The control module switches and buttons are designed to be easily operated while wearing

typical work gloves with a material thickness of up to 3mm. They are also designed to provide

tactile feedback during operation and configured such that the mode of the switch can be

recognized visually or by feel.

The switches and their functions include:

1. Push to Talk (PTT) switch(es) (Momentary-Off)

2. 4-position rotary switch Talk Through (TT) control. The Talk Through circuit can be

3. Battery powered Active Noise Reduction (ANR) Switch (On-Off)

4. ICS Mic live Switch (Live-Mic, Mic-Off) This switch is used to enable continuous active

(latched) PTT mode for Intercom communications.

The boom microphone is serviceable and replaceable in the field. It is a dynamic microphone

which consists of a flexible gooseneck boom and a noise cancelling dynamic microphone

capsule. The Boom Microphone output is specific to the device it is attached to and is achiev-

able by selecting the appropriate cable. Some options may include a pass-through while others

may include a +24dB gain to simulate an electret microphone's output level. If gain is needed,

the power is provided by the input device OR from the control module depending on the specific

input cable. Some options may include a pass-through dynamic 150 ohm, single ended or

differential microphone.

Operation Modes (Power Compatibility)

The power modes listed below are determined by the combination of cables plugged into the

device as well as voltages that are present in different locations or vehicles. Any combination of

power modes based on input connections or signals can be configured within the electronics of

the control module including but not limited to the following scheme.

External Power Source

• Unpowered (0 – 6.0 VDC )

• Battery powered ANR (2-AA batteries)

• Gain switchable Talk Through only

• Selectable Output Level and Frequency Response (Both parameters follow the state

of ANR and/or Talk-Through)

• Boom Microphone Output is specific to device it the is attached to and is configured

inside the input cable. Some options may include a pass through while others may

include a +24dB gain to simulate an electret microphone's output level. If gain is

needed, the power is provided by the input device OR from the control module

depending on the specific input cable.

Low Power (6.1 - 13.5 VDC)

• Battery powered ANR

- ANR Switch position has no effect

• Gain switchable Talk Through
