communication distance is shorter and battery life is longer. You can set a power level for each channel.
Squelch Level
You can set the squelch level of the radio to any of 0 to 9. The higher the squelch level is, the more noise
interference there will be and the harder to receive weak signals.
Alert Tone
You can enable or disable various alert tones via the PC Tool.
Microphone Gain

Note:
To avoid speech distortion, do not set a too high gain.

You can enable this mode to enable the radio to automatically enter power-saving mode if it has not

Speech Encryption
You can enable/disable speech encryption for the current channel, so that speech is sent after encryption.
