Guided Tour - UH1
1: Audio on-off switch - When set to the “on”
position, audio signal is transmitted. When set to
the “off” position, the audio signal is muted.
Because the carrier signal remains during muting,
no “pop” or “thud” will be heard. Note that turning
this off does
not turn off the transmitter power—it is
simply a way to temporarily mute the transmission
of audio signal. If you don’t plan on using the
transmitter for extended periods, turn off the
transmitter power by using the power on-off switch
(see #3 below).
2: Battery level meter - This set of three
multicolor LEDs indicates relative battery power,
indicating whether the installed battery is at low
(red), mid (yellow) or high (green) strength.
One of these will light whenever the UH1 is
powered on (see #3 below). When the red “low”
indicator lights, RF performance is degraded and
the battery needs to be replaced.
3: Power on-off switch* - Use this to turn the
UH1 on or off (to conserve battery power, be sure
to leave it off when not in use).
4: Microphone Input Level control (trimpot) -
This input sensitivity control has been factory
preset to provide optimum level for the particular microphone capsule provided with your
UM1 system and so we recommend that this not be adjusted manually. If necessary,
however, you can use the supplied plastic screwdriver to raise or lower the input level.
See the “Setting Up and Using the UM1 System” section on page 8 in this manual for
more information.
5: Battery holder - Insert a standard 9-volt alkaline battery here, being sure to observe
the plus and minus polarity markings shown. We recommend the Duracell MN 1604 type
battery. Although rechargeable Ni-Cad batteries can be used, they do not supply
adequate current for more than four hours.
WARNING: Do not insert the battery
backwards; doing so can cause severe damage to the UH1 and will void your warranty.
* Be sure to mute the audio signal at your external mixer or amplifier before turning
transmitter power on or off, or an audible pop may result.
