1:BackLt - Set the LCD Backlight Intensity
The brightness of the LCD backlight can be adjusted from 10% to 99%. The higher the percentage the
brighter the display.
2:Contrst - Set the LCD Contrast Level
Adjusting the contrast will tune display appearance to compensate for individual display differences.
3:Volts - Show Logic Supply Voltage
For diagnostic purposes, the K45’s main logic supply voltage can be displayed. For proper operation, this
voltage should be 3.3V plus or minus 5%.
4:CW Prac - Practice Launcher
CW Practice can be started from the Configuration Menu #5. This allows Practice to be started when no
keyboard is attached to the K45. Move the cursor to this entry and simply press the encoder. The practice
menu will be displayed, and all options can be set using the encoder. When everything is ready, press the
encoder until the Practice Menu disappears and a practice session will start.
5:Serial # - Set Serial Number
For contesting, the ability to send and keep track of a serial number is indispensable. This command allows
you to preset the serial number to any 5-digit number from 00001 to 99999. Any non-numeric value entered
will be ignored. Once the serial number is set you can increment, decrement, and send the serial number
using buffered commands CTL-G, CTL-D, and CTL-N respectively.
6:ShowRevs - Display Firmware Revisions
For informational purposes all the system firmware revisions are displayed:
CA2 LC W312 PB0 (
Console A2, LCD C, WinKeyer 3.12, PSoC B0)

8:WinKeyer - WinKeyer Mode Launcher
WinKeyer Host Mode can be started from Configuration Menu #5. This allows WK mode to be started when
no keyboard is attached to the K45. Move the cursor to this entry and simply press the encoder. The
WinKeyer menu will be displayed and the K45 can then be connected to a host application on a PC. To exit
WK host mode, press the encoder. The launcher will abort if no host is attached. This prevents a hang
condition if the K45 tries to connect to a host that isn’t connected.
