The counter has a high speed and low speed announcement mode. The high speed is the default mode.
After a short time of using this device, copying speed of numbers improves dramatically. It makes a
great cw "numbers" trainer!

Keyer Instructions

Operation:
General notes on using the dit, dah and mem switch to control the keyer: The switch on pin 4 of the
keyer chip will be referred to as the mem switch. Multiple functions result from multiple switch-press
combinations (mem alone, mem+dit, mem+dah, mem+both dit and dah). Also, the switches can be
pressed and released (PAR) OR pressed and held for two seconds (PAH). This doubles the number of
combinations of the three control switches.
Generally, PAR is used for actions: send the code speed or send a memory. PAH is used for settings:
change the code speed (no pot) or record a memory or change the iambic mode.
4 menus are used for setting various options - they are activated by a PAH of the mem switch alone or
plus a simulpress of dit or dah or both. The menu selections are made by pressing either the dit or dah
switches - you will then normally hear a corresponding dit or dah via the sidetone, the selection will be
made and you are then returned back to normal keyer mode. In general, the operator can skip a menu
item by a PAR of the mem switch.
Note that the keyer sidetone will be lower in pitch (about 270 Hz) for keyer commands such as the menu
prompts. The normal sidetone pitch for routine sending defaults higher at about 580 Hz and can be
changed with the SS menu command.

Powerup:
After powerup the keyer will send an FB through the sidetone to signal correct operation. If either the
dit or dah input is pressed during powerup the opposite paddle input will act as a straight key. An easy
way to do this is to plug in a mono plug from the external key or keyer cable into the stereo paddle jack
of the NC2030. The ring contact of the paddle jack will then be grounded.
Speed Readout:
The speed (in WPM) will be played through the sidetone if the mem switch is simulpressed with the dit
switch and then both are released. I normally press the mem switch first and hold it, press the dit switch
and finally release both.
