CHAPTER 2
SIMPLE HOOK-UP AND OPERATION
Although there are many features of the CWR6850 explained in this manual, you may wish to first
"plug-it-in" and "try-it-out" without reading the whole book. This section of the manual presents
enough information to start using the CWR6850, but you will eventually need to read Chapters 3,
4 and 5 to take full advantage of the many conveniences included in your CWR6850.
2.1 Connections to the CWR6850
Refer to Figure 2 and notice the various connections you may make to and from the CWR6850. For
a start, it is recommended that you make the following connections at the present and leave the
other connections until after you have read Chapters 3, 4 and 5.
1. Connect a good ground wire (1/4" shield braid preferred) between the CWR6850 cabi-
net, transceiver cabinet and all other station equipment cabinets.
2. Connect a shielded audio cable between the receiver speaker (audio) output and the
CWR6850 AF IN - RX connector.
3. Connect a shielded audio cable between the transmitter microphone audio input and
the CWR6850 AFSK OUT - TX connector. Check your transmitter manual – some trans-
mitters have +12 VDC on the mike input lead to run remote controls; use a 1 µF block-
ing capacitor at the mike connector to prevent damage to such a transmitter.
4. Connect a shielded audio cable between the transmitter push-to-talk input and the
CWR6850 SW.OUT - REMOTE connector. (Steps 3 and 4 may be combined in a 2 con-
ductor "stereo" cable with the transmitter end connected to a microphone connector;
these steps are only necessary if you intend to transmit during these preliminary tests.)
5. Connect the keyboard to the CWR6850.
6. Connect the CWR6850 DC power cord to a source of well-filtered DC voltage between
12.0 and 14.5 Volts. The CWR6850 draws approximately 1.6 Amperes; the battery or
DC supply should be capable of supplying this current CONTINUOUSLY.
*** CAUTION ***
Be sure that you connect the RED wire to the POSITIVE terminal and the BLACK wire to the NEGA-
TIVE terminal of the power source. Serious damage may be caused to both the CWR6850 and the
power supply if the proper polarity is not observed! Do not turn on the power at this time.
