General Description

Dual microphone configuration features
The M-100 features two built-in microphone elements, one dynamic and one condenser. The unique output signals may be individually crafted and then blended to produce a single rich voice signal. The condenser microphone responds to a broad frequency range including the distinctive crisp highs, while the dynamic microphone adds depth and warmth, providing the emotional subtext desirable for a genial “ragchew”. By combining the two different microphone elements in this manner, favorable sound quality can be created for any operating style.
Treble boost cowling produces a unique tonal texture
The simple clip-on cowling enhances the high-frequency response of both microphone elements and can minimize the aural interference from either side. The cowling serves to concentrate the voice input with a peak at around 1 – 1.5 kHz, producing a unique tonal texture.
Air cylinder magnetic contactless PTT key
The PTT key with contactless triple air cylinder magnetic construction delivers smooth fingertip-sensitive operation over an extended stroke distance.
The key has been designed with optimal balance between key weight and stroke to provide the perfect tactile response. Meanwhile, the contactless switch provides years of fault-free operation with minimal mechanical degradation.
The PTT key features a built-in one-click lock function.
Convenient High-Cut filter and Low-Cut filter key buttons are at your fingertips.

The unit may fall or tip over, resulting in injury.
| Do not place objects containing water, such as vases, cosmetics or cups, on top of the unit.
The water may spill and get inside the unit, resulting in fire or malfunction.
| Do not place the unit in humid or dusty places.
Doing so could cause fire or malfunction.
| Do not wipe the case with thinner or benzene.
Use a soft, dry cloth to wipe dirt off the case.
| Do not drop the unit or subject it to strong shocks.
Doing so could cause injury or malfunction.
| Disconnect the power supply cable and all cables connecting the unit to the radio before moving the microphone.
| Do not place the unit in places exposed to direct sunlight or near heating appliances.
Doing so could cause deformation, discoloration, etc.
| Store in a place out of the reach of small children.
Failure to do so could result in injury, etc.
****| Do not use products other than those specified by Yaesu.
Doing so may result in malfunction.

****Special Precautions in using the M-100

• To reduce extraneous noise, place the microphone as far away as possible from power supply equipment and power supply cables.
• To avoid adverse effects of transmitted RF radio waves, install the microphone as far away as possible from the transmitter antenna and antenna cable.

Controls & Connections

1. key (Condenser Mic Element key)
Switches to the condenser microphone ([C] LED lights up orange).
When the [C] and [D] keys are pressed, the audio output signals of the condenser and dynamic microphone elements are combined.
2. key (Dynamic Mic Element key)
Switches to the dynamic microphone ([D] LED lights up orange).
When the [C] and [D] keys are pressed, the audio output signals of the condenser and dynamic microphone elements are combined.
****If neither the [C] key nor the [D] key is pressed, the microphone output is turned off. The [C] and [D] LED’s blink simultaneously.

3. LC (Low-Cut) key
When this key is pressed, a low-cut filter (cut-off frequency 340 Hz, -6 dB/octave) is activated ([LC] LED lights up blue).
4. HC (High-Cut) key
When this key is pressed, a high-cut filter (cut-off frequency 2 kHz, -6 dB/octave) is activated ([HC] LED lights up blue).
When the [LC] and [HC] keys are pressed, both filters operate simultaneously.
While listening to the transmitted audio using the transceiver monitor function, adjust the microphone gain and the monitor level of the radio.
5. LOCK key
This is a one-touch PTT key with a lock function.
When the LOCK key is pressed, the transmit mode is set and held, When the key is pressed again the transceiver returns to receive mode again.
**The operation of the PTT key is disabled when the LOCK key is operated.
The LOCK key indicator lights up red when the LOCK key is in operation.
6. PTT key
Press and hold down this key to transmit, and release it to receive.
**The PTT key has a built-in magnetic sensor. Strong magnetic items, such as a speaker or a magnet, may affect this PTT key, resulting in malfunctions.
7. On Air Indicator
This illuminates in red when in TX mode.
The indicator is off when in RX mode.
8. MIC
The unit includes a built-in dynamic microphone and a condenser microphone that is developed for communications equipment. The condenser microphone provides crisp sound with transparent frequency characteristics up to high frequencies. The dynamic microphone produces a thick, deep, warm sound quality that is suited for informal chatting. It is also possible to combine the audio output signals from the two microphone elements.

****The included treble boost cowling may be installed to block sounds from the sides of the microphone, resulting in unique frequency characteristics as if the sound were condensed with a peak response in the vicinity of 1 to 1.5 kHz. To install the cowling, press it straight on from the front to cover the microphone. To remove, slide it straight off.

9. Angle adjustment knobs
The angle of the microphone may be adjusted by loosening (turning counterclockwise) the knobs on the left and right sides of the pivot top. Place the microphone in the desired position and then tighten the knobs (turn them clockwise) to secure the microphone.

10. Height adjustment ring
The height of the microphone can be precisely adjusted. Turn the compression ring counterclockwise to loosen the top tube, and then raise or lower the top section to the desired position. Turn the compression ring clockwise to tighten it and hold the microphone in place.
****The stand can be extended to a maximum of 6 cm.

11. MIC Jack (8-pin)
Use the supplied microphone cable to connect the microphone to a transceiver that has a“modular terminal”.

12. MIC Jack (modular)
Use the supplied microphone cable to connect the microphone to a transceiver that has an “8pin terminal”.
