METHOD OF USE

Preparation

When  connecting  with  a  transceiver,  arrange  so  that  the  case  side  of  this  unit  and  that  of  the
transceiver may be at the same potential.

Connect the AF. IN terminal on the rear panel with the external speaker terminal of the transceiver.
Connect from the RF. OUT to the VHF ANT terminal of the television set.
Connect an earphone or a speaker to EXT. SP terminal.

Reception of CW

a. Set the CW/RTTY selector to CW mode. (Switch is off.)

b. Control the sound volume of reception by turning the AF knob on the transceiver.

c. Turn on the POWER switch.

The the cursor is displayed in the upper part of the left side of the screen. At this time, the fol-
lowing message is displayed in the bottom line of the screen: 

<Morse Code>

d. Since the AF input selection of this unit is adjusted to center frequency of 800 Hz, when the re-

ception sound is adjusted to 800 Hz by turning the main dial of the transceiver, RIT or clarifier
control knob, the MONITOR LED flickers in response to the signal.

e. When the first page is filled with 567 characters or more, the text is transferred to the second

page from the first character. Therefore, to look for previous characters, press the PAGE but-
ton. (5 lines are repeated)
When the PAGE button is depressed, the display returns to the first page.

CODE INTERPRETABLE RANGE AND WORD SPACE

Codes generally consists of dots of 1 length unit and dashes of 3 length units. This machine can
distinguish dashes of 2 to 4 length units for dots of 1 length unit. So, a dash shorter than 2 length
units is regarded as a dot, and a corresponding character is displayed.

Example:

·–

·-

1:3

1:1.9

 A

 I

If a dash is longer than 4 length units, its code is interpreted, but since the calculation standard
speed regards it as a slow code, the next code may be interpreted by mistake.

However, since the standard speed is always calculating the average of codes for 8 preceding char-
acters, the interpretation is not disturbed by mixture of one or two characters.

The standard word space is 7 dots. This machine assumes a word space when no code comes
in for two-dot length after a character portion is provided.

This machine displays an underline when an uninterpretable code is fed.

When a consecutive signal longer than 8 bits is fed, the signal is divided by 8 bits each, and
corresponding characters are displayed.
