Application settings

Configure the application using the gear icon on the login screen or by tapping Settings in the navigation drawer. The version information can be found at the bottom of the screen.

The following settings are mandatory for T.Flex to begin working:

  • User name

Changing these settings can be disallowed by your TASSTA administrator in T.Commander.

You can hide settings on the client side by disabling the Allow Settings option. Note that this removes the Settings item from the navigation drawer altogether. The settings become hidden the next time you log in.

The following tables list all of the options and features available in the T.Flex Settings menu. Configure them in accordance with your network policy and operational environments.

Audio settings

Parameter Description
Redirect voice to loud speakers Whether to use the loudspeakers for voice output instead of the internal speaker. This setting is intended to work around the problem of audio feedback whenever possible.
The following options are available:
  • Never – always output sound to an internal speaker
  • Defined by proximity sensor – Output sound to the internal speakers when the proximity sensor detects obstruction; otherwise, use the loudspeakers
  • Always when one user talks – This is the recommended option
  • Always – Always output sound to the external speaker or loudspeaker; this option is the most likely to cause audio feedback, making it harder for others to make out what you are saying
For details about configuring sound outputs, see Voice communication.
Audio Effects These Android system settings help improve your listening experience
  • Acoustic Echo Canceler – Ensures that the person who is talking doesn't get the echo of their own voice from the loudspeaker; this functionality is usually provided in hardware and is not available on all devices
  • Noise Suppressor – Audio pre-processor which removes background noise from the captured signal; this functionality is usually provided in hardware and is not available on all devices
  • Automatic Gain Control – Audio pre-processor which automatically normalizes the output of the captured signal by boosting or lowering input from the microphone to match a preset level so that the output signal level is virtually constant; this functionality is usually provided in hardware and is not available on all devices
  • Event and Voice in same output – Whether to redirect event sounds and voice to the same Android audio route so that you can use the same volume control for both
  • Mic Level Control – Ensures that the microphone volume is controlled by T.Flex and prevents the system from automatically reducing it
  • Mic Volume level – Lets you increase the microphone level (select **higher** or **highest**) on devices where its factory settings are low; this works by increasing the microphone gain, so the audio quality may degrade noticeably
  • On GSM call disable Event sound – Mute event sounds during a GSM call so that they don't interfere
  • On GSM call disable User's voice – Mute PTT audio during a GSM call so that it doesn't interfere
  • Volume level — Lets you override the system's maximum volume and make sounds louder than normal; it can be useful in noisy environments
  • Play PTT start tone – Play a tone before outputting voice over PTT
  • Play PTT release tone – Play a tone when another speaker releases PTT button
  • Wait for PTT start tone – Start voice transmission only after PTT notification tone is played. If disabled, voice transmission is started immediately after tapping PTT button.
  • Event Sound Volume – Set the volume for event sounds
  • Show waveforms on main PTT screen – Use waveform visualization on the main PTT screen when you talk in the channel; turn off this animation if you prefer a blank PTT button
For details about the availability of these features, see Voice communication.

Text-to-speech settings

This setting is available only if the text-to-speech feature is enabled for your user account by the administrator. The feature ensures that channel and user names are pronounced; this is useful for devices without screens.

Parameter Description
TTS settings Change the text-to-speech language
