How do you use Cobra Walkie Talkie?

Cobra radio does not need any licence as it is Licence Free radio. If you press PTT (Push-To-Talk) button, and you hear beep-beep, it is probably signal for LOW BATTERY LEVEL.

You need to charge the battery before using it. If this does not help, either battery needs replacing or radio is faulty. Make sure both radiOS are on the same channel and sub-channel (Sub-audiable tone), otherwise you will not be able to communicate with the other radio user. More details will be in your Operation Manual, if you have mislaid it then you will be able to order another one from your supplier or Cobra themselves.
