Plantronics CS70 with GN Netcom SeleCT Switch
Set-Up and Instructions for Use
Although intended for use with a telephone, the Plantronics CS70N provides excellent
accuracy when used in conjunction with the SeleCT Switch and a personal computer
(PC). When used with this switch, the microphone can be toggled back and forth between
telephone and PC, depending upon your needs.
Preliminary Set Up: First you must make the basic connections of the CS70N, SeleCT
switch to your PC and telephone. Although there are alternative methods of making the
connections, and these are described in the literature contained in the CS70N and SeleCT
switch, the following figures show typical arrangements:
Figure 1: Standard Set-Up Figure 2: Computer Only Set-Up
Typical Setup in which CS70N is used for both personal
computer and PC. SeleCT switch is used to toggle
between CS70N output to either telephone or PC.
Simple setup in which CS70N is used only for
PC. SeleCT switch is omitted but audio cable
from SeleCT switch is used to the to make
connection from CS70N to PC (or sound
adapter)
Details:
1. A connection must be made from the receiver on the telephone to the modular
“handset” jack towards the front of the CS70N bottom.

2. A connection must be made from the modular jack toward the back of the CS70N
bottom to the middle jack on the GN Netcom SeleCT switch.
3. A connection must be made from the right jack of the SeleCT switch into the modular
jack on the phone base into which the receiver cord would normally attach.
4. The cord which splits into two 3.5 mm audio plugs is attached to the leftward modular
jack on the SeleCT switch and connects to the personal computer, either directly into
the audio and mic input jacks or (preferably) via an external USB sound adapter.
Note: If you do not intend to use the CS70N with your telephone (and only with your
PC) you can simplify the set-up by simply attaching the bifurcating audio cable that
comes with the SeleCT switch directly from the modular jack on the back of the CS70N
base directly to your PC or sound adapter. In this situation the switch isn’t needed and
nothing will be plugged into the front modular plug on the base of the CS70N (see Figure
2 above)
Note 2: If your telephone has a modular “headset” jack, the connections can be
simplified. In this situation it is not necessary to attach anything to the plug toward the
front of the CS70N bottom (see figure 3 below) and the telephone headset cord is
undisturbed.

“Headset Jack”
Optional set-up for use with telephone having dedicated modular
“headset” jack. In this situation answering and placing calls
involves activating the “headset” button on the phone.
Preparing the CS70N for use with your Telephone and Personal Computer:
1. First you should plug in and charge the CS70N per the Plantronics instructions (it takes
3 hours for a full charge and 20 minutes is the minimum to allow further setup).

2. The “Compatibility” setting of the CS70N may need to be adjusted via the small rotary
dial on the left of the unit. It is preset to position “1” and this tends to work best with
most telephones and PCs. If necessary, you may need to try this in other positions.
3. Connect the CS70N (via the SeleCT switch) to your PC, preferably with the use of a
USB sound adapter
4. Set the sound output volume of the CS70N. This is done with a “crude” and then a
fine method. The crude output is set with the sliding switch on the bottom of the unit
with A being the least output and D the greatest. Selecting “B” is recommended to
start. Fine-tuning the CS70N output is accomplished using the small “+” and “-“
buttons on the back of the CS70N and should be done while running the audio set-up
wizard as described in the next step.
5. Make a preliminary test of the set up with NaturallySpeaking, by opening
NaturallySpeaking and running the Audio Set-up Wizard. (Remember that you need to
“activate” the microphone by pressing the large button on the outside of the ear-worn
unit – this will cause the green light on the base unit to turn on)
6. When using the audio set-up wizard, note the level of the audio adjustment shown in
the graphical display as shown below. The higher the blue bar, the higher the gain
dragon is initiating and the lower the blue bar the less gain or amplification Dragon is
applying. Ideally this bar should come up about ¼ to 1/3 of the way from the bottom.
If the blue bar is extending much higher than this, then you should using the
adjusting buttons on the CS70N to increase the sound output a bit (pressing the “+”
button a time or two). If the blue bar is all the way down at the bottom or not visible, you
should adjust the CS70N output volume down by pressing the “-“ key a few times.
Experiment with this until the blue bar extend up ¼ to 1/3 after doing your sound test.
Using the CS70N:
1. With your PC:
•After dealing with the logistics of physical set-up and adjusting the output
volume of the CS70N as described above, simply move the rocker switch on
the SeleCT switch to the left in order to output the sound to your PC

•Be sure you turn on the microphone by pressing the long button on the
outside of the head-worn unit – this will result in the green light on top of the
CS70N base unit illuminating
•Because the sound coming from the CS70N may be a bit different from sound
originating from standard microphones, we have found that it is best to create
a new user profile on Dragon. After doing so, you will observe outstanding
accuracy when using the CS70N
2. With your telephone:
•In order to answer a call be sure the rocker switch is pushed toward the right
(telephone position), be sure you have turned on the wireless microphone by
pressing the long button on the outside of the wireless unit, and then simply
lift your receiver from the cradle.
•If you have connected by means of a modular “headset” jack on your
telephone (described above), simply activate the “headset” button on your
telephone to answer or place a call.
Good luck. Please call Speech Recognition Solutions with any questions pertaining to
the set-up and use of this system.
