Three alarm methods: active alarm, passive alarm, and automatic alarm. Active alarm: Press the emergency call button to emit a piercing alarm sound, providing users with immediate rescue alert notifications (sending their identity number or background sound to companions or the system), meeting the requirements for emergency communication.
* Silent Inquiry
When there is a need to know whether a two-way radio is within the communication range, a silent inquiry code can be sent within the communication area. If the two-way radio is within the area, it will automatically reply with a code.
* Multi-level Password Protection
Up to three types of password protection: read frequency password, write frequency password, and embedded information password, ensuring the information security of the two-way radio.
* Voice Companding
a) Voice compression and low-level expansion technology achieve clearer, more distinct, and more powerful voice quality, ensuring smooth communication even in noisy environments. b) Whisper function
c) When this function is enabled, even speaking very softly can be heard clearly by the other party, suitable for private conversations.
* Battery Level Query
After setting this function, simply press a key, and the two-way radio will indicate the current battery level through prompt tones "1", "2", "3", "4", representing "low battery", "not full", "almost full", and "full" statuses, respectively.
* VOX Voice Control Function
Enable the VOX voice control function to automatically activate PTT transmission through voice without pressing the PTT key, freeing both hands for operation. It works even better when used with **.
* Voice Scrambling
Built-in scrambling ** ensures the privacy of conversations between two parties, preventing other two-way radios on the same frequency from intercepting information.
* Special Features
* FLASH IC Function
* Users can flexibly record custom voice announcements and various voice broadcast functions according to their preferences. It also supports storing up to 7,000 GPS points.
* GPS Function (Optional) Built-in GPS module enables GPS positioning and location information broadcasting for the two-way radio. When used with Kelixun's GIS system, it enables more GPS function applications.

* Authorized Transmission After setting the authorization function, the two-way radio can only transmit after obtaining authorization, suitable for occasions where transmission capacity needs to be controlled.
* Low Volume Function After enabling this function, even if the volume knob is accidentally turned down, the other party's call can still be heard, avoiding missing important calls due to accidentally lowering the volume.
