Connect Systems Inc. -Model TP-154 Page 2
IMPORTANT NOTICE
Your TP-154 is equipped with CTCSS Trak... ,
a revolutionary software decoding algorithm that gives the TP-154
unbeatable tone sensitivity and talk down resistance.
This TP-154 is supplied with the ability to decode either the
standard 38 EIA CTCSS or 50 CTCSS tones tones and 104 DCS codes.
To select the number of tones, use JP-7. With JP-7 installed, you
decode 38 tones. With JP-7 removed, you decode 50 tones.
Consider carefully before you jump into the 50 tone version.
Dividing up the subtone spectrum into 50 slots rather than 38
slots gives each standard tone less operating room. The 38 tone
version makes the TP-154 more tolerant of mobile and portable
radios which have poor CTCSS frequency tolerance. We recommend
only using the 38 tone version because in general you will
experience far better system performance. The TP-154 also supports
104 DCS codes. Please see Table 2 for a listing of standard and
non standard tones and codes.
Our recommendation to avoid problems:
DO NOT USE THE 12 NON STANDARD TONES UNLESS ABSOLUTELY NECESSARY!
