3.3.2. Transmit Mode
If /PTT input is active (PTT=Push To Talk key is pressed) the transceiver switches to transmit mode.
Microphone(s) signals can modulate the transmitter.
• PTT 1 input activates transmission from microphone path 1
• PTT 2 input activates transmission from microphone path 2
• If BOTH MIKES are active / enabled in the installation setup, each input (PTT 1 or 2)
activates the transmission from both microphone paths simultaneously.
The "TX" symbol in the left upper corner of the display indicates the device is in transmit mode.

In transmit mode several user actions such as changing frequency selection mode or channel spacing
mode, which are normally allowed in receive mode, are blocked. (As an exception in standard mode
the "Preset" frequency may still be changeable, even during transmission).
No intercom operation is possible in transmit mode.
The sidetone (demodulated audio of the emitted signal) is available on the headphone output. The
transmit mode automatically deactivates the speaker.
Note: Transmit mode is automatically terminated (return to receive mode) after
120 seconds of continuous transmitting even if PTT is still pressed. In this case
"STUCK PTT" is indicated (refer to page 40). For initiation of a new
transmission, /PTT line needs first to become inactive.

Frequency Selection Modes
Following frequency selection modes are available on AR620X and RCU6201:
• Standard mode
• Direct tune mode
• Channel mode
• Scan mode
The "Standard Mode", "Direct Tune Mode" and "Channel Mode" provide different user interfaces for
convenient selection of the operating frequency. These three frequency selection modes are
selectable by consecutive short pressing of "MDE" key. They appear in the following order: "Standard
Mode", "Direct Tune Mode" "Channel Mode", "Standard Mode", and so on. When toggling between the
three modes the active frequency always remains the same and active.
"SCAN Mode" is a sub-mode of standard mode and used for monitoring two frequencies at the same
time. A 2 seconds press on "↕/SCN" key activates/deactivates the scan function.
The availability of the modes depends on enabling or disabling in the "Configuration Settings".
