a Microphone grille — Covers and protects the microphone acoustic port, through
which the VLH 102 receives audio signals. Do not block this grille while the
microphone is in use.
b Power LED — This bicolor LED, located above the Power switch, indicates the
microphone power, volume, and charging status as follows:
When the microphone is in use:
LED Color Indication
Green – steady Power is on and microphone is functioning.
Green – flashing Volume button is being pressed (volume is changing).
Red – flashing Low battery (One hour or less of talk time is left.)
When the microphone is charging:
LED Color Indication
Red – steady Battery is charging.
Green – steady Battery us fully charged.
Red and green – flashing Alkaline or damaged battery is detected.
c Power switch — Slide this switch up to power on the microphone and down to
power off or mute the microphone.

d Audio input port (Audio In) — Connect an MP3 player or other audio device to this
3.5 mm TRS jack for auxiliary audio line input. When a device is plugged into this port,
its audio is mixed with the signal from the internal microphone.
NOTE: Because the audio input is mixed with the microphone, pressing the
Volume buttons on the microphone affects the volume of the audio input device.
However, it is recommended that you use the volume control of the input device
instead of the microphone Volume buttons to adjust the levels of this input.
