Using Your GP3/GP3-X2
1. Peel the “loop” side of the Velcro patches off from each
speaker and remove the white backing.
2. Attach the loop Velcro patches to the interior of your helmet,
aligned at ear level.
3. Affix the padded speakers to the helmet by matching up the
Velcro pieces. Make sure with the longer cable is on the left.
4. Plug the helmet speaker earphones into the DIN jack on the
throat strap. Next, plug the throat mic into the PTT/VOX splitter
using the mini DIN connectors. Be sure to align the indicators
when connecting the mini DIN.
5. 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
PTT jack. If you will be using the VOX function on your radio or
phone, plug into VOX jack. Plug the other side of the adaptor into
your radio or phone.
6. Lastly, place the neck band around your neck. Position the
transponder 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.
7. Your throat mic is now operational.
Using the PTT
All versions of the GP3 and GP3-X2 (except adaptors D and E)
come with the Finger PTT. To use, simply plug the PTT into the
PTT/VOX splitter. To transmit, simply press the button and hold
while talking. To receive, release the button. In mobile phone
versions, the Finger PTT functions as an answer/end call button.
Simply push to answer the call, and push again to hang up.
USE and Care
For best transmission quality when using the GP3/GP3-X2, 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 GP3/GP3-X2’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 GP3/GP3-X2 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
It is extremely dangerous to ride a motorcycle while talking. It may also be
illegal in some areas. Please only use the GP3/GP3-X2 in areas where it is
permitted. Use caution when operating.
Do not operate your radio or phone at high volume levels when using the
GP3/GP3-X2. Hearing experts advise against continuous exposure to high
volume levels. If you experience ringing in your ears, discontinue using the
GP3/GP3-X2.
