Common questions about manuals, registration, and support for this brand.
To reset, power off the unit. Hold the command button down and then power on the unit. Push and release the reset button (located internally or on the rear panel, depending on the model), then release the command button. This restores factory defaults.
The Mini-Yack keyers typically require 2 AA batteries. Ensure the internal battery jumper is set to the ON position if the unit was shipped to you or has been in long-term storage.
Yes. Plug your straight key into the KEY jack using a 3.5mm mono or stereo plug. For a stereo plug, hold the key down during power-up or configure the ring and shield wires to detect straight key mode. The unit will send 'STK' upon confirmation.
You can change the speed by pressing and holding the COMMAND button while operating the DIT and DAH paddles. DIT reduces speed, while DAH increases it. The keyer will play an alternating sequence of dit and dah while changing speed without keying the transmitter.
