Guided Tour - VT3L / VT3
5: Power on-off switch* - Use this to turn the VT3L / VT3 on or off (to conserve battery
power, be sure to leave it off when not in use).
6: Gain control (trimpot) - This input sensitivity control has been factory preset to provide
optimum level for the particular lavalier or headset model being used (in the case of the
VT3, it is preset for optimum instrument level) and so we recommend that this not be
adjusted manually. If necessary, however, you can use the supplied plastic screwdriver
(see #8 below) to raise or lower the VT3L / VT3 Gain control. See the “Setting Up and
Using Your VHF TD Series / VHF Series System” section on page 10 in this manual for
more information.
7: 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 VT3L / VT3 and will void your warranty.
8: Plastic screwdriver - Specially designed for use in adjusting the VT3L / VT3 Gain
control (see #7 above) and/or receiver Squelch control (see #4 on pages 3 and 5). See the
“Setting Up and Using Your VHF TD Series / VHF Series System” section on page 10 in
this manual for more information.
* 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.
