The T-2350 is a synthesized VHF, digital and analog audio transmitter with a
software selectable power output of 1 Watt. The T-2350 has an optional
removable Mini SD

TM

 Card that can record approximately 1 minute of audio in

WAV file format per MB of storage.

The T-2350 has 10 programmable channels. It is designed for body worn
personal protection and evidence gathering missions. Its miniature size and
rugged design insures safe concealment and long lasting performance. The
time to half power with fresh AAA  Alkaline batteries is 5 hours. The transmission
is programmable for digital P25 clear, digital P25 encrypted, analog
narrowband, or analog wideband operation. The T-2350 transmission is either
duplexed on the mic/antenna cable (meaning the microphone is the antenna)
or transmitted on a stand-alone noodle antenna, in which case the internal
microphone or remote microphone must be used.

Concerned with the rapid evolution of digital communication technologies and
a need for interoperability, the Association of Public Communications safety
Officials (APCO) developed an open architecture, digital standard for public
safety and government communications systems. Products compliant with
APCO Project 25 standard are interoperable, regardless of the manufacturer.
The National Telecommunications and Information Administration (NTIA) has
adopted the APCO Project 25 interoperability standard, also known as TIA/EIA-
102. The T-2350 is compliant with this standard.
