4 Installation and Connection

30

Important:

Fig. 3: Inserting the

circuit board

into the barrel.

Important:

Refer to fig. 3.

Positions, 2, 3, 4: Be sure to place a jumper at one
(but no more than one) of these three positions. If
you place no jumper at any of these positions,
pushing the ON/OFF button will have no effect.

Positions 5, 6: Make sure there is a jumper placed
at one of these positions at all times. With jumpers
at both or none of these positions, the microphone
status on power-up will be undefined.

Never place two jumpers at positions 6 and 2 or 5
and 4 at the same time. This would effectively de-
activate the ON/OFF button.

Do not use any jumper configurations other than
those given in Table 2a. Other configurations may
cause malfunction.

5. Push the circuit board into the shell. To make the cir-

cuit board slide more easily into the shell, turn the cir-
cuit board two or three times completely about its
longitudinal axis as you push the circuit board in.

6. Push the ON/OFF button into the opening in the shell

to the point that the button clicks into place and
tighten the fixing screw.

To prevent the circuit board from getting caught
inside the barrel, make absolutely sure that the
connecting wires (1) will not lie on top of the
jumpers (2). You can double-check on that through
the opening for the ON/OFF key as you push the
circuit board home.
