Kill/Stun/Revive
TH-8000 provides enhanced security to prevent unauthorized use of lost or rented units by remote inhibition of either transmission or both transmission and reception. The inhibited radios will return to normal operation after receiving a revive signal.
4 Types of Safety Protection
TH-8000 provides 4 types of safety protection: lone worker, safety check, emergency alert and man down (optional).
Lone Worker: This function provides security for individuals who work remotely from their members. If the user does not respond to indication tone, the pre-defined emergency procedure will be activated if pre-defined time expires.
Safety Check: If the user does not respond to safety check signal, the pre-defined emergency procedure will be activated.
Emergency Alert: Press the preset emergency key to emit emergency alarm, or secretly send ENI or background noise to pre-defined person or dispatch center.
Man Down (Optional): When this function is ON, a pre-defined emergency procedure will be activated if the radio is horizontally or inversely positioned for a certain period of time. Place the radio vertically to cancel the emergency alert.
Auto Contact
This function is helpful for situations which require close communication, such as climbing, exploration and rescuing. The radio beeps when the user is being out of communication range when this function is ON.
Voice Encryption
This function provides communication security against eavesdropping.
Whisper
This function can be enabled in quiet environment and allows you to speak quietly into the radio and still be heard clearly.
Voice Compandor
This function improves the audio quality by reducing noise and amplifying the audio if the voice is low.
Various Signaling Types
CTCSS/CDCSS, DTMF, 2 Tone, 5 Tone and QDC1200 are optional in order to adapt to different systems around the world. Individual call, group call, monitor and remote kill/stun/revive can be realized by 5 Tone / QDC1200 signaling.
PTT ID Encode
It provides identification of radio to control center or partner’s radio, which is convenient for communication and management.
25kHz/20kHz/12.5kHz Switchable
Different channel spacing 25kHz /20kHz /12.5kHz are optional to comply with the regulations of different countries.
High/Middle/Low Power Switchable
The radio can be switched among low power, middle power and high power. When talk range is small, the radio can be switched to low or middle power to save battery power.
Announce Battery Power
Press the function key and you will hear the annunciation of current battery power state.
Channel Annunciation
This function enables the radio to announce the current channel when user switches the button on, it is useful for working in dim environments.
VOX
Hands-free operation is available when VOX function is turned ON.
Embedded Information
This function allows you to write operating records such as serial number, user information, and repair information into the radio.
