all 5 channels of the MURS frequencies. MURS is short for Multi-Use
Radio Service and is a newly created service by the FCC in the
United States. It is a low power, short range service in the VHF

"We purchased the MURS 4 Mile Range and MURS
Commercial Intercoms because one of our Preschool classrooms
is far removed from the office
- there was no way of
communicating electronically/ rapidly which is of special
concern in case of emergency. We decided to purchase the
outdoor Callbox XT to put out on our playground.
The classroom piece of the intercom has
saved much frustration and time simply by eliminating the
need for a staff member to either leave her classroom to
walk to the office or vice versa. Our office staff (one of
whom is handicapped) LOVES them because they don't have to
get up and down repeatedly to deliver messages/ gather
information, etcetera. It's all done through the new
intercoms. They provide peace of mind in case there is an
emergency." -- Stephanie
