the left/right and up/down arrows. Moving extreme right or left will move to the next or previous
menu, wrapping from first to last and last to first. An underline cursor indicates the selected item. The
ENTER key opens that item up for editing and a submenu will show the current setting. The setting can be
changed with the right/left arrows or by entering a new value on the keyboard.
Each menu item leads off with a number.
1:Tx WPM
for example. In this case, entering the number 1 will
directly open the TX WPM entry. When finished with an entry, press either the enter key to save the new
value or ESC to abort leaving the setting as it was. Values are stored in on board EEPROM so that they are
preserved if you happen to disconnect power and are automatically restored on power up.
When the K45 is used without a keyboard, the rotary encoder is used to access configuration by pressing
and holding the encoder button down until the menu appears.
Please note that:
1) A quick encoder press and release will bring up the message launcher menu which can be
cancelled by re-pressing and holding the encoder button.
2) If the encoder is held after the configuration menu appears, K45 will go into low power sleep.
Once the configuration menu is up, the user can scroll through the various entries by turning the encoder.
Press the encoder quickly to open an entry for editing. Turning the encoder will modify the entry. When
finished, press the encoder to save the change return to the main menu. To leave the main menu and return
to operational mode, press and hold the encoder button until the menu clears.
Configuration does not interrupt CWR input, all incoming text will continue to be added to the Rx display
window in the background.
A full list and description of all the configuration menus is presented in Appendix A starting on Page 23.
