Transmitting and Receiving
• The Terrain 850 transmission is "one way-at-a-time." While you are speaking, you cannot receive a
transmission.
• The Terrain 850 is an open-license band. Always identify yourself when transmitting on the same channel.
Receiving (listening to speech)
The unit is continuously in receive mode when the unit is turned ON and not transmitting. When a signal is received on the
current channel, the "RX" icon is displayed on the LCD screen.
Transmitting (sending speech)
• Press and hold the PTT (push to talk) button to transmit your voice. The "TX" icon is displayed on the LCD
screen.
• Hold the unit with the MIC (microphone) about 5 cm away from your mouth. While pressing the PTT button,
speak into the MIC (microphone) in a normal tone of voice.
• Release the PTT button when you want to finish transmitting.
Monitor
You can use the monitor feature to check for weak signals on the current channel.
• Press and hold the MENU and DOWN buttons at the same time. The "RX" icon is displayed on the LCD
screen. Your Terrain 850 will pick up signals on the current channel, including background noise.

Setting the VOX (Voice Activated) Sensitivity
In VOX mode, the Terrain 850 will transmit a signal only when it is activated by your voice or other sounds around you. The
unit will transmit for a further 2 seconds after you stop talking.
The level of VOX sensitivity is shown by a number on the LCD screen. At the highest level, the units will pick up softer
noise (including background noise); at the lowest level, it will pick up only quite loud noise.
• Press the MENU button 4 times, the "VOX" icon is displayed and "OF" flashes on the LCD screen.
• Press the UP button to set the VOX sensitivity up to the maximum level (the maximum level is "3".)
To deactivate the VOX function, press the DOWN button until "OF" appears on the LCD screen.
• Press the PTT button to confirm your setting. "VOX" will remain on the LCD screen when the VOX feature
is activated.
VOX operation is not recommended if the Terrain 850 will be used in a noisy or windy environment.
