Frequency readout:  

 

 Click and then release the <

Fn

>

 

switch will activate the frequency readout.  

 
The default mode of readout is both a numerical readout, sequenced one digit at a time on the LED display, and 
annunciated in Morse by the side tone. The 100 kHz, 10 kHz, 1 kHz and 100 Hz digits are indicated, in that order.  
MHz digits are implied by the band in which the rig is currently operating on. A dash [ - ] on the display and an 
“R” in Morse indicates the decimal point separating the 1 kHz digit from the 100 Hz digit. Zero's are sent as the 
cut number “T” in Morse. Therefore, a frequency such as 7.0400 will be sent as T4TRT in Morse and seen  as 040-0 
on the display. It is possible to set the rig to indicate the frequency only with the LED display.  

S: Selecting Keyer code speed 

“S” on the display 

Keyer speed has a range of about 10 to 35 wpm. Initial power on speed is set to 20 wpm. Code speeds are selected 
in approximatively 1 wpm increment using the paddle.  

 

Click and hold closed the 

Fn 

switch until the letter “S” is annunciated and appears on the 7 segment 

display, then release the switch.  

 

This mode will automatically exit after 1 second if no action has taken place in that time.  

 

Increase speed: Close DAH paddle or Tune up button .   

 

Decrease speed: Close the DIT paddle or tune down button.   

 
NOTE:

 If the rig is in Straight key mode, the Tune up and Tune down switches can used to change code speed. This 

allows changing the code speed used to send previously stored messages.   
 

Saving the selected code speed to memory: 

 
If you would like to save the current code speed to memory so that it will be loaded on power up as the default 
speed, this can be done in the “user preferences” function.  

M:  Keyer Memory entry:  

“n” on the display – the closest we can get to “m” with 7 segments  

There are three keyer memories available. Each message location an store up to 63 characters, which includes word 
spaces.  
 
Upon releasing the <

Fn

>

 

switch after the letter “M” has been annunciated, the receiver will mute and entry of the 

message via the paddle may begin.  
 

 

If keyer memory entry has been selected by mistake, clicking the <

Fn

> switch will exit this mode without 

disturbing the contents of the memory, provided the paddle has not yet been used.  

 
Timing for determining letter and word spaces is automatic and is based on “ideal” timing. Since many of us have 
a hard time sending with ideal letter and word space timing, generally running letter groups and words together, 
segments on the LED will flash to let you know when a letter time out or word space time out has occurred. The 
upper left LED segment (f) will flash at the letter space interval and the upper right segment (b) will flash at 
the word space time out. Paying attention to the flashing lights will allow you to enter a message without timing 
mistakes.  

Checking and storing the message: 

 

 

When you have finished keying in the messages, click the <

Fn

> switch.  

 

The message will then play back so you can check that they were entered correctly.   

 

If the playback is good and there are no mistakes,  

 

Click  <

Tune down

>, <

Tune up

> or <

Fn

>, to store the message in one of those three locations. A Morse 

“R” will acknowledge the switch press. It then takes a second or so to store the message and once 
done, the side tone will beep once and the rig will return to normal operation.  

 

Click <

Km

> if you the message had mistakes and you want to re-enter it. “EM” (Enter Message) will be 

annunciated by the side tone.  

 

If you want to enter and store another message, the memory mode must be again selected using the 

Fn

 

switch, as once a message is stored, the rig goes back to normal operation.   

Sending messages:

  

 

First, click the <

Km

> button, then within 1/2 second, click either the 

<Tune Down>, <Tune Up> or <Fn>

 

switch to transmit the desired message.   

 

Message 1 

is sent by clicking the

 <Tune Down> 

switch within 1/2 of a second after releasing the Split

 

switch.
