3. Speak in a normal voice to ensure that the VOX circuit is
activated.
Note: When the VOX circuit is activated, you will hear a Tx
tone signal via the ear microphone and the Tx LED will light
up.
Remarks
1. The rise time of the VOX circuit is set at approximately 0.3
seconds (which is fast). But due to this 0.3-second slight delay,
the transmissions may be clipped at the beginning. To prevent
this, we recommend that you initiate each transmission by
transmitting a vowel sound like "EEE" to ensure smooth VOX
communications.
2. The PTT switch on the VOX interface remains functional even
when the system is operating in VOX mode.
3. When your voice is picked up by the VOICEDUCER earpiece and
the VOX circuit is activated, you will hear a short "BEEP"
confirming your transmission. Continue speaking after hearing
this tone. It takes about 1.3 seconds for the VOX circuit to
deactivate itself after you stop talking.
• Talking or transmitting while receiving activates the VOX,
interrupting both the transmission of outgoing signals as well
as the reception of incoming signals.
• Care must be exercised to time one's transmissions so as not
to conflict or interfere with simultaneous transmissions on the
same channel.
