BC346XT
The Complete Reference
This document provides a complete reference to all menus, functions, and
features of the BC346XT Handheld Trunk Tracker Scanner from Uniden. It
is based on the Operation Specification that is used both as a guide to the
software engineers for creating the scanner’s user interface and as a
repository for the “final say” on how every feature and function is
implemented.
Some proprietary information has been removed, formatting has been
modified, and extensive editing has been performed to make the text
more readable. However, you will almost certainly find a handful of odd
turns of phrases.
Mostly, though, we hope that this reference work can help you better
understand and use your BC346XT. This document isn’t intended to be a
guide for how to use your scanner…you’ll find that information in the
Owner’s Manual…but rather a reference for all the things that the scanner
does. Combined with the Owner’s Manual and the great resources
available to scanner users online, you now have more information than
ever on every facet of your scanner.

default values.
Although TV bands are listed, the BC346XT cannot decode Digital TV audio.
When you select “AUTO” for a channel or mode’s Modulation or Step, the above value is
used (unless you’ve edited the Band Defaults).

Channels
Dynamic –You can create up to 9,000 total conventional channels, trunked channels, and trunked system
frequencies.
Channels in a conventional system contain a frequency.
Channels in a trunked system contain a talk group ID (TGID).

Notes about limits:
The actual results will be limited by the first absolute limit you hit. For example, if you
have created 1000 sites, you will not be able to create a new system even though you have
created fewer than 500 systems.
You can check the % of memory used by using the menu.
Channel Memory Scan
The scanner can scan any combination of trunked and conventional systems simultaneously.
Priority Scan
The scanner checks conventional priority channels every 1-10 seconds (2 seconds default) when scanning a
conventional system.
Priority Plus Scan
The scanner scans only the conventional priority channels.
Search with Scan
The scanner can do Service and Custom Searches along with system scanning.
Scan Speed
100 Channels/Second (max) for conventional systems.

Scanning Lockout
You can lock out any System, Site, Channel Group, Channel, or search frequency.
Locked out channels are skipped (or ignored) during scanning.
If a system, site, or channel group is locked, all channels belonging to it will be skipped during scanning.
Temporary Lockout
Sites, Systems, Channels, or Frequencies temporarily locked out are automatically unlocked when power is
cycled.
Quick Keys
You can assign an SQK (System/Site/Search Quick Key) from 0-99.
You can assign a GQK (channel Group Quick Key) from 0-9.
Quick keys can be rapidly enabled/disabled from the keypad during scanning.
Startup Configuration
You can assign a startup configuration key to a system or search range so that it can be automatically
locked out or unlocked during power up.
Channel Alert
You can set a separate audible/visual alert for each channel.
Alpha Tagging
You can assign an alphanumeric name to each System, Site, Channel Group, Channel, Location, Custom
search range, SAME group, and Tone-Out. You can use 16 characters per tag.
Duplicate Input Alert
The scanner will alert you if an entered alpha tag, frequency, etc has already been used in the same
system.
Number Tag
You can assign a unique number tag from 0-999 to each system and to each channel within a system. This
tag allows you to rapidly tune to a specific channel.
Trunk Tracking
The scanner can track the following types of trunked systems:
Motorola Type I 800
Motorola Type II 800, 900, UHF, VHF
Motorola Rebanded
EDACS Wide, Narrow, SCAT
EDACS ESK (No ProVoice Decoding)
LTR
