FAQ
Q: Why sometimes your partner's voice is intermittent?
A: Please note that you are within normal communication range, If you want use radio in distance range, please change other antenna with a bigger output power.If still same problem, please send the radio back to your authorized dealer repair.

A: Please check the battery contacts on the walkie talkie. If it is broken or twisted, please return the radio to your authorized dealer for maintenance during warranty.
Q: Can't transmit or receiver signal with other members?
A: First, please verify that the channel frequency and the CTCSS, you are used the same as those of your group members. Please make sure that you and your partners are all within the radio coverage, If the channel frequency and the CTCSS are the same.
Q: Why sometimes received voice from other groups?
A: Two way solutions.You can change another channel or change another channel frequency by PC software.
Q: Which is better -VHF or UHF?
A: epends on the terrain. The UHF signal is attenuated or absorbed by foliage, rough terrain and trees, VHF does better outdoors. The VHF has difficulties penetrating steel and concrete, UHF does better in and around buildings. If you use the radios in both environments, we prefer using UHF band.
