determine the presence of signals below the squelch threshold be-
fore transmitting. The Monitor switch is either momentary or lock-
ing; and the switch can be wired either to ground or to unground
the squelch circuit. The Transmit switch bar can be depressed only
while the Monitor bar is depressed, thus requiring the operator to
verify that the channel is idle before transmitting. The Transmit
switch is momentary only and cannot be locked. The Transmit/
Monitor Switch Kit is Shure Model RK199S. General microphone
wiring instructions are supplied with the kit, but specific transceiver
wiring details must be obtained from the transceiver schematic
and/or the manufacturer of the unit.

TYPICAL FREQUENCY RESPONSE
FIGURE 2
Polar Pattern
Cardioid (unidirectional) - uniform with frequency, symmetrical
about axis (see Figure 3)

Impedance
Dual. Microphone rating impedance is 150 ohms (260 ohms ac-
tual) for connection to microphone inputs rated at 19 to 300
ohms and "High" for connection to high-impedance microphone
inputs. Switch is in high-impedance position as supplied. To
change impedance, see sections on lmpedance Selection and
Connections.
