Interference Cancellation Function (CTCSS)
The interference cancellation code can minimize the interference of the same channel, providing you with multiple choices of combinations. For the specific method, please refer to the second point of the “Settings menu” for operation settings. This process can be repeated to set a different combination for each channel.

When a channel is set with the group code (CTCSS) function, other calls with different group codes on the same channel can be fooled.

TOT (Time Out Timer)
The function of the timeout timer is to prevent the channel from being occupied for a long time, and to avoid the continuous transmission time of the walkie-talkie being too long and causing the fuselage to heat up. The TOT limit time is hereby set. In use, when the continuous signal transmission time exceeds 180s, it will be considered a transmission timeout, and the walkie- talkie will automatically stop transmitting at this time, in order to release the occupied channel and avoid the fuselage heating. At this time, just release the [PTT] key and press the [PTT] key again to resume transmission.

Set & Send Call Ringtone Function
You can set your favorite Call tone on the intercom for the members of the group so that the members can recognize your call easily. For specific methods, please follow point 4 of the “Settings Menu”.

VOX Hand-Free Function
After the VOX function is turned on, you don’ t need to press the [PTT] key during intercom to achieve continuous intercom with group members, which is similar to the hands-free function of a mobile phone. For specific methods, please follow the 4th point of “Settings Menu”.

** Notice!**
After the VOX function is turned on, because the product is in the transmitting and receiving state for a long time, the power consumption of the machine will increase greatly, thereby shortening the battery life of the product. It is recom-mended to use it with caution.

Tip: Long press the key to scan in the opposite direction.

Notice!
Before scanning, be sure to close (OF) the group code (CTCSS), so that any group member can be searched. If it is set to a certain CTCSS, such as 02, then only group 02 can be searched, and other members will not be able to search.
