Remote Kill/Stun/Revive
TH-8800 provides enhanced security to stop unauthorized users by remote inhibition of either transmission or both transmission and reception. The inhibited radios will return to normal operation when receiving a revive signal.
4 Types of Safety Protection
TH-8800 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): A pre-defined emergency procedure will be activated if the radio is horizontally or inversely positioned in a certain period of time when the man down function is on. To cancel the alert, user has to place the radio vertically.
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.
7 Signaling
CTCSS/CDCSS, DTMF, 2-Tone, 5-Tone, QDC1200, QDC2400 (Optional) 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. And QDC1200 is compatible with MDC1200 signaling.
PTT ID Encode/Decode
TH-8800 provides identification of radio to control center or partners through this function. It simplifies the way of communication and management.
25.0 kHz/20 kHz/ 12.5 kHz Switch
TH-8800 has different channel spacing 25.0 kHz/20 kHz/12.5 kHz, which 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 Announcement
This function enables the radio to announce the current channel. It is useful to users working in dark environment.
VOX
