3. Press and hold the power switch for a few seconds (located on the base of the microphone). The power LED will
illuminate red and ‘ON’ will be displayed on the LCD screen. Note: power switch is more easily accessed with lower
housing removed.
4. A selection switch on the rear of the microphone provides three level settings (mute, mid & high) depending on the
application or environment in which it is to be used. Mute setting allows microphone to be put on standby without
switching the power off.
5. The LCD screen will display the channel selected. To determine which frequency this channel is operating on, press
the UP or DOWN frequency adjustment buttons.

number. You can cycle through the channels by pressing the UP or DOWN frequency adjustment buttons. Press the
frequency set button again to lock in your channel selection.
7. The battery status is displayed on the left of the screen. When battery capacity is critical the icon will flash three
times before switching the microphone off automatically.
8. To turn the microphone off press the power switch for a few seconds until the LCD screen displays ‘OFF’
9. When using with rechargeable NiMH batteries, connect a DC 5V plugpack (Altronics M 8909A plus M 9187 tip
adaptor) to the charging port on the base of the microphone. Charging time is dependant on the capacity of
batteries used, typically 10-12 hours charging is required. If battery icon is flashing when charger is connected,
ensure rechargeable batteries are inserted in the microphone. If batteries have failed, both the battery icon and
screen backlight will flash.
10. During normal charging the battery icon will cycle through the charge “bar” icons. Once full capacity is reached
the full battery icon and all “bars” will be displayed.
