II. Assembly Illustrations

1. MU-13:

(A) Select a suitable size of single-sided earset (2). Attach the copper tube (4) into the microphone boom holder (3). A diagram shows the copper tube being inserted into the boom holder on the earset.

(B) Clip the cable and earset (2) together with the cable clip (1). A diagram shows the cable and earset being secured by the cable clip.

(C) Widen and adjust the earset proportional to fit the user's ear. Diagrams show the earset band being stretched and shaped to fit an ear.

(D) Bent inward to form an appropriate curvature. Diagrams show the earset band being bent to create a curved shape.

2. MU-23/MU-210:

(A) Select a suitable headset frame size. Attach the copper tube (4) into the microphone boom holder (10). A diagram shows the copper tube being inserted into the boom holder on the headset frame.

(B) Insert the cable by clipping into the headset clip (7). A diagram shows the microphone cable being clipped into the headset clip.

III. Wearing MU-13 Earset Microphone

Place the earset over your ear. Press against your earlobe and reshape it for a comfortable and snug feel. Diagrams show a person positioning the earset over their ear, with arrows indicating adjustment.

IV. Adjusting Headworn Microphones

1. MU-13:

For the ideal location, position the microphone boom (5) so the microphone is about 1 cm from the corner of your mouth. Diagrams show a head profile with the microphone boom positioned correctly near the mouth.

2. MU-23/MU-210:

For the ideal location, position the microphone boom (5) so the microphone is about 1 cm from the corner of your mouth. Diagrams illustrate head profiles showing the correct microphone placement relative to the mouth.

3. Caution:

⚠️ For distance and angle adjustment, only adjust the microphone boom (5). Don't bend the copper tube (4).

V. Wiring Illustrations

(3-Wire)

A diagram shows the wiring for a 3-wire connection. The connector pins are labeled: 1 & 2 Ground, 3 Audio, 4 Bias. The corresponding cable wires are Red (carrying 5V) and White.

VI. How to Obtain Ideal Sound Quality When Wearing Headworn Microphone?

1. Position the microphone and boom so that the microphone is about 1.0 ~ 1.5 cm (0.4 ~ 0.6-inch) from the right or left corner of your mouth to minimize breath or "popping" noise.

2. Omni-directional and Uni-directional types are available. The ideal way to wear the "Omni" type is to have a microphone capsule closer to the corner of the mouth with about 1.0 ~ 1.5 cm away (see Fig. 1 and 2) to minimize breathing or "popping" noise for ideal sound quality. (See Fig. 3).
Diagrams show:

• Omni-directional: A representation of a microphone capsule with a circular sound pickup pattern.
• Uni-directional: A representation of a microphone capsule with a directional sound pickup pattern.

3. "Uni" type is directional. During a live performance, it has stronger bass sound and higher dynamic range, better suited for "music" effect. However, the ideal wearing position for Uni is more complicated than Omni. Apart from the sensitivity level changes due to distances away from the mouth, it is more susceptible to the Proximity effect and popping noise. In theory, it is recommended to position a unidirectional capsule in front of the mouth for ideal sound quality. However, this position is vulnerable to the problems of popping noise and affects both types of capsules. In reality, the ideal wearing position for sound quality refers to Fig. 4 (about a 45-degree angle and 1.0 ~ 1.5 cm distance away from the edge of mouth).

4. An amplified system is recommended during soundcheck for adjusting the ideal microphone position.

Disposal

Dispose of any unusable devices or batteries responsibly and in accordance with any applicable regulations.

Disposing of used batteries with domestic waste is to be avoided!

Batteries / NiCad cells often contain heavy metals such as cadmium(Cd), mercury(Hg) and lead(Pb) that makes them unsuitable for disposal with domestic waste. You may return spent batteries/accumulators free of charge to recycling centres or anywhere else batteries/accumulators are sold.

By doing so, you contribute to the conservation of our environment!
