1. FEATURES & PRECAUTIONS
1-1 Features
1. Communications Terminal
As a result of the most up-to-date microprocessor technology, just one piece of equipment can
accomplish complete automatic send/receive of Morse code (CW), Baudot code (RTTY) and AS-
CII code (RTTY & KCS). By using a light pen, it can also handle send/receive of graphic pat-
terns and characters freely.
2. Word Processor Function
Helps with easy generation of documents or letters. With cassette tape recorder storage, the
document can be stored and modified.
3. Selective Calling System
With a eyboard command, SELCAL mode becomes active. Upon receipt of the signal corre-
sponding to your own "SELCAL Characters" (stored in CMOS-Battery-Bac -Up memory), the Θ-
9000E begins to receive the message. And your own "End of Text" will terminate the reception.
Also capable of calling up the specified distant station.
4. Two Display Format and Large Capacity Display Memory

In ASCII, both KCS (Kansas City Standard) and RTTY mode tone sets are available.
13. Battery-Bac -Up Memory
Data in the battery-bac -up memory, covering 256 characters × 7 channels, is retained even
when the external power source is removed. Channel 6 is divided into 16 subsections contain-
ing 32 characters, any of which may be used individually. Messages can be repeated 1–9 times
from a eyboard command and any channel can read out continuously. You can store mes-
sages into any channel while receiving.
14. Anti-Noise Circuit
Well designed anti-noise circuit prevents garbled message in the absence of signal.
15. Screen Display Type-Ahead Buffer Memory
A 3120-character-buffer-memory is displayed on the lower part on the screen. The characters
move to the left erasing one by one as soon as they are transmitted. The operator is free to
prepare messages while another document is received.
16. Function Display System
Each parameter of operation (mode, channel number, speed and so on) is displayed on the
screen.
17. "SEND" Function
Allows to send the transmitted text displayed on the screen, including the data stored in every
channel of the Battery-bac -up memory with an instruction from the eyboard. It is possible to
interrupt the transmission and resume it.
18. Split Screen
With a eyboard command, the same screen format can be divided in two; the upper half for
receive and the lower for transmit, While receiving, you can compose text for transmission in

1-2 Precautions
1. You should plan to read this OPERATOR'S MANUAL thoroughly to become familiar with your Θ-
9000E.
2. Before ma ing connection to a transceiver, practice is recommended with a CRT display.
3. Adjust for minimum SWR between the transceiver and antenna as follows:
OUTPUT SWR
< 10 W Maximum 1.5
10 W ··· 100 W Maximum 1.3
100 W ··· 500 W Maximum 1.1
Table 1 SWR Adjustment
4. Be sure that the connection to the input circuits and output circuits are appropriate. Input sig-
nal and load should be within the range mentioned in the Specifications.
5. Voltage of DC power supply should be within the range of DC 11 V ~ 14 V.
6. DC power supply for the Θ-9000E should not be connected to other equipment if any interac-
tion is noticed.
7. It is suggested that the Θ-9000E is put at a well-ventilated dry place not exposed to the direct
sun with special care for intense heat.
8. Notice the maximum speed as follows:
In full duplex mode, the available speed is up to 9600 baud and in RTTY modem, up to 150
baud. When you connect to the cassette tape recorder in KCS mode, the maximum baud rate
is variable according to its characteristic. In good condition, you can handle up to 1200 baud.
Other modes are usually up o 9600 baud.
9. In order to prevent the possibility of receiver interference from the microprocessor cloc , it is
recommended that the receiving antenna not be adjacent to the Θ-9000E terminal. The trans-
mitting antenna should be well matched and also should not be located adjacent to the termi-
nal to prevent R.F. interference to the logic and video generating circuits of the unit. This ter-
minal is well bypassed and is designed in a metal enclosure to minimize any interference prob-
lem.
New Federal Communications Commission (Part 15) regulations require that the following cau-
tion notice be published:
Warning: This equipment generates, uses and can radiate radio frequency energy and if not
installed and used in accordance with the instructions manual, may cause interference to radio
communications. As temporarily permitted by regulation, it has not been tested for compliance
with the limits for Class A computing devices pursuant to Subpart J of Part 15 of the FCC rules
which are designed to provide reasonable protection against such interference. Operation of
this equipment in a residential area is li ely to cause interference in which case the user at his
own expense will be required to ta e whatever measures may required to correct the interfer-
ence.
