Technical Information


This manual is intended to serve as instructions for the use and care of the FanComm portable, weather-resistant BELLY-PACK intercom models, FC-2BPR and FC-4BPR. Please read this manual thoroughly before you use the intercom at the race track. The BELLY-PACK is portable and can be demonstrated in the comfort of your living room or office.

Your FanComm BELLY-PACK Intercom has been designed for years of trouble-free use and added enjoyment to your racing hours. We use quality components, fully trained and skilled U.S. workers that utilize a rigorous quality assurance program to assure the best quality possible at an affordable price. The Nylon belly-pack FanComm Velcro belt will adjust to fit most operators or can be adjusted to fit along side a cooler or in a backpack. The intercom has an ability to listen to two Scanner radios at the same time.


The intercom operates independently on its own 2, 9 VDC batteries and should last for about 40 hours of use. When turned "ON" with the switch under the volume control knob, an activated Scanner radio's signal will enter the Intercom and into the headsets. When using 2 Scanner Radios, the operator can randomly select the radio of choice to each individual listener. Set each Scanner's volume first. The toggle switches on the panel allow a selection of RADIO #1 or RADIO #2 to any of the listeners. The Intercom's volume control sets the maximum level into everyone's headset. Each FanComm Headset has individual controls so everyone can set their own personal listening comfort levels.


The FanComm headsets are available with and without microphones. Using Microphones offers a new dimension to the enjoyment of the fan who can listen to the race and also comment about the race without yelling to friends over the track noise. The Intercom has a VOX (a voice operating squelch circuit) control that turns the Intercom "ON" automatically when any one speaks and turns it "OFF" automatically when everyone is finished talking. The FanComm headsets blocks out the unwanted noise of the racing activities by an EPA measured -24 dB (decibels). Permanent hearing loss occurs when a sustained noise is louder than a -90 dB. Track noise can exceed 110 dB during times. The headset protects your hearing by limiting the amount of noise that reached your ears. The intercom allows for more normal conversations and reduces the need to yell to be heard.


To use the intercom, simply plug all headsets into the BELLY-PACK jacks marked HEADSETS on the outside of the nylon case. Fully engage the 3.5 mm STEREO plug of the Headsets. Move the "VOLUME" control clockwise until you hear a "click". For this test, turn the "SQUELCH" knob until the white mark is at the 12:00 o'clock position. This will vary depending upon the amount of track noise the microphones are exposed to during use. Turning the SQUELCH to the right (clockwise) makes it less sensitive to the track noise. During extremely loud noise, you may find it necessary to disable the VOX to keep the track noise from turning the VOX on when you don't want it on. Check the microphones positions of everyone and then check to see if the Intercom VOX is working automatically. It should turn on or off moderately easily. IF not, turn down the squelch knob until it does.


Position all users microphones to the outside half of the lower lip and just off the lip, no more than 1/8 inch. [CAUTION.... Most users forget to keep the microphone in this position which will deliver a low signal to the mike making their mike ineffective to turn the VOX circuit off and on]. Now set the Intercom volume to where is comfortable for everyone. Each user can individually adjust their own volume control on their headset. The microphones are the "ears" into the intercom. A weak and "timid" voice is not what the Intercom wants to hear. Tell your users to speak loudly and sharply when they want to speak. Keep the Headset's mike muffs on at all times to prevent wind-noise from disrupting the squelch VOX circuit.
Now,...... Remember to turn it "OFF" when done.


The introduction of scanner radios in the 8O's was a boom to communications for the racing Fan. Many radio manufacturers set their own standards for input impedance, power and interface standards. Today, the 3.5 mm connector is in popular use to connect the Scanner to Racing Headsets and intercom Systems. The FC-2BPR and FC-4BPR intercoms will not draw power from your Scanner battery. Battery life may be affected by this change as some Scanners attempt to draw power from the Intercom.


LOW BATTERY: The voices in the intercom will become garbled and be unclear when you use the intercom.

DISTORTED AUDIO: Due generally to low battery. Check battery to see that the battery clip connections are secure and retest.

BUZZER "HUM" WHEN I CONNECT HEADSETS: This is an alert to everyone that a headset has become partially disengaged. There is no damage to this safety alert.

SOMETIMES THE MICROPHONES DON'T WORK: The position of the microphone to the mouth is VERY important to Intercom's functioning VOX (voice activated exchange). The more race track noise, the closer the microphone must be to the mouth to turn "ON" and "OFF" the VOX circuit. At times during the race it may be advisable to turn the SQUELCH clockwise (CW) to the maximum possible. This disables the VOX until the noise conditions have passed.

HEADSETS DON'T WORK: Check to see that the headset is fully engaged into the jacks of the Intercom. Check that the volume control on the headset is turned up. Check to see the Intercom is turned ON and the VOLUME is turned up to hearing levels.

THE SQUELCH DOESN'T WORK: Check the position of your microphones to the mouth. Due to increased track noise, (and the higher squelch setting), the microphone position to the voice source will become more critical and requires a more "hefty" effort to turn it on. Move the mike as close to the mouth as possible to overcome the noise from the track.

HEADSET IS TOO TIGHT AND UNCOMFORTABLE: The FanComm headsets are designed with headbands that can be stretched without damaging them. Place your palms under the head pad, put your thumbs on the top of the head pad and gently flex the headband outward. Do this gradually it steps until the fit is comfortable. The looser the fit, the more noise you will hear.
