The operation is similar to that of many other keyers. In particular, it is (deliberately) designed similar to the K3NG keyer, since its operation has proved to be advantageous in practical operation. Note in advance: if you have the keyer "zerkonfiguriert" (col. german for "kaput"), so you can turn it on with the CMD button pressed to reset it. As a general rule, if the input is successful, a high-pitch beep will be output.
The "Command" mode is accessed by pressing the CMD button once. The keyer acknowledges this with a short tone sequence low, medium, high (something like a "video game sound"). If the keyer is in Command mode, the yellow CMD LED lights up. Now the following commands can be entered via a connected paddle:
- "E" ... plays the current speed in WPM. For example, if 15 WPM are set, ".---- ....." will be output.
- "A" ... changes to Iambic mode A. For confirmation, the keyer responds with a high beep.
- "B" ... changes to Iambic mode B. For confirmation, the keyer responds with a high beep.
- "D" ... changes to Ultimatic mode. For confirmation, the keyer responds with a high beep.
- "T" ... changes to sideswiper mode. To exit, press the CMD button.
Attention, well-known bug : The key buffer will not be cleared on exit, which may have unexpected side effects...
- "M" ... switches the dot / bar memory on or off. For confirmation, the keyer responds with a high beep.
- "F" ... change the sidetone frequency. With the dot side of the paddle the sound becomes higher, with the stick side of the paddle the sound gets deeper. To exit, press the CMD button again. After that, the keyer is back in command mode.
- "I" ... switches the TX line on or off ("TX inhibit"). For confirmation, the keyer responds with a high beep.
- "O" ... switches the sidetone on or off. For confirmation, the keyer responds with a high beep.
- "N" ... changes the polarity of the paddle. Normal and reverse. A point becomes a dash and vice versa. For confirmation, the keyer responds with a high beep.
- "W" ... change the speed setting. With the dot-side of the paddle pressed it slowly becomes faster, with the dash-side it gets slower. To exit, press the CMD button again. The keyer outputs the chosen speed for confirmation. After that, the keyer is back in command mode.
- "P" ... memory programming mode. See below for more ...
- "X" ... If you can not find the CMD button, HI HI, you can also leave the command mode with this command. The keyer acknowledges this with a short tone sequence high, medium, low ("video game sound the other way around ...")
If you enter a command unknown to the keyer, a low acknowledgment tone will be output to flag for the errornous input.
In Command mode, you still have the option of triggering the following actions by pressing the Memory buttons and immediately leaving Command mode. This can greatly speed up usage:
- Button-MEM1: selects 10 WPM and exits Command Mode.
- Button-MEM2: selects 15 WPM and exits Command mode.
- Button-MEM3: selects 20 WPM and exits Command mode.
- Button-MEM4: selects 25 WPM and exits Command mode.
- Button-MEM5: selects ratio 1: 3.00 ("normal" ratio)
- Button-MEM6: selects ratio 1: 3.25 ("slightly" extended ratio)
- Button-MEM7: selects ratio 1: 3.50 ("strongly" extended ratio)
- Button-MEM8: turns on auto ratio weight, or off.
Attention, well-known bug : this will not leave CMD-mode(!).
The command mode can be left, either by entering an "X" (see list above) via the paddle, or by pressing the CMD button, or by pressing a memory button. If you select the latter option, the additional function of the button is executed before the command mode is ended.
The memory texts 1-8 are programmed as follows:
- Press CMD button to enter command mode. The keyer acknowledges this with low-mid-high.
- Enter "P" over the paddle. The keyer acknowledges this with a high beep.
- Enter a digit from 1-8 over the paddle, depending on which button should be re-allocated. A successful entry is acknowledged by the keyer with a high beep. If you want to cancel, you enter something else. The keyer acknowledges this with an error tone and returns to command mode.
- Now the desired text is entered via the paddle.
- To end the input, press the CMD button. The keyer acknowledges with a high beep. Then you are back in Command mode and can make further settings or program other memory texts.
Note: If an entered memory text is too long, the keyer saves the previously entered text and ends the input with a low Feherl tone.
The keyer is equipped with an energy-saving function. If the power LED lights up, the operating state is "wide-awake". If the power LED flashes, the keyer "dozes". If the power LED goes off, the keyer sleeps. The keyer needs less than 100μs to go from sleeping to waking. In sleep mode, the keyer can therefore wake up every paddle movement (dot or dash) almost instantly. If you feel disturbed by the flashing, you can set the internal jumper for the power LED differently. This always lights up.
