Maximum Loading Speed

. Loading speeds up to 99 wpm are permissable if memory loca-

tions higher than the location being located are empty or contain short messages. If, for exam-
ple, memory location 5 contains about 300 characters and high speed message loading is at-
tempted in locations 0 through 4 a pause between every two dots and/or dashes will occur. To
prevent this either reduce loading speed, erase the long message or load the new message in-
to a higher memory location.

6.

Serial Number Load and Set

. An automatically incremented serial number may be inserted

anywhere in any of the ten messages. It may also be inserted as many times as desired within
a message. The serial number is incremented just as the message is completed.
To insert the automatic serial number during the loading of a message press 

. Insertion of a

serial  number  in  real  time  memory  load  will  halt  the  real  time  loading  of  the  pause.  The  next
keyed character will restart pause loading.
When the power switch is turned on, the serial number is set to 01.
If  the  serial  number  has  incremented,  it  may  be  reset  to  01  in  the  memory  load  mode  by
pressing 

.

The serial number may be changed to any number between 01 and 9999 in the keyer memory
send mode by pressing

 where N N N N is the one to four digit serial number

desired.
Example:  A  starting  serial  number  of  971  is  desired.  Press 

.  The  next  serial

number sent will be 971.

7. Extra  Word  or  Character  Spaces.  In  the  automatic  memory  load  mode,  one  word  space  is

loaded after keying is halted. If desired, additional word (7 space length) or character (3 space
length) may entered. Each time 

 is pressed, an additional word space will be loaded and

each time 

 is pressed an additional character space will be loaded.

Insertion of a word or character space in real time memory loading will stop the real time load of
a pause, the next keyed character will restart pause loading.

8.

Memory Full Warning

. When the memory is completely full, the CW sidetone pitch will de-

crease. At this point, load is automatically terminated. If further loading is desired, it will be nec-
essary to erase one of the other messages.

9.

Semi-Auto  (bug)  Memory  Loading

.  Messages  may  be  entered  in  the  semi-automatic

mode.  During  memory  send,  the  messages  will  be  sent  with  the  selected  dot  and  dash  ratio
and the keyer will revert to automatic operation.
If the paddle has contact bounce, it will be necessary to connect a 1.0 mf cap across the dah
contacts to prevent loading of extra dashes in semi-automatic mode.

IV. Memory Send Operation

1.

Sending a Message

. To start any of the ten messages, switch to Keyer-Memory Send (away

from  the  connector  panel)  and  press  the  digit  of  the  desired  message  location.  The  message
will start when the key pad button is released.
Example: To start message 6, press and release 

.

2.

Interrupting and Restarting a Message

. A message being sent from memory may be in-

terrupted  by  pressing  the  pound  sign  key 

  or  by  tapping  either  of  the  keyer  paddles.  The

Memory keyer then enters normal operation and a hand keyed message may be sent.
The interrupted message may either be restarted at the beginning by pressing the digit of the
message, or resumed from the point of interruption by pressing 

. If the message has com-

pleted, pressing 

 will start the next message, except for message 9.
