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.

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)

Multi-Site System
All trunked systems can have more than one site. All sites in the system share the same Channel Groups
and Channels.
Control Channel Only
Trunk Tracking can be achieved by entering only the control channels for Motorola systems.
Priority ID Scanning
Trunked channels can be assigned priority. When the scanner is monitoring the control channel, channels
you tag as priority are given a higher priority over non-priority channels when they become active.
Preemptive Priority ID Scanning
For Motorola systems that have channel priority active on the system, if you flag a channel as priority and
the system also has that TGID identified as a priority channel, the scanner will preempt any current
transmission if the TGID becomes active.
Trunking Activity Indicators
The scanner shows all trunked activity when you hold on the control channel.
Custom Search
You can program up to 10 custom search ranges and either search them exclusively or include these
searches when scanning.
Quick Search
If you hold on a conventional channel, you can start searching from the current frequency. If you hold on a
trunked channel, you can quickly switch to ID Search mode.
Frequency Autostore
The scanner can automatically store frequencies found during a search.
Search Speed / Turbo Search
100 Steps/Second in search mode (max, except for 5 kHz steps)
300 Steps/Second in search mode (max, 5 kHz steps)
Turbo mode automatically applies to 5 kHz step searches.
Search Lockout
You can lock out up to 500 frequencies.
The limit of temporary L/O frequencies: 250
The limit of permanent L/O frequencies: 250
Locked out frequencies will be skipped in Search Mode or Close Call Mode.
You can review all locked out frequencies in Menu Mode.

Thursday, May 14, 2009
12
Search Key
Search keys are short cuts to start searching for a single search range.
There are 3 search keys (sr1 to sr3).
Service Search
You can search preset frequencies typically used by specific agencies or groups.
The kind of Service Search is as follows: Public Safety, News, HAM Radio, Marine, Railroad, Air, CB Radio,
FRS/GMRS/MURS, Racing, FM Broadcast, Special
Broadcast Screen
Allows the scanner to ignore hits on Pager, FM, UHF TV, VHF TV, NOAA WX and custom band frequencies.
Attenuator
You can attenuate the incoming signal for channels that get interference from strong signal sources.
You can set a global attenuator to apply attenuation to all reception.
Code Search
Rapid search for the CTCSS/DCS used during a transmission.
Volume Offset
Adjust the volume level for any channel from -3 to +3 steps to balance audio level.
IF Exchange
Switches the current frequency to use a different IF (intermediate frequency) for receiving radio signals to
avoid interference.
Dropout Delay
Controls whether the scanner pauses at the end of a transmission to wait for a reply.
You can set the Delay time for each System. All Channels in the System share the same delay setting. You
can also set the Delay time for Search, Close Call and Tone-Out.
You can set the minus delay time. In that case, the scanner only stops on transmissions for the set
duration, then automatically resumes.
Weather and SAME Alert
The scanner can alert to Weather Alert Tone, all FIPS or selected FIPS.
Close Call®Frequency Capture
The scanner can immediately detect and lock onto a transmission above threshold signal strength.

Thursday, May 14, 2009
13
Close Call Temporary Store
The scanner scans the last 10 frequencies captured by Close Call so that you can continue to receive the
signal even after the signal is not strong enough to trigger a Close Call hit..
Tone-Out Sequential Decode
Lets you set the scanner to act as a two-tone pager for fire tone-out standby. If you do not know the tones
being used, the scanner can detect the tones when it receives a page.
Location-Based Scanning*
The scanner can automatically lock and unlock systems, sites and channel groups based on your current
location as provided by an external GPS unit (not included).
Location Alert System*
The scanner alerts you when you approached a stored location.
Navigation Modes*
Indicate the Direction / Distance / Time to Goal for locations you set.
GPS Compatibility*
Compatible GPS units output location data that conforms to NMEA-0183 v3.01. The scanner uses the GGA
and RMC sentences as defined by that specification. Note that this standard specifies an RS232 serial
connection. GPS units that have USB connectivity are not compatible with this scanner.
Wired Cloning
You can clone all programmed data, including Memory Architecture, Menu settings and other parameters
from one BC346XT to another BC346XT connected with RS232C cable.
Band Scope
Band Scope Mode searches a frequency range and displays a graphic of the signal level in real time.
In Band Scope Hold Mode, the user can monitor the frequency displayed.
PC Control
You can download information into the scanner and control the scanner via your personal computer.
LCD and Keypad Backlight
The Display Keypad backlight is orange.
The backlight can be adjusted to 3 different brightness levels
Alert Tone Level
