Tips: Etiquette for using wireless walkie-talkies

The 22 channels of your wireless walkie-talkie are shared

with others and used in turn. Other groups may be using

certain channels. In order to not disturb other people's calls,

and have better call quality yourself, please don't use the

channel that others are using.

Try to change the channel to prevent channel blocking or

use the【LAMP】key to check the channel activity. If you

hear quiet noise after pressing the【LAMP】 key, it means

that the channel is free, and you can use it.

2. Communication (transmitting and receiving)

When using wireless walkie-talkies to talk to each other, the

walkie-talkies of the same group must be set to the same

channel and interference cancellation mute code (0 to 99).
