COMMUNICATING AIDS 5 Transmission in Data Mode RIT/XIT Transmission via PTT Switch, SS Terminal and SEND Switch transmission by making use of the [PTT] switch on the microphone, SS terminal of the REMOTE connector and [SEND] on the front panel. Under normal circumstances, the microphone audio is transmitted via this operation. • This transceiver continues to transmit signals while [PTT] on the microphone is pressed and held down. • This transceiver transmits signals when the SS terminal of the REMOTE connector is short-circuited to GND. • Pressing [SEND] each time toggles between transmission and reception. Transmission via DATA PTT or DATA SEND DATA PTT (PKS terminal of ACC 2 connector) or the PF key that is assigned with "DATA SEND" is used to switch between transmission and reception. For more details, please refer to "PF Keys (Programmable Function Keys)" (16-2). This function comes in handy when transmitting audio or data from an external device. This operation transmits normal audio signals or audio signals that are input to the ANI terminal of the ACC 2 connector. A different audio path can be specified. For more details, please refer to "Configuration of the Input Path of TX Audio" (8-1). • This transceiver continues to transmit signals while DATA PTT (PKS terminal of the ACC 2 connector) is short-circuited to GND. • Pressing the PF key that is assigned with "DATA SEND" toggles between transmission and reception. RIT (Receiver Incremental Tuning) RIT is a function for fine-tuning only the RX frequency in 10 Hz steps within the ±9.99 kHz range without altering the TX frequency. This is used such as when the TX frequency of the station that this transceiver is communicating with has become slightly deviated. • When the FINE mode is ON, the offset frequency of RIT switches to a step size of 1 Hz. RIT functions in the same way in all modes as well as when VFO or the memory channel mode is in use. 1 Press [RIT]. The [RIT] LED lights up and the RIT offset frequency is displayed. 2 Turn the [RIT/XIT] control. Fine-tune the RX frequency for RIT. • To clear the offset frequency for RIT, press [CL]. The RIT offset frequency value is reset to 0. 3 Press [RIT] to end the process. RIT is turned off. The RX frequency is restored to the value prior to performing step 1. RIT Shift This is a function for setting the frequency adjusted with RIT to a RX band. Press and hold [RIT]. The RX frequency that is adjusted using RIT is set to an RX band. The RIT frequency is then cleared and the RIT function is turned off. XIT (Transmitter Incremental Tuning) XIT is a function that can be used to fine-tune the TX frequency in 10 Hz steps within the ±9.99 kHz range without altering the RX frequency. • When the FINE mode is ON, the offset frequency of XIT switches to a step size of 1 Hz. 1 Press [XIT]. The [XIT] LED lights up and the XIT offset frequency is displayed. 2 Turn the [RIT/XIT] control. Fine-tune the TX frequency for XIT. • To clear the offset frequency for XIT, press [CL]. The XIT offset frequency value is reset to 0. 3 Press [XIT] to end the process. XIT is turned off. The TX frequency is restored to the value prior to performing step 1. XIT Shift This is a function for shifting from operation using XIT to the split mode at one touch. Press and hold [XIT]. When the TX frequency that is adjusted using XIT is set to a TX band, the operation switches to the split mode at the same time. The XIT frequency is then cleared and the XIT function is turned off. ● If the frequency is changed in the entry mode, the RIT/XIT function is automatically turned off. 5-7
