Using the NT3
1. Plug the throat mic into the PTT/VOX splitter (E) using the mini
DIN connectors (D). Be sure to align the indicators when
connecting the mini DIN.
2. Plug the 3.5mm pin of the adaptor wire for your radio or phone
into the PTT/VOX splitter. If you would like to use a PTT, plug into
adaptor into jack (H) and the PTT into the PTT jack (J). If you will
be using the VOX function on your radio or phone, plug into adap-
tor jack (I). Plug the other end of the adaptor into your radio or
phone.
3. Pace the neck band around your neck. Position the transponder
(A) so that it sits flush to your neck. Due to variances in human
anatomy, the position of the transponder may require adjustment
for maximum performance.
4. Your throat mic is now operational.
Using the PTT and VOX
The NT3’s default transmission mode is VOX. To use VOX mode,
make sure your VOX-enabled radio or phone is set to VOX. Simply
start speaking to activate transmission.
All versions of the NT3 (except adaptors for mobile phones and PC)
can be used with any of IASUS Concepts’ original PTT switches. The
splitter also has a PTT button. To transmit, simply press the button
on the splitter or PTT and talk. To receive, release the button.
USE and Care
For best transmission quality when using the NT3, place the
transponder about 0.5 - 1 inch on either side of your larynx/voice
box. Optimal transponder position on the neck will vary between
individuals.
The NT3’s neck strap is adjustable. To increase the diameter of the
strap, simply adjust the neckband at the clips. Reverse the
direction to decrease the diameter.
While the NT3 is highly water resistant, it is not waterproof. Do not
immerse it in water.
The transponder is highly sensitive. Do not apply pressure to the
inside face of the transponder.
Caution
Do not operate your device at high volume levels when using the NT3. Hearing
experts advise against continuous exposure to high volume levels. If you
experience ringing in your ears, discontinue using the NT3. If using the NT3 in
a noisy environment, we strongly recommend using a single earplug in the ear
opposite the earpiece to safeguard your hearing.
