2.5 CT-Wireless-PTT (option)
This transmit button is a radio key to transmit PTT commands to a connected radio device. The CT-
Wireless-PTT and the wire-bound PTT transmit button (see chapter 2.4) have equality of function. The
CT-Wireless-PTT must be subscribed to the wire-bound transmit button. A battery provides power to
the CT-Wireless-PTT. For safety reasons, keying of the CT-Wireless-PTT is limited to 30 seconds.
