9 (most sensitive).
¥ To turn OFF the VOX function, select ÒOFFÓ in step 2.
Note:
uWhile in Menu Mode {page 24}, the VOX function is temporarily
disabled.
uSince the VOX circuit must detect the presence of your voice, you
may notice a slight delay in transmission; the very first part of
your message may not be transmitted....

 ¥ If the transmission does not begin, you must
readjust the VOX Gain so that transeiver
transmits while you are speaking.  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...

VOX Delay Time
If the transceiver returns to Reception Mode too quickly
after you stop speaking, the end of your transmission
may not be sent.  To avoid this, select an appropriate
delay time that allows your entire transmission to be
sent, before Transmission Mode ends.  However, do not
make the delay overly long.
1Press [MENU].
2Turn the Tuning control to select Menu No. 22 (VD).
3Press [MENU].
4Turn the Tuning control to select the desired delay
time from 250, 500 (default), 750, 1000, 1500, 2000...

VOX on Busy
You can configure the transceiver to force VOX
transmission even if the transceiver is receiving a
signal.
1Press [MENU].
2Turn the Tuning control to select Menu No. 21
(VXB).
3Press [MENU].
4Turn the Tuning control to select ÒONÓ.
¥ To suppress the VOX transmission when the
transceiver is receiving a signal, select ÒOFFÓ.
5Press [MENU] to store the setting or [PTT] to cancel.
Note:  You can press [PTT] or [CALL] (if 1750 Hz is programmed) totransmit, regardless of Menu No. 21 (VXB)...

INTERFACING TO PERIPHERALS
SP/MIC JACK
The SP/MIC jack on the transceiver can be configured
to interface to various kind of peripherals available for
the transceiver, such as a speaker microphone
(SMC-32/ 33/ 34) and PC interface cable (PG-4Y).
Access Menu No. 31 (PC) and select ÒONÓ or ÒOFFÓ.
SP/MIC
If you plug the speaker microphone or headset into the
SP/MIC jack, access Menu No. 31 and select ÒOFFÓ
(default).  To emulate the programmable function keys
using external keys (to control the...

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...

nUsing the PG-4Y PC Interface Cable
Use the PG-4Y PC interface cable to connect
between the transceiver and PC.  Plug the Speaker/
Microphone connector to the SP/MIC jack and DB-9
connector to one of the COM (serial) ports on your
PC.
