Tandem-Com Digital Wireless III Instructions

Please Read: 1) Charge the batteries. 2) Set up the system outside, in the real world, not inside. 
Two or more cell phones, on the same call, in close proximity, result in echos, poor sound, and feedback, same for intercoms. 
A low volume setting and a distance between the units prevents echos from both mics, simultaneously, picking up the same person talking.



The headsets are shaped to fit adults or children. 

The goal of optimizing the headset speaker and mic positions is to enable the lowest volume possible. The speaker needs to be in line with the auditory canal and the microphone close to the lips.

The speaker must be close to the auditory canal in order to use a low volume setting, necessary for optimal function. Most slide the foam tubes rearward to move the speaker closer allowing for a lower volume setting.

You may shape the wire hoop to your fit needs. For larger ears, increase the arch over the ear by pushing the wire forward while firmly grasping the speaker.

Put the headset on as if it were a ball cap with the wire hoop behind your head.   The wire loop does not touch the back of the head as pictured.

Adjust the microphone so it close to the mouth and not under your chin.

Make sure the actual microphone, under the foam wind screen, points towards the mouth and not into the wind. Pull the foam cover back one time to visualize which way the microphone faces, after which you will be able to tell by feeling its shape through the foam.   The microphone is directional, digital, and noise canceling. They work great when pointed towards the mouth and not into the wind!

For some, it works better to put the headset on prior to the helmet and with others it is best to put it on after.  


With the unit "OFF", plug both headsets into the headset ports. Make sure they are plugged in all the way!

Turn the Black Master radio on first. Firmly press the Power Button until you feel a click and hold until the buttons light up blue. Release the button and they will flash blue.
Turn the Grey Remote radio on second. Firmly press the Power Button until you feel a click and hold until the buttons light up in a blue color. Release the button and both radios will have all buttons illuminated in blue. Repeat with any other Remote radios. 

Adjust the respective volumes using the + and - buttons. A small beep is heard when pushing the buttons. Say test words, like the commercial, "Can you hear me now?" or like our then 4 year old got us to doing, "Blah, blah blah!", in a normal voice as if speaking to someone several feet away.  Strive for low volume settings which will eliminate echos, wind, and traffic noise, except in extreme conditions. If one or both headsets does not seem to function, check to make sure both headsets are plugged in all the way. Also, see if there is a Mute Button (not on every headset), located on the cord, that may have one or both microphones turned off.

To turn the radios OFF, firmly press the Power Button, feeling for the click, and hold, on each radio, until the buttons turn red. They will flash momentarily as it powers down. The radio is off when the buttons are no longer illuminated.

Riders generally carry the radios in a jersey pocket.  If riding single bikes with one person generally out in front a distance, it would be best for the 'leader' to carry the unit in the rear pocket with the 'follower' carrying the unit in a small handlebar bag providing line of sight between the antennas. This will provide up to .5 miles of range under ideal conditions, far exceeding the advertised .25 mile range.





1) Insert the batteries into the smart charger. Red = Charging. Green = Fully Charged.

2) Being a smart charger, there is no concern of over charging the batteries.
