ESC K - Key mapping Menu
The mapping of K45 keyboard keys to Morse characters can be customized. This feature is primarily used to
support international character sets.

Figure 4 – Key Mapping Menu
As shown in figure 4, there are three data entry points:
1) The character you wish to edit.
2) The character you wish to map it to.
3) Optional

letter of a prosign.
When the menu is first shown, the cursor will be at position 1. Enter the key to map here. When a key is
entered, the Morse letter it currently maps to is shown at position 2. To change the mapping, use the right
arrow key to move the cursor to position 2 and enter a new letter. Position 3 is optional, sometimes the
target Morse letter can only be represented as a combination of two existing letters, this is commonly known
as a prosign. To create a prosign, simply enter the letter pair at positions 2 and 3. Otherwise just enter a
space in position 3. To continue with a new mapping move the cursor back to position 1 and enter a new key
to map. When finished, ENTER will save the mapping(s) to EEPROM or ESC will cancel the mapping and
revert to the pre-existing mappings. Following the above example, after saving the mapping, the prosign KN
(dah-di-dah-dah-dit) will be sent when the ( key is pressed.
The K45 follows International Morse convention and defines punctuation as shown in the following prosign
table. These are predefined by default in the key mapping table. Any of these can be changed simply by
remapping them as described above.

Table 1 – Punctuation to Prosigns Defaults
Several keys are fixed to Q codes, it is not possible to re map these keys:
Shift-[ is mapped to QRZ
{ is mapped to QRV
Shift-] is mapped to QSL
} is mapped to QSY
ESC-L - Clear both display windows
The contents of the receive buffer and transmit buffer will be cleared when this command is entered.
ESC-M - Message Launcher Menu
Since the F1 to F12 message keys are not very descriptive, it's easy to forget which key a message is linked
to. Message Launcher provides immediate hints for all the message keys in one easy to access menu.
When a message is loaded, an eight-letter hint (tag), is entered for each message. Message Launcher
formats the message keys and tags together to remind you where the messages are and then allows you to
quickly launch a message of choice by entering a single numeric keystroke.
