These are the current default controls. Your saved FiveM bindings can override them. For the first power-on and channel selection, start with Radio basics.

​
Default keys

Channel and zone shortcuts step through your permitted selections. A zone change selects the first available channel in that zone, so check the channel afterward. PTT needs a powered, available radio, a permitted transmit channel, coverage, and a confirmed channel affiliation. If you hear a busy or denial tone, release PTT rather than holding it indefinitely.
F5 opens the controls; it does not power on the radio. Closing the interface does not turn the radio off. Use PWR or the unit-specific power buttons in settings.

​
Chat commands

Enter these in chat, including the leading slash. The old /radio command is retired and does not open the radio. Use /lsrradio instead. For TMS addressing, use a clear name such as 2L20 - Alex; the recipient callsign is 2L20. Your display name changes after it is accepted, not merely when you type it. See Emergency and messages before using emergency controls.

​
On-screen controls

Open the radio to use its buttons and softkeys. Softkey labels change with the current screen and can be customized in settings.
  • PWR toggles power for the displayed handheld or mobile unit.
  • Zone opens your available zones; select the one you need.
  • Chan opens the channel list; select a channel to tune it.
  • Menu, or the radio’s center/OK control from home, opens the in-radio settings menu.
  • The on-screen side PTT works while held; release it to stop transmitting.
  • EMER supports a press to activate and a separate owner hold to clear.
  • In Chan, Scan+ and Scan- change the highlighted channel’s scan membership.
  • An assigned home-screen Scan softkey changes the selected channel’s membership, not scanning mode.
Use the radio’s navigation controls to move through lists and confirm selections. You can also click list entries. Focus the radio menu to use Up, Down, and Enter with the list. Use Escape or the settings close button to leave the full settings panel. In layout editing, Escape, Home, or Enter finishes the edit.

​
Remap keys safely

  1. Open the pause menu, then Settings, Key Bindings, and the FiveM section.
  2. Find the entries beginning LSR Radio:.
  3. Change Toggle radio or Push to talk, or assign the unbound emergency and display-switch actions.
  4. Check both primary and secondary bindings for duplicate or conflicting keys.
  5. Close the pause menu, chat, and settings. Test the new key in normal gameplay, pressing and releasing it once.
Saved bindings take precedence over defaults; a changed default does not necessarily replace your existing choice. Handheld and mobile displays share the same toggle-radio binding. The keybinding entry for emergency may mention a duration; use the server’s configured hold requirement rather than treating that label as authoritative.
Do not clear all bindings or blanket-unbind F5 to fix one radio action. That can remove controls belonging to other features. Remove only the stale binding you have identified.
If an old key still acts, inspect both primary and secondary LSR entries and any old manual bindings. Remove an identified stale entry through FiveM settings where possible. If an old manual entry persists outside that menu, close FiveM and back up your personal binding configuration before removing only that entry. Ask for help if you cannot confidently identify it; do not delete the whole configuration.

​
When a control seems unresponsive

Typing in TMS suppresses PTT and channel/zone shortcuts so typing cannot accidentally transmit or retune. Channel/zone shortcuts are also blocked while settings, the pause menu, or a text-entry dialog captures input. Finish or leave that screen, then test again. Release PTT before opening other menus or switching applications. In a vehicle, an off mobile face does not mean your powered handheld has stopped working; /radiodisplay changes only the face.
