TRANSMISSION VOX (VOICE-OPERATED TRANSMISSION) VOX eliminates the necessity of manually switching to the transmission mode each time you want to transmit. The transceiver automatically switches to transmission mode when VOX senses that you have begun speaking into the microphone. When using VOX, develop the habit of pausing between thoughts to allow the transceiver to drop back to reception mode briefly. You will then hear if anybody wants to interrupt, plus you will have a short period to gather your thoughts before speaking again. Your listeners will appreciate your consideration as well as respect your more articulate conversation. Press [VOX (LEV)] to toggle between VOX ON and OFF. • " " appears when the VOX function is ON. ■ Microphone Input Level To enjoy the VOX function, take the time to properly adjust the VOX gain. This level controls the capability of VOX to detect the presence or absence of your voice. In CW mode, this level cannot be adjusted. 1 Select USB, LSB, FM, or AM mode. 2 Press [VOX (LEV)] to switch the VOX function ON. • " " appears. 3 Press and hold [VOX (LEV)]. • The current VOX gain level appears on the sub-display. 4 While speaking into the microphone using your normal tone of voice, adjust the setting (default is 4) using the MULTI/CH control until the transceiver reliably switches to transmission mode each time you speak. • The selectable gain range is from 0 to 9. • The setting should not allow background noise to switch the transceiver to transmit mode. Note: The VOX gain level can be adjusted even if VOX is switched OFF or while you are transmitting. COMMUNICATING AIDS 7 ■ Delay Time If the transceiver returns to reception mode too quickly after you stop speaking, your final word may not be transmitted. To avoid this, select an appropriate delay time that allows all of your words to be transmitted without an overly long delay after you stop speaking. 1 Select USB, LSB, FM, or AM mode. 2 Press [VOX (LEV)] to switch the VOX function ON. • " " appears. 3 Press and hold [KEY (DELAY)]. • The current setting appears on the sub-display. The default is 50 (1500 ms). 4 While speaking into the microphone using your normal tone of voice, turn the MULTI/CH control such that the transceiver switches to reception mode after you have stopped talking. • The selectable range is from 5 to 100 (150 ms to 3000 ms) in steps of 5, or OFF. 5 Press [CLR] to store the parameter and exit the setting mode. ■ Anti-VOX Adjustment The TS-590SG transceiver has a DSP IC to improve and customize incoming/ outgoing audio signals. When the VOX function is turned ON, the DSP IC adjusts the Anti-VOX level automatically, comparing the reception sound level and microphone input level. So, you never have to worry about adjusting the anti-VOX level. Note: When connecting a headphone to the Phone jack, Anti-VOX will not function. ■ Data VOX Although the microphone is normally used for VOX transmission, you can also utilize the audio input of the ACC2 or USB connector. When the transceiver detects an audio signal on the ACC2 or USB connector, it automatically transmits. You can select ACC2 or USB via Menu No. 69 ("Selecting a Data Transmission Line") {page 62}. 1 Select USB, LSB, FM, or AM mode. 2 Press [MENU], then press [Q-M.IN]/ [Q-MR] or turn the MULTI/CH control to select Menu No. 76. 3 Press [M.IN] to set the VOX with DATA input function ON. 4 If necessary, adjust the VOX gain level for the ACC2 or USB connector {page 32}. Note: While VOX with DATA input is set to ON (Menu No. 76), speaking into the microphone also activates the VOX function and you can still transmit using Mic [PTT]. Anti-VOX does not function with Data VOX. While the Data VOX function remains ON and the transceiver is connected to a sound source, such as a PC, the transceiver may begin transmitting due to the sounds emitted from the sound source. To avoid unintended transmission while the transceiver is connected to the sound source, turn the Data VOX function OFF. 31
