The device has an operating voltage battery capacity with a long battery life of up to 14 hours for analog mode and 18 hours for digital mode. It also features intermodulation, spurious rejection, blocking, and desensitization with high levels of accuracy and reliability.
The device is designed with environmental specifications of -20 ~ +60 operating temperature, ESD protection, dust, and water resistance with an IP68 rating. It also supports basic software encryption, optional high-level software encryption, or TF card hardware encryption. The device is also equipped with GPS technology for location services.
Product Usage Instructions
Before using the device, make sure to fully charge the battery by attaching the device to the charger provided in the package. Insert the battery into the battery slot located at the back of the device and attach the antenna. Turn on the device by pressing and holding the power button until the device vibrates.
To use the device, select the desired channel by using the navigation buttons on the front panel. You can adjust the volume level by using the volume control button located on the side of the device. The device also features AMBE++Vocoder for voice encoding and decoding.
The device supports VOX and Man Down features. The VOX feature allows you to use voice activation to transmit without pressing the PTT button. The Man Down feature automatically sends an emergency signal to the control center when the device detects a fall or a lack of movement for a certain period. The device also features GPS location services. To use this feature, make sure that the GPS function is enabled in the device settings. The device will then provide location information to the control center.
When you are finished using the device, turn it off by pressing and holding the power button until the device vibrates. Remove the battery from the battery slot and store the device in a safe and dry place.
