The 7000 microphones should be wiped with a dry cloth. Excess moisture may
damage the microphones.
Solvents and abrasives will cause permanent damage to the 7000.
1.7.2 Care & Maintenance of your M1950E Coupler Microphone
Microphones are perhaps the most delicate of FONIX products. They require
care and concern when handled. At the risk of sounding negative, the following
is a list of the five microphone DON’Ts.
1. Don’t bend the microphone cord at the connection of the cord and the body!
This is perhaps the most common cause of microphone damage. The place
where the cord and the body of the microphone meet is the most fragile part
of their connection. The less strain you put on this area, the longer your
microphone will last.
2. Don’t hit the microphone against the sound chamber or any other object!
The microphone head is delicate and easily damaged. Hitting the micro-
phone against anything will do you no good and the microphone much
harm. Similarly, be careful not the drop the microphone on the floor.
3. Don’t pull the microphone from the coupler by the cord!
When removing the microphone from the coupler, grip the microphone
body, not the cord. Pulling on the cord damages the connection.
4. Don’t get Fun-Tak on the grill of the microphone!
Fun-tak that accumulates on the grill will fall into the microphone body and
onto the diaphragm which will damage the microphone.
5. Don’t touch the diaphragm of the microphone!
The diaphragm is located inside the grill of the microphone and is extremely
sensitive. If you need to take the grill off the microphone, please do so with
extreme care, and be especially careful not to touch the diaphragm, as this
will cause damage!
Overall, just be aware that your coupler microphone is a delicate instrument
that needs to be treated with care and respect. If you do so, the two of you will
be rewarded with a long, happy relationship.
1.7.3 Locating the serial number and software version
When contacting the factory, it is very useful if you have your serial number
and software version handy. This information will help us help you regarding
repair, upgrade, and technical questions.
The serial number of your 7000 test system can be found on the back of the
main module, just to the right of the power switch. See Figure 1.7.3A.
