headsets are designed for adults but they work perfectly fine for
children, too. They
come with foam tubes that may be used over the ear arches. Most remove or slide the foam rearward allowing
the speaker to sit closer to the ear. Put the headset on as if
it were a ball cap with the wire hoop behind your head. See
pictures above for a visual.
sides or the entire unit rearward so the speaker is near the auditory canal for optimal

kissing close to the mouth.
Please note that the microphones are not ideally positioned at the time
of the photo.
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 and noise canceling
and works considerably better pointed towards the mouth than
into the wind!
With some helmets it
works better to put the headset on prior to the helmet and with others it
is best to put it on after.
You may find it
beneficial to slightly bend and shape the hoop of the headset to optimize
fit and hearing ability. Before bending, we recommend
finding the optimal speaker position for your ear. Visually look
at the speaker and then with the aid of a mirror see where it rests in
relation to the auditory canal. A second way to
determine optimal positioning is to find the position that provides
maximum volume by moving the unit around on your ear while the
microphone from the other unit is positioned near a constant sound
source, such as a stereo speaker. Once the loudest position is
found, hold it in place and go to a mirror where you can shape and bend
the hoop to hold it at that level and flat against your ear.
After the ear and
positions are optimized, with the unit "OFF",
plug both headsets into the mic /earphone jacks on the right side of the
unit. Be mindful not to try inserting it into the charging
jack as forceful entry WILL
cause damage that is NOT
covered under warranty. If you have trouble reading the port
labels, we recommend marking them for easier reference.
Turn on both units by
rotating the Volume/On/Off switch downward. The Master Radio has a
black antenna and the Remote Radio has a gray antenna. Push the 'Talk' buttons
one time on both radios. Both 'Talk' lights will change to and
remain Amber, a must for
duplex communication between the radios.
forty privacy channels available. The dip switches are located
beneath the battery. They MUST be set to identical positions on
volume control. Pushing the rotary volume dial up lowers the volume
and turns the radio off. Raise the
volume by pushing the rotary dial downward while saying 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 in the same
room. Strive for low but satisfactory volume settings which will reduce or eliminate wind and traffic noise except during extreme
The captain and stoker
generally carry their respective units in a jersey pocket. Single
bike riders often carry them the same way. However, when riding
single bikes, if one person seems to always be out in front and
increased range is desired, it would be best for the 'leader' to carry
the unit in their rear jersey pocket with the 'follower' carrying the
unit in a small handlebar bag. This provides for a
line of sight antenna signal between radios that will provide up to .5
miles of range, in our experience, far exceeding the advertised .25 mile

3) Carefully plug
the charger into
'Charger Jack' (NOT THE HEADSET JACK!) making sure the connector
aligns with the pin. Use
caution when aligning the
plug so as to not bend the pin.
4) Plug charger into
an AC outlet. Make sure the outlet has power.
A red light next to the antenna should come on. If it does not, check to make sure
the charger is not plugged into the headset
6) Charge depleted
NiMH batteries for 7 hours but no more than 12 to prevent battery
damage. A good rule of thumb is to charge them 1.5 - 2.0 hours for every
hour they have been on. A wall timer works well to prevent over-charging.

System & Troubleshooting
Digital Wireless is very
easy to use and intuitive thanks to the simplicity of the unit and comfort
of the Ultra Headsets.
Is it normal to
experience extra noise, garbled sound and difficulty hearing when going down a hill at 30
mph into a 20 mph headwind with heavy traffic going by?
Any intercom system
open to the environment that amplifies sound is prone to picking up a combination of ambient
sound and wind noise. To minimize the potential and or eliminate it,
check the following in this order:
noise canceling microphones are directional. Make sure the mic faces your lips and does not
point in any other direction. To determine the directionality,
windscreen back one time to see where the mic points. Now

