Guided Tour - VH3
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 VH3
for extended periods, turn off its 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 or more of these will light whenever the VH3
is powered on (see #3 below). When all three are
lit, the battery is at maximum strength. When only
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
VH3 on or off (to conserve battery power, be sure
to leave it off when not in use).
4: Gain control (trimpot) - This input sensitivity
control has been factory preset to provide optimum
level for the particular microphone capsule provided with your VHF TD Series or
VHF Series system and so we recommend that this not be adjusted manually. If neces-
sary, however, you can use the supplied plastic screwdriver to raise or lower the input
level. See the “Setting Up and Using Your VHF TD Series / VHF Series System” section
on page 10 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 VH3 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.
