VOX Gain
To enjoy the VOX function, take the time to properly
adjust the VOX Gain level. This level controls the VOX
circuit to detect the presence or absence of your voice.
There are 2 ways to adjust the VOX Gain.
While the VOX function is ON:
1Continue from step 1 and 2, above.
Press [MENU] to turn the VOX function ON, then
press any key other than [LAMP], [MONI/SQL] and
[MENU] to exit Menu Mode.
2Speak into the headset microphone using your
normal tone of voice to transmit.

To readjust the gain, press and hold [PTT] then turn the Tuning control to select a more sensitive gain level. ¥ While readjusting the gain, you can release [PTT]. The transceiver will remain in Adjustment Mode for approximately 5 seconds. 3Adjust the VOX Gain by turning the Tuning control until the transceiver reliably switches to transmission mode each time you speak while the transceiver is transmitting. From the Menu: 1Continue from step 1 and 2 from VOX (Voice- Operated Trasmission) on page 97. 2Press [MENU] to store the VOX Gain level. ¥ÒVOXÓ appears on the bottom right of the display when the VOX function is ON. 3Press any key other than [LAMP], [MONI/SQL] and [MENU] to exit Menu Mode. 4Adjust the VOX Gain, performing steps 1 to 3 until the transceiver reliably switches between transmission and reception each time you speak. ¥ The setting should not allow background noise to switch the transceiver to Transmission Mode.

5Press [MENU] to store the setting or [PTT] to cancel.
6While speaking into the microphone using your
normal tone of voice, adjust the VOX delay time,
performing steps 1 to 5 until the transceiver reliably
switches between transmission and reception each
time you speak.
Note:
uIf you press [PTT] while the VOX function is ON, the VOX Delay
Time is not reflected to the transmission.
uIf you press [CALL] (if 1750 Hz is programmed) {page 35} to
transmit a 1750 Hz tone, the VOX Delay Time is not reflected.
uIf the DCS function {page 73} is ON, the transceiver remains in
Transmission Mode for the duration set by the VOX Delay Time. It
then sends a Turn-Off Code to close the receiving partyÕs squelch.

Note 1: Voltage is developed across a 100W resistor on the 5 V line in
the transceiver. When 2 mA flows, approximately 4.8 V is developed.
Note 2: A 10 mF capacitor is not required in the following cases:
¥ When other equipment has DC blocking capacitors.
¥ When a 2-terminal electret condenser microphone is used.
PC
To connect the transceiver to a PC in order to manage
the memory channels in the transceiver, use the PG-4Y
PC interface cable. You will also need the supported
software to manage the memory channel contents of the
transceiver. To download the software, access the
following URL:
http://www.kenwood.com/i/products/info/amateur.htm.
To use the software, access Menu No. 31 and select
ÒONÓ {page 107}.
For your reference, the following diagram shows how
the transceiver communicates to the PC using a serial
