OWNER’S MANUAL — Please read before using this equipment.

Thank you for purchasing the RadioShack 
Race Scanner Intercom with Pit Crew 
Headsets. It enables up to four people to 
listen to a scanner and communicate at the 
same time. It comes with two headsets and 
a 3-foot cable to connect a scanner to the 
intercom. Additional headsets are available 
at your local RadioShack store.

longest battery life, we recommend 
RadioShack alkaline batteries.

Connect a headset for the person(s) on the 
left to either of the left side jacks (L) and a 
headset for the person(s) on the right to 
either of the right side jacks (R). This allows 
them to hear each other’s voice through the 
corresponding earpiece of their headset. For 
example, a listener on the right side will hear 
the other person’s voice in the the left 

earpiece. The scanner will be heard in the 
right earpiece. The listener on the left will 
hear the other person’s voice in the right 
earpiece. The scanner will be heard in the 
left earpiece.

To protect your hearing, follow these 
guidelines when you use headsets.

• Set the volume to the lowest setting 

before you begin listening. After you 
begin listening, adjust the volume to a 
comfortable level.

• Do not listen at extremely high volume 

levels. Extended high-volume listening 
can lead to permanent hearing loss.

• Once you set the volume, do not 

increase it. Over time, your ears adapt 
to the volume level, so a volume level 
that does not cause discomfort initially 
might still damage your hearing.

Do not use a headset with your intercom 
when operating a motor vehicle or riding a 
bicycle in or near traffic. Doing so can create 
a traffic hazard and could be illegal in some 
areas.

If you use a headset with your intercom 
while riding a bicycle, be very careful. Do not 
listen to a continuous broadcast.  Even 
though some headsets let you hear some 
outside sounds when listening at normal 
volume levels, they still can present a traffic 
hazard.
