• PTT cannot be used while the device is performing a compliance operation, such as a bump test, calibration, or pump block test.
• Only one device can transmit on a single channel at a time. Users must take turns sending messages.
• PTT cannot be used to transmit messages when tuned to Receive Only. See Changing the PTT Channel.

• PTT on G8 can only communicate with other G8 devices.
