Mototrbo R2.4 Firmware Release
- Jan 21, 2015
Motorola released new Mototrbo System R 2.4. This latest system release covers all currently shipping MOTOTRBO portables, mobiles and repeaters as well as the CPS and other software tools. The release includes several enhancements, including:
The User Selectable Audio Profiles provide radio users with greater flexibility to optimize the audio experience for specific operating environments and to better accommodate personal listening preference.
Audio Ambience – Based on work enviroment:
- Default – Original radio settings
- Loud – Enables Noise Suppressor and increases speaker loudness by around 8dB, so the radio is easier to hear over surrounding noise
- Work Group – Enables AF Suppressor and disable AGC, to minimize feedback loops, when a group of radios are near to each other
Audio Profiles – Based on listening preferences:
- Default – Original radio settings
- Level 1, Level 2, and Level 3 – Intended to compensate for noise-induced hearing loss that is typical for adults in their 40’s, 50’s, and 60’s or over
- Treble Boost – For a brighter or high pitched sound
- Mid Boost – For a more nasal sound
- Bass Boost – For a deeper sound
Selections should be made from each category as follows:
All users in a given work environment should select the same Audio Ambience. Users are encouraged to select the Audio Profile which sounds best to them.
This functionality is not available for: SL1600, DP1400, DM1400, DM1600
Radio industry standard AMBE2 vocoder recognises the sounds made by the human voice and converts them to a set of highly-optimised codes. Vocoder algorithm does not reproduce well the Trill (rolling “r”) sound in Latin languages and transforms it into a flattened “r” which has an impact on clarity and intelligibility. Additional audio processing is applied in the transmitting radio to enhance the sharpness of the rolling “r” so speech is clearer and more intelligible in the receiving radio(s).
Screen Backlight Enhancements
The display Backlight for MOTOTRBO portable radios can now be customized to allow users to configure when the light turns ON and for how long it remains active. Choices: 5, 10, 15, 20, 25, 30, 40, 50, 60 seconds and Infinity (∞)
(Infinity does not apply to SL4000 series)
Text to Speech Voice Announcement
Standard Voice Announcement in 2nd Generation MOTOTRBO radios audibly conveys information to the radio user when the radio display is not easily accessible. Professionally recorded or user recorded files are loaded into radios via the CPS.
Text to Speech Voice Announcement generates the voice announcement using a speech algorithm in the MOTOTRBO subscriber for Channel and Zone Names, Button Functions, Text Messages and Job Tickets.
- 27 languages and country accents:
- Arabic (1), Cantonese (1), English (7), French (2), German (1), Hungarian (1), Italian (1), Japanese (1), Korean (1), Mandarin (1), Polish (1), Portuguese (2), Russian (1), Spanish (4), Swedish (1) and Turkish (1)

IMPRES Over the air (OTA) Battery Management
Battery Fleet Management can support automatic collection of battery information over the air while the radios are in use. This removes the need for wired network connections, Charger Interface Units, and remote clients at charger locations.
It is important to note that over the air battery management focuses on managing the long term health of the batteries. It is not meant to acquire the current real-time energy levels of all radios within the system
