7.14 CT-Wireless-PTT (optional)
For interference-free operation of the CT-Wireless-PTT receiver in the CT-Multi
PTT Bluetooth, take care that the CT-Multi PTT Bluetooth is not located in close
proximity to the transmitting antenna of a radio or cellular phone. Heterodyning the
CT-Wireless-PTT radio signal by the comparatively strong transmit signal of a
radio or cellular phone can compromise the sensitivity of the CT-Wireless-PTT
receiver in the near field of the transmit antenna. This could interrupt the radio
transmission from the sending to the receiving PTT.
The CT-Wireless-PTT and the Bluetooth key of the CT-Multi PTT Bluetooth have equal function. The
CT-Wireless-PTT necessarily requires subscription to the CT-Multi PTT Bluetooth. A battery supplies
electric power to the CT-Wireless-PTT. For safety reasons, continuous keying of the CT-Wireless-PTT
is limited to 30 seconds.
