6. To adjust the squelch, place the small plastic tool (included with the unit) in the hole marked SQUELCH at the
back of the unit, and slowly turn the tool to adjust the output level to just above the level of background noise.
Setting the squelch too high will reduce the range of the system. Setting the squelch too low will increase the
level of unwanted noise.
VH-120 DUAL CHANNEL WIRELESS SYSTEM
The VH-120 dual channel VH series wireless system is two separate single channel transmitters of different
frequencies transmitting to one unit that houses both frequency receivers. One output carries both frequency
signals to your mixer simultaneously through one cable.
Four different models are available and all operate on a VHF high band frequency between 174.60 MHZ to
204.60 MHZ.
THE MODELS AVAILABLE ARE:
VH-120M - which comes equipped with two hand held microphone transmitters.

HAND HELD TRANSMITTER FEATURES
• High sensitivity cardiod capsule for professional use
• Special noise absorption parts inside the barrels eliminating switch shock and handling noise
• Frequency with quartz locked control
CAUTIONS
1. Do not drop the microphone onto a hard surface.
2. Do not strike the microphone head front with fist or fingers, and do not blow strongly into the microphone head
front.
3. Do not use the microphone in areas of high humidity and/or high temperature as this could lead to damage of
the microphone.
HAND HELD TRANSMITTER OPERATION
1. Open the battery holder by turning it counterclockwise. Insert a 9V battery into the battery holder according to
the polarity indication marked on the battery housing. Close the battery holder.
2. Push the power switch to the ON position. The BATT indicator should flash once briefly as you turn on the mic
indicating that the mic has sufficient power. If the BATT stays on, it indicates that the battery has insufficient
power and should be changed. If the BATT does not light at all and the mic does not work, it indicates that the
battery is dead , and you should change the battery. If the microphone is not going to be used for any length of
time, push the power switch to OFF and remove the battery. Do not switch the mic on and off rapidly, because
you won't get a true indication from the BATT indicator.
