4.3.3 VOX – Voice Activated Transmission
The TSX300 may be set to VOX mode so that transmission can be
activated by voice audio either through the internal or an external
microphone. The radio has 3 VOX sensitivity settings to adjust
the voice volume needed for transmission activation. The default
setting is VOX OFF.
- To access the VOX Mode Menu from the Main Screen, Press the
MENU button (Softkey #2), use the UP/DOWN (p/q) button
to scroll and highlight VOX as shown in Figure 48. Press OK
(Softkey #1) to enter the VOX Menu as shown in Figure 49a.
- To activate VOX mode, select 1 of the 3 sensitivity levels using the
UP/DOWN (p/q) button to scroll through the choices shown in
Figures 49a and 49b. NOTE: Level 3 is the most sensitive (used
when background noise is minimal), and Level 1 is least sensitive
(used when background noise is present).
- Once you have selected your choice by highlighting it, press the
OK button (Softkey #1) to activate the VOX function. To exit with-
out activating VOX, press the EXIT button (Softkey #2) to return to
the Main screen.
- If VOX is active, the VOX icon will be shown on the LCD display
on the Main screen as in Figure 50.
NOTE: If you turn the power off while in the VOX mode, VOX
mode will be cancelled. The next time you turn on the radio, it will
be in the normal PTT communications mode.
VOX TIP: When the VOX mode is active, radio receivers may
miss the beginning of a communication because it takes the voice
audio longer to activate the transmitter. Experienced radio users
will draw out their rst word or repeat it to allow the receiver
to hear the entire communications. Use of VOX mode may take
some practice to get familiar with its operation.
