1. FEATURES & PRECAUTIONS
Features:
1. Communications Computer Θ-7000E
Due to the most up-to-date computer technology, one piece of equipment can now handle
both transmitting and receiving in CW, RTTY and SCII.
2. VHF and Composite video output provided:
Both a home TV set and video monitor outputs are provided for display purposes.
3. Printer interface
Centronics para. Compatible interface enables easy connection of a low-cost dot printer for
hard copies.
4. Wide range of transmitting and receiving speeds
10 communication speeds for transmitting (with automatic CW speed adjustment of re-
ceive) and 9 communication speeds for transmitting and receiving in RTTY and SCII. The
multiple speed feature makes the Θ-7000E ideal for mateur, business and commercial use.
5. Built-in demodulator for high performance
Three-step shift (either 170 Hz, 425 Hz, 850 Hz) can be obtained using either High Tone or
Low Tones. Manual adjustment is available by FINE TUNING control.
6. Crystal controlled modulator
transceiver without FSK function can transmit in RTTY mode by utilizing the high stability
crystal-controlled modulator controlled by the computer.
7. Convenient SCII key arrangement
The keyboard layout is the same as a regular typewriter and automatic insertion of LTR/FIG
code makes operation a breeze.
8. Large capacity display memory
The two-page display memory contains 32 characters × 16 lines per page. Page selection
is operated via the keyboard.
9. Split-screen
With a keyboard command, the first page can be divided in two; the upper half for transmit
and the lower half for receive. Sentences can be edited whilst receiving.
10. utomatic Transmit/Receive switch
The transmit/receive switch is controlled by the microprocessor. (Manual operation is also
available.) Built-in remote control key function controls the transmit/receive switch of the
transceiver.
11. nti-noise
new anti-noise circuit prevents garbled messages when there is no signal.
12. Battery backed-up memory
Data in the battery backed-up memory is retained when the external power source is re-
moved. The Θ-7000E has provision for 64 characters × 7 channels in the non-volatile
memory. Data from a memory can be repeated 1–9 times from a keyboard instruction.
Every channel can read out continuously. The channel number in use is displayed in the
buffer.
13. SEND function
The SEND function sends data displayed on the screen, including any channel data after in-
struction from the keyboard. The message can be stopped and restarted.
14. Buffer memory
53-character-buffer-memory is displayed on the 17
th
and 18
th
lines on the screen. The
characters move to the left erasing one by one as soon as they are transmitted. Data in the
channels can be displayed in the buffer.
15. Rub out function
Mistakes can be erased whilst the information is still in the buffer memory. If the mistake
has already been sent a correcting code will be transmitted.
16. Simultaneous access of the memory
Whilst receiving, it is possible to write into the channel memory and the buffer memory
from the keyboard. When sending from the channel memory or the screen it is possible to
