LOCAL HEADSET CONNECTION
Insert the headset/microphone into the 4 pin
XLR connector on the front panel. See the mi-
crophone connection diagram (Figure 2) if
other than a Telex Headset is used.
HEADSET MICROPHONE SELECT
SWITCH
If the headset you are using has an Electret mi-
crophone, the local microphone select switch
must be in the “ELT” position (Electret). This
switch is located on the rear panel. A +5 volt
bias is available at the microphone plug for
electret use.
If you are using a headset with a dynamic mi-
crophone, place the local microphone select
switch in the “DYN” position (Dynamic).
NOTE:
FOR PROPER OPERATION YOU
MUST MATCH THE TYPE OF
MICRO-
PHONE YOU ARE USING WITH THE DY-
NAMIC/ELECTRET SWITCH
LOCATED
ON THE REAR OF THE UNIT.
TRANSMIT SWITCH
Allows the operator to select three different
types of transmitting modes; continuous trans-
mitter, transmitter off, or remote transmitter.
For most operations, place the transmitter
switch in the “CONT” position (Continuous
mode).
In the
Continuous
mode the transmitter
therefore
will be on at all times regardless of
whether the portables are on or not.
In the
Remote
mode, the only time the
base
can transmit is when a portable unit is turned
on.
In the
Off
mode the BTR-200 base station
will not transmit to the remote belt-packs.
This mode might be used if the base is to be
a monitor station only.
