|
voice control
Automatic control of sound transmission function, can be carried out by launching the operation, without the need to manually press the PTT key launch.
|
|
Launch timing function
This function is to prevent any caller occupied the channel time is too long, the timer to limit the number of times each time to launch the walkie talkie, limiting the user timeout launch.
|
|
Busy channel lock
This machine can store up to 16 channels. The rotating channel switch selects the channel, counter clockwise to decrease the value of the channel, and rotates clockwise to increase the channel value. If the rotation to the empty channel without any information, a "beep" sound space frequency tone alert.
|
|
Automatic power saving function
When the channel is idle or does not carry out any operation (12 seconds), the battery energy saving function is automatically turned on, and the walkie talkie starts to switch the receiving circuit alternately at a certain time, which has achieved the purpose of automatic power saving and energy saving. The time ratio of the switch circuit can be set by programming software.
|
|
computer programming
The data can be connected with the computer through the data line to the interphone frequency data, the function parameter and the signal and so on carries on the programming.
|
|
flashlight lighting
Practical flashlight function, to solve the emergency needs in the dark environment.
