CHECK-OUT PROCEDURE

We recommend that you perform the following functions to quickly acquaint yourself with the Con-
tester and to ensure the unit is operating properly.

Keyer Send Mode

1. Turn the power switch on.

2. On the keypad, press and release [

*

][1], then hold your finger on [1]. The monitor tone will in-

crease in frequency.

3. Press [

*

][

*

][1] and hold [1]. The monitor tone will decrease in frequency.

4. Send  a  series  of  letters  with  the  external  paddle  to  "get  a  feel"  for  the  perfect  code  the  CK-2

produces.

5. Press [

*

][2][0][#][7] and send more Morse characters. Note that the length of the dots has short-

ened by one half.

6. Press  [

*

][

*

][2][2][4][#][0]and  send  more  Morse  characters.  Note  that  the  length  of  the  dashes

has increased by four-thirds.

7. Turn the power switch off and back on. The monitor tone will return to 500 Hz and the dot and

dash ratios will return to perfect 1:1 and 3:1 respectively.

8. Press [

*

][

*

][8][0][2] and note that the speed has slowed to 2 WPM.

9. Press the dot paddle and very quickly (before the dot has finished sending) press the dash pad-

dle  and  then  let  up  quickly.  After  the  dot  has  finished  and  a  proper  intracharacter  space  in-
serted, a dash will automatically be sent. This is called

 Dash Memory

.

10. Similar  to  step  9,  press  the  dash  paddle  quickly  and  then  press  the  dot  paddle  momentarily.

After the dash is finished and an intracharacter space is inserted (automatically), the Keyer will
send a dot automatically This is called 

Dot Memory 

or

 automatic dot insertion

.

11. Press [

*

][3] and repeat step 10. Note that the Dot Memory is no longer present.

12. Press [

*

][4] and repeat step 9. Note that the Dash Memory is no longer present.

13. Press [

*

][

*

][3] and then [

*

][

*

][4]. Note that both Dot and Dash Memories are re-enabled.

14. Enter  [

*

][

*

][8]  and  a  two  digit  number  corresponding  to  a  sending  speed  you  feel  comfortable

with. (If less than 10 WPM use 0 as the first digit.) Practice sending at that speed for about a
minute. Because the CK-2 has almost perfect dot and dash ratios and spacing, many operators
feel the speed calibration is low. Actually the CK-2 probably has the best speed calibration on
the market. It is calibrated using the FCC definition of "PARIS" being the standard word. (See
Appendix B.) You might also note that many practice code tapes are actually faster than the ad-
vertised speed.

15. Press  [

*

][

*

][6]  and  note  that  a  tone  will  appear  as  long  as  you  hold  the  dash  paddle.  This  is

called 

Semiautomatic

 or "

Bug

mode

. Turn the unit off and back on and the keyer will return

to fully automatic operation.

16. Press [

*

][

*

][5] and very quickly release the [5] button before the feedback tone stops. The CK-2

should then key continuously until you press any keypad button or touch either paddle. This is
the 

Automatic Tune

 feature. The automatic Tune feature does not operate in the Memory Load

mode. (If you hold the   button down, the CK-2 will not go into the Tune mode.)
