User Guide of SeaTalkie

Firstly, plase see this youtube for the quick user guide



Secondly, plase see this youtube for the maintainance

Thirdly, read the important note below:

Attention about battery:

SeaTalkie has a rechargeable lithium battery. We suggest to recharge the battery after you use it every time. 
If you don't use SeaTalkie for a long period. Please recharge the battery once a month. This is because too low electricity will damage the battery.

Using tips:

      1. Hold the PTT for 1 second before speak out, because the other SeaTalkies need a little bit time pick up your signals.
      2. Speak slowly and clearly.
      3. Slogans are suggested for clearly communication. That means your team should know what you say even in weak signals
      4. To get better performence: wear the SeaTalkie near the right shoulder or helmet. Equip it with the Chest Strap, Vest Mount or Helmet Mount.
      5. Plug in earphones if you need clearer voice.

About the Feedback Noise:

There is feedback noise if 2 or more SeaTalkies are speaking too close (5 meters or less).
This happens at mobiles phones too if 2 mobile phones are talking too close with both speakers are enabled loudly.


After using at sea, immerse SeaTalkie into clear water for 10 mins. Then shake it and wash it. This can help to dissolve and clear the salts inside.



Or you can communicate with higher power walkie talkie to enhance the range
