This state of the art unit includes the latest features backed by a three year limited warranty. Prior to use, we suggest that you carefully read all the instructions. This book includes instructions for both the VH-101 and the VH-120 systems. 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. CAUTIONS 1.

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. VH-120L - which comes equipped with two belt packs and two lavalier transmitters. VH-120H - which comes equipped with two belt packs and two headset transmitters. ALL MODELS ARE AVAILABLE IN THREE SETS OF DIFFERENT FREQUENCIES: Frequency Conversion Chart: System Channels 1 1&5 2 2&6 3 3&7 4 4&8 Frequencies 174.60 MHZ/192.60 MHZ 177.60 MHZ/198.60 MHZ 180.60 MHZ/201.60 MHZ 186.60 MHZ/204.60 MHZ FCC RULES AND REGULATIONS Gemini wireless systems are the type accepted under FCC rules parts 74 and 15.

Then plug the adaptor into an appropriate AC outlet. Switch the power to the ON position. Note: The adaptor is available in 120V AC or 230V AC. 3. Extend the antennas fully vertical and point them toward the direction you will be speaking from. 4. Insert the 1/4" phone cable into the jack labeled AUDIO OUT on the rear of the receiver, and connect the other end of the cable to your amp, effects or mixer mic jack. 5. Adjust the volume using the level controls on the front panel. 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-101 SINGLE CHANNEL WIRELESS SYSTEM The VH-101 single channel VH series wireless system is a high quality audio product that provides excellent performance under most operating conditions. 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-101M - which comes equipped with a hand held microphone transmitter. VH-101L - which comes equipped with a belt pack and lavalier transmitter. VH-101H - which comes equipped with a belt pack and a headset transmitter. 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 ALL MODELS ARE AVAILABLE IN SIX DIFFERENT FREQUENCIES: Frequency Conversion Chart: Channel Frequency 1 174.60 MHZ 2 177.60 MHZ 3 180.60 MHZ 4 186.60 MHZ 5 192.60 MHZ 6 198.60 MHZ 7 201.60 MHZ 8 204.60 MHZ 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. VH-101 SINGLE CHANNEL RECEIVER OPERATION Note: Effective range between the transmitter and receiver is up to 150 feet. 1. Remove all packing materials. Save the box and packing material to transport the unit, and in case the unit ever requires service. 2. Plug the AC adaptor into the rear of the receiver where the jack is labeled DC 12V. Then plug the adaptor into an appropriate AC outlet. Switch the power to the ON position. Note: The adaptor is available in 120V AC or 230V AC. 3.

Open the battery door by sliding towards the arrow. Insert a 9V battery into the battery holder according to the polarity indication marked on the battery housing. Close the battery door. 2. Push the power switch to the ON position. The LOW BATT indicator should flash once as the switch passes MUTE indicating that the transmitter has sufficient power. If the LOW BATT stays on, it indicates that the battery has insufficient power and should be changed. If the LOW BATT does not light at all, it indicates that the battery is either dead or not positioned correctly, and you should correct the positioning or 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. 3. The lavalier mic clip should be placed as high as possible in a vertical line with your mouth. 4. To adjust the gain (input sensitivity), remove the battery door and place the small plastic tool (included with the unit) in the hole marked mic adj and slowly turn the tool and speak into the mic until the volume is adjusted. Use of any other tool to adjust the gain will void the warranty. 5. The lavalier wire is the transmit antenna. Do not roll up, coil or shorten during use. This wire must be kept as straight as possible.
