Operating Instructions

1. Push-to-Talk (PTT) Communication

The GT5 utilizes a Push-to-Talk system for instant communication over the 4G LTE network. This allows for unlimited range communication across cities, regions, and multiple locations.

  • To transmit: Press and hold the PTT button (located on the side or front of the device, or on the finger PTT accessory). Speak clearly into the microphone.
  • To receive: Release the PTT button. The device will automatically receive incoming transmissions.

2. VOX Hands-Free Calling

The Voice Operated Exchange (VOX) function allows for hands-free communication. When VOX is enabled, the device automatically transmits when it detects your voice, eliminating the need to press the PTT button.

  • To enable/disable VOX: Refer to the device's menu settings or the dedicated VOX switch if available (see device overview image).
  • Adjust VOX sensitivity: If available, adjust the VOX sensitivity in the settings to prevent accidental transmissions or missed voice activations.
