Advanced System Identification
- It appears that my trunk system needs a custom band plan but it isn't in the RadioReference Database. How can I figure it out?
- See the Uniden Band Plan Entry
Capturing Live Audio
It has been reported that the majority of current models have a stereo output jack for headphones instead of the traditionally-found mono jack. This creates a peculiarity when capturing live audio with a computer because the volume level with the scanner will be about half of the expected volume level if you're using a mono capture cable. There are two ways that this can be addressed easily:
- Stereo Input Cable - You can always use a stereo cable to connect the scanner to your capture device as long as your capture port is also stereo (Line In). You should not use this method if you're capturing with a mic port as the mic port is mono, not stereo.
- Stereo to Mono Converter Plug - You can potentially use a stereo to mono adapter (such as this one) to convert the audio. You'll have to use this option if you're capturing with a mic port.

Control Channel Only
- What is Control Channel Only and what does it apply to?
Digital End Code Detection
- What is Digital End Code detection and why do I want to use it?
Fire Tone Out
- How do I use the Fire Tone Out & Fire Tone Out Search feature?
Go Directly to a Frequency / VFO Mode
Can I go to a frequency directly without programming it into a system? Is there a VFO function?
- Press HOLD, key in the frequency, then HOLD (not Enter). Then you can SCROLL to step frequency up or down the band, pressing HOLD again starts a Search from this point.
How do I go directly to a channel?
- While in HOLD mode, hit FUNC-7 (RCL), then select the system, group, and channel.
- Hit the HOLD button, then press the FUNC button and SCROLL to the system you want (using the scroll knob). When you get there, release the FUNC button and scroll to the channel you want. [Hint: If it's near the end of the list, scroll to the NEXT system then scroll backwards through the channels. The first scroll backwards will return to the previous system]

ID Search to ID Scan
Display shows "ID SEARCH". How do I get back to "ID SCAN"?
- While on that system, press the FUNC key and then press the SCAN button. You can also do it by just pressing the SCAN button while there are no active TGs on the system. In models with HP in the naming turn ID Search OFF in the System.
Location Based Scanning
- What does Location Based Scanning do for me? How does it work?
GPS Mode (XT scanners only)
- For undocumented hacks, please see our DMA Scanner Hacks article
- For basic test modes typically technicians use to access hidden features, any user could try and see what might work, please see our Uniden scanner test modes article.
- Don't forget that pushing down on the scroll knob is the same as pushing the "Yes"/"E" button.
- Pressing the on/off button briefly will take you out of the menu system.
- Holding down 1,3,0 and Pressing power will bring up the NWR-SAME TEST. Press the Menu Button to test the tones.
- Frequency 'tune' mode: While in scanning mode, press HOLD, key in the frequency, then press HOLD. The scanner stays on this frequency. This also works for talkgroups (hit . twice for a dash). An error message is displayed if you enter a talkgroup while scanning a conventional system.
BCD996T Talkgroup and Frequency display when scanning
Use display mode #2: Toggling the Display Mode To change the display so the channel and frequency or Talk Group ID appear instead of extended channel information, hold on any channel then press F + . The scanner displays Display Mode 2. To return to Mode 1, press F +  Mode1 indicates the channel data under the Channel Name. Mode2 indicates the frequencies under the Channel Name for Conventional systems or the TGID number for Trunked systems.