unnecessarily high volume settings with optimal headset
positioning. Make sure the headsets are pulled back on BOTH sides so the speaker is as close as possible
to the auditory canal and position the microphones kissing close.
Moving the wire hoop foam tubes back out of the way should move the
speaker in closer to the ear. It may work better to put on the headset after the helmet
before. Once headset positioning is optimized, the volume can be on a low
setting providing clear clean sound. You may find it beneficial
to slightly bend and shape the hoop of the headset to optimize the fit.
Before bending, we recommend finding the optimal speaker position for
your ear. Visually look at the speaker and then with the aid of a
mirror see where it rests in relation to the auditory canal. The
wire loop for most is shaped for the optimal position. A
second way to determine the optimal positioning is to find the position that
provides maximum volume by moving the unit around on your ear while the
microphone from the other unit is positioned near a constant sound
source such as a stereo speaker. Once
the loudest position is found,
hold it in place and go to a mirror where you can slightly shape and bend the
hoop to hold it level and flat on your ear. Also try moving the
hoop down where it loops behind your head as this will rotate
the speaker changing its position.
voltage may also cause this problem.
Try recharging your batteries.
We are now getting pops, snaps and crackle
sounds in our system. What causes this?
99% of the time
this is resultant of a poor connection from either dirty contacts or a
broken headset wire. Clean the plug on each headset with rubbing alcohol and
see if this solves the problem. A bit of dielectric or
"bulb" grease helps
maintain a good connection available from any auto parts store. The most vulnerable
components of any
intercom system are the headset wires as they are handled a great deal
over time and receive numerous inadvertent tugs and pulls.
With durability in mind we use a special sheathed wire with
reinforced ends. If the wire has been
broken, the headset needs to be replaced unless you are handy with a
soldering iron. Headsets are subjected to a harsh environment in our
application and sometimes take a beating until folks go through the
learning curve of not catching them on everything in sight and out of
Why has my volume dropped
even though it is turned up all of the way?
If your headset
and microphones are properly positioned, suspect low battery
voltage. You may recharge your batteries.
Why don't our units communicate with each
Red power light does not illuminate on either radio, the switch is either
off, the battery needs to be charged, or the battery needs to be plugged
first things to check are:
1) Make sure the batteries are plugged in and fully charged.
2) You are within a reasonable range of each other.
3) A Red Power LED and an Amber Talk LED (after both Talk
buttons have been pushed) are illuminated on
If you are unable to get an Amber color LED to remain illuminated on both
radios (a must for duplex communication), you should turn the radios off and start over
allowing everything to reset.
Turn the radios on by rotating the switches downward. You should
feel a click and see 2 LEDs illuminate on each radio.
Radio with Black Antenna should now have 2 LEDs lit.
Gray Antenna should now have 2 LEDs lit.
2) Press the Talk
button on each radio one time. The radio with the Black antenna
should have the "Talk" LED change to
Amber. The radio with the Gray antenna should also have the
"Talk" LED change to Amber after pressing the "Talk"
button one time. BOTH radios should now have
one Red LED and one Amber LED illuminated, a must for full duplex
(If a 'Talk' LED does not change and remain Amber, press the 'Talk' button
one more time and see if it changes and remains Amber. If it does
not, shut both radios off again and start the power up process over
3) Turn the volume up to a satisfactory level by rotating the thumb
dial downward on both radios.
Lastly, there are dip switches below the battery that must be set to the
exact same sequence on both radios, something necessary for both radios to
communicate and for both 'Talk' LEDs to remain Amber.
Why won't one or both of our batteries charge?
1) Make sure
the battery is plugged into the radio. New units are often shipped with the batteries
unplugged as is common with new electrical devices.
2) Check to see if the charger is plugged into a
"live" outlet. You can imagine the 'true' stories we have heard over the years!
Verify that the
charger is plugged into the port on the left side of the unit. More than one person
has plugged their charger into the headset jack.
Rotate the Volume / ON-OFF switch downward all the way to make sure it is
in the OFF position. The charger cannot get ahead of the battery
drain if the radio is left ON.
On the outside chance a charger has failed, try charging with the 2nd
charger that came with the system.
Our batteries don't last very long. Why?
most common cause of this situation is not having the batteries fully
charged before starting to use them. Fully charged batteries do not
stay charged when allowed to sit without use. Charge the batteries
within 48 hours of use. If your batteries have
been dormant and off of the charger for more than a day or two, top them
off by plugging them in for an hour or so before your ride, longer if it
has been a few days. You should get ~4.5 - 5.0 hours out of new
fully charged batteries while in the full duplex mode.
We ride single bikes and get intermittent
bleep outs when getting close to .2 miles apart. Is this normal?
Yes, especially when
carrying both units in rear pockets given line of sight is lost between antennas
increase your range it would be best for the 'leader' to carry the unit
in their rear jersey pocket with the 'follower' attaching their unit to the
handlebar via a small handlebar bag. This provides for a line of sight situation
between radios. The radios essentially work like a home cordless phone in
that certain objects, bodies, high tension lines, etc. will all interfere with
the signal. A 1/4" range advertised by the manufacturer is under
ideal conditions. We have attained an unbelievable near 1 mile range with
two radios being on top of hills across an open valley. It is NOT supposed
to work that well!
I hear strange rhythmic sounds at times
coming from the speaker.
phones that are in close proximity to the radio will produce sounds as the
phone switches from one tower to another.
