understanding the memory

All information contained in the scanner is stored on a microSD card supplied with the scanner, This includes Favorites Lists, all the radio settings, and the Radio Reference database,

favorites lists

Because the memory is based on the RadioReference database, the SDS100 has a different organization unlike banks and channels in older scanners, but more like Dynamic Memory Architecture (DMA) used for the last few generations of scanners, Favorites Lists follow the RR database structure of Systems that contain Departments that hold Channels (conventional frequencies or IDs) and then Sites to hold trunking frequencies, If you are familiar with DMA scanners, think of departments as being like channel groups,

Favorites Lists will allow you to store channels you find when you are scanning from the full database (the easiest way), They can contain channels from trunking systems and conventional systems, You can also manually add systems, (not single sites), departments and channels into Favorites Lists from the database as well as program new systems, departments, sites, and channels with the Sentinel software,

You can save up to 256 different lists in the scanner (and software) and associate them with any or all of your profiles. You can monitor one or more lists at a time and/or the database. You can also export your lists to a file to share them. Deleting a profile will not delete the lists associated with a profile. However, deleting a Favorites List will delete it from all profiles.


Systems hold all of your Sites, Departments, and Channels,

trunking sites

inside systems are trunked sites that hold the trunking frequencies for any trunking system and any band plan information needed. You need at least one site for each trunked system and some systems can have several sites.


Departments are created inside systems. Departments hold frequencies (channels) for conventional systems and Talk Group IDs (also called channels) for trunked systems.

sentinel software

manage profiles

Profiles are “snapshots” of your scanner’s set up. A profile contains all configuration settings as well as all Favorites Lists, Avoids, and System settings. Sentinel can save multiple profiles so you can restore different profiles as you need them. For example, if you regularly visit a specific location, you can create a profile for that location. You can save it to Sentinel to use whenever you visit.

manage favorites lists

You can create Favorites Lists in Sentinel then associate them with specific profiles. Sentinel lets you create new systems or edit systems already in a Favorites List. When a profile is written to your scanner, only specified Favorites Lists are written to the scanner. Note that all Favorites Lists are shared by all Profiles. If you delete a Favorites List, it is deleted from all profiles. If you want to use a particular Favorites List in some Profiles and not use it in Others, use the Download and/or Monitor settings in the Profile Editor to select your preference.

manage databases

Uniden updates the Database used in your scanner every week. You can decide how often you want to update the databases on your scanner. When you update them through Sentinel, it checks the website for the most current database and saves it in Sentinel. When you select Write to Scanner, the new database is updated in the scanner. Updating the main database does not update any Favorites List. Your customizations and selections are preserved.

how to install sentinel software

1.    Go to the scanner’s product page at Uniden.com and click the link for support files.

2.    Download the latest version of Sentinel.

3.    Unzip the file you downloaded, then click on setup.exe and follow the on-screen instructions to install Sentinel.

updating firmware

Your scanner updates its firmware through Sentinel. In that process, Sentinel connects to the internet and checks for the current firmware version to download.

From time to time, Uniden will release firmware updates to improve existing functionality, add new features, or address issues found in its operation. Updating the firmware takes just a few minutes and is easily accomplished using the Sentinel Software you installed on your PC.

Simply connect your scanner to your PC using the supplied USB cable and select Mass Storage. Then, in Sentinel select UPDATE/Update Firmware and follow the on-screen prompts.

For information about what is included in each update, see:


updating the database

1.    To update the scanner’s database, connect it to your PC using the supplied USB cable. Select Mass Storage.

2.    Next, in Sentinel, select UPDATE/Update Master HPDB.

3.    Finally, write the new database to your scanner by selecting Soanner/Write to Scanner.

data naming

Name any Favorites List, System, Site, Department, Channel, Location, Custom Search, Recording Session, Tone-Out, or SAME group using up to 64 characters.

To Enter a Character, turn the scroll control until the character you want appears. To move the cursor to the right, press the right soft key (>).

To move the cursor to the left, press the left soft key (<). To clear a character, press ./no.

To clear all characters, press./no twice. Press E/yes when finished to exit.

priority scanning

Priority Scan – When the scanner is scanning a Conventional System, it interrupts scanning, based on the Priority Interval and Max Channels settings, to check priority channels for activity. The more channels you have set to priority, the longer the interruption will be. The Favorites List(s) and System(s) containing the priority channel(s) have to be enabled (and not Avoided) or the scanner will display Priority Scan No Channel.

Priority DND – The scanner checks priority channels, based on the Priority Interval and Max Channels settings, only when not receiving other conventional channels so there is no interruption in scanning with conventional systems.

Priority ID Scan – This function is similar to conventional priority although there is no interruption during the transmission. Priority is checked in between transmissions, when the scanner is receiving the control channel, and during the channel delay period. The scanner can only look for priority IDs in the trunked system it is currently scanning.

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.

The highest priority is for channels in System Quick Key 0. The lowest priority is for channels in System Quick Key 99. Priority for priority channels in the same channel Department follows the order in which the channels were created.

To use Priority Scan, you must first set your Priority Channels.

To use Priority ID Scan, you must also enable Priority ID Scan for each system.

To toggle Priority Modes, press Func then ./no(Pri).

Priority is always on for a trunked system if enabled,

scanning order

With previous scanners, you selected banks to scan. With this scanner, you select Favorites Lists, Systems, Departments, and Sites to scan by assigning Quick Keys to them.

Scanning is performed in a mixture of FLQK order and SQK order. The scanner does not scan all Systems in one Favorites List and then move to the next List.

For each Favorites List with a quick key, starting with 0, the scanner scans each 0 SQK in FLQK order and then move to the next set of SQKs for each list.


FLQK 0, SQK 0; FLQK 1, SQK 0…. FLQK 98, SQK 99; FLQK 99, SQK, 99. Department and Site Quick Keys are scanned with each System.

Systems with the same quick key are scanned in order of creation.

The Database is scanned next, in order of creation. Then, Systems with no quick key (including created Quick Save Systems) are scanned and in order of creation.

Conventional Channels and Departments within Systems are also scanned in order of creation. IDs are not really scanned. The scanner checks for any activity in the trunking system and:

•    Displays all IDs when ID Search mode is set to On.

•    Displays only programmed IDs when ID Search mode is set to Off.

Next, any Custom Searches (enabled for Search with Scan) are scanned in order (Close Call Hits last).

Then, the scanner scans the Close Call ‘Hits with Scan’ system (if Unavoided). This is a system that automatically stores the frequencies found by Close Call. If the ‘Hits with Scan’ system has no frequencies, the scanner does not scan the system.

The scanner scans a system for the duration you set using the System Hold Time option. For trunked systems, the scanner moves to the next system after the hold time expires, the current transmission ends, and the channel delay expires. Conventional systems operate similarly, but all (Unavoided) channels are scanned at least one time regardless of the hold time setting.


Scanning Checklist:

1.    You must enable at least one Favorites List or the Full Database in Select Lists to Monitor.

2.    Favorites Lists or Systems, with Quick Keys assigned to them, must be enabled with quick keys or through Manage Quick Key Status.

3.    Service Types required for channels must be set to On.

Any Favorites List not assigned to a quick key, not Avoided, and set to On in Select – to Monitor will be scanned. Any System, Department, or Site (or Quick Save System/Department) not assigned to a quick key and not Avoided, will be scanned.
