What must you do after selecting a desired channel on the TPT?

After selecting a desired channel on the Tactical Portable Transceiver (TPT), it is necessary to finalize the selection. This step ensures that the chosen channel is active and ready for communication. Finalizing the selection typically involves confirming the channel setting, which may include pressing a button to lock in your choice or otherwise affirming the selection. It is an essential part of the operation as it prevents accidental changes and allows for effective use of the device during missions.

Adjusting the volume, resetting the device, or pressing a sequence button might be important steps in the overall operation of the TPT but do not directly follow the channel selection process as a required action. Finalizing the channel ensures proper communication protocols are followed, which is critical in operational settings.
