of characters at the receiving station (particularly if a repeater is used). Use CTRL-X and contin-
uous mode if this is a problem.
4. The CWR6850 may be operated in either half or full duplex modes as explained in section 4.7.
However, transmitted text is ONLY "echoed" in the receive section of the display in half duplex.
5. The CWR6850 will only receive correctly if ALL the switches are set correctly. Refer to Chapter
3 for correct starting points for switch selection. The following are general guidelines:
a. CW RECEIVE: CW/RTTY - button out
RX/TAPE - button out
SEND/RECEIVE - RECEIVE or AUTO (CTRL-X Off)
b. RTTY RECEIVE: CW/RTTY - button in
ASCII/BAUDOT - select code (BAUDOT, usually)
LOCK-UOS ON - ON (button in)
NOR/REV - NOR (button out; if LSB used)
BAUD - select rate (45.5, usually)
SHIFT - select shift (170, usually)
TONE - high for VHP; either for HF
RX/TAPE - RX (button out)
SEND/RECEIVE - RECEIVE
FINE - "0" (center detent)
6. Look at the status line. The presence of one or more letters on this line indicates that a feature
has been activated by the corresponding control command. A complete list of the control com-
mands, their action, and the corresponding status indicator is shown in Chapter 7. Often, a
confusing state may have been caused by accidental typing of a control command. Above all,
be careful when using the "CTRL-L:RETURN" key sequence. If invoked, the CWR6850 is expect-
ing to load the HERE IS memories from tape. The ONLY recovery is to load from the tape or
cycle the power on and off! See section 4.3 for further information. The "CTRL-S:RETURN"
tape save command will likewise yield confusing results, but will recover after the total con-
tents of all six HERE IS memories have been transmitted.
7. The RESET button will clear the entire receive display area, clear the printer output buffer, and
clear the tape save buffer. Use this control carefully, but in preference to cycling the power off
and back on.
6.3 Repair Procedures
In the event that your CWR6850 develops a malfunction, the first step is to carefully note all of the
symptoms of the problem. Statements such as "BROKEN" or "DOESN'T WORK" are of little help to
the service technician, and usually lead to longer repair times than might otherwise be required.
Try to provide as much information concerning the failure as you can before you contact your deal-
er. By all means, consult your dealer before calling the factory; he may be able to fix the unit lo-
cally and avoid the shipping and delay times.
The following are some of the things that will concern the dealer or factory:
