Section 3.0 Operation
3.1 Introduction
Information in this section consists of the functional and operational procedures for the UT12-000
Universal Tone Encoder/Decoder.
3.2 General
The UT12 is capable of encoding and decoding 5-tone CCIR tone sequences and encoding DTMF tones.
It is compatible with the NAT Tac/Com system, and when used in conjunction with a TH-series Tac/Com
control head and NTX series transceiver it provides broader and easier control over radio communication.

Controls and Indicators
3.3.1
MON (Monitor) Switch:
The monitor switch is a two position locking toggle switch that can select between
OFF
and
ON
.
When in the Monitor
OFF
position, transceiver audio from the current channel (or home channel when
scanning) is only heard if the correct tone ID sequence is decoded.
When in Monitor
ON
position, transceiver audio from the current channel (or home channel when
scanning) is always heard.
The following functions are unaffected by the position of the MON Switch:
Transceiver audio is always heard from the priority scan channels, guard receive channels, and list scan
channels with correct tone sequences; Transceiver audio from list scan channels that do not have correct
tone ID sequence is not heard.
