1 Introduction
Welcome to eXtreme Radio Service (eXRS). TriSquare has
revolutionized 2-way radio communications with the eXRS
radios. What is eXRS? It uses a stealth military technology
redesigned by TriSquare for general use and operates using
Frequency Hopping Spread Spectrum (FHSS) technology in
the 900MHz ISM frequency band. eXRS radios provide
private and secure communications without interference,
and provide the longest range possible, compared to other
UHF radios*. With advanced digital technology, you get
unmatched clarity and years of trouble-free service. eXRS
radios do NOT require an FCC license and can be used by
people of all ages for any personal or business purpose.
*The usable range of eXRS is equivalent to or greater than that of other portable
UHF two-way radios (including FRS/GMRS). Usable range of UHF radios
varies significantly with the conditions of use. For example with large or many
obstructions between users, range could be less than a mile, and with clear (line-
of-sight) between users, range could extend to more than one hundred miles.
2 Getting Started
Thank you for purchasing the TriSquare TSX300 eXRS two-
way radio. Your TriSquare eXRS radio is a unique two-way
radio and a powerful communications tool that will give you
years of trouble-free service if cared for properly. Read the
owners manual carefully before operating the radio.

To use your new TriSquare eXRS radios, you will need to
install 3 ‘AA’ alkaline batteries, or the optional TriSquare
model TSX-BP NiMH rechargeable battery pack. To install
batteries, first remove the belt clip or swivel the belt clip to the
side. To open the battery compartment door, while holding
the radio face down, use your thumbnail to lift upwards
(towards the top of the radio) on the battery compartment
tab, and continue to lift the battery compartment door up
and remove. If you are using 3 ‘AA’ batteries, insert the
3 ‘AA’ with the correct polarity as indicated by the battery
diagram on the inside of the battery compartment, matching
the positive (+) and negative (-) terminals of the batteries to
