Voice Prompts
This function is designed for users working in dark environment, it enables radio to report current channel when the corresponding function key is pressed.
Monitor
This feature enables user to hear weak signals. User can adjust volume by pressing MONI key when no signals are received.
Battery Power Indication
The radio will report current battery power when the corresponding function key is pressed. It also reminds users to replace or charge the battery if the battery power is low.
High/Low Power Switch
The radio can be switched between low power and high power. To save power, users can switch it to lower power mode when talk distance is short.
VOX
Hands-free operation is available when VOX function is ON.
PTT ID Encode (DTMF)
TH-2900 provides identification of radio to control center or partners through this function. It simplifies the way of communication and management.
Squelch Tail Elimination
The function will minimize the annoying audio outputs that occur at the receiver during a transmission.
Scan
This feature enables radio to scan every channel in scanning list by pressing function key to activate scanning. The user can detect the available channel of partners, and then start a communication.
Busy Channel Lockout (BCL)
BCL is used to protect the on-going conversation from unwanted interference. Users might also be blocked sometimes.
CTCSS/CDCSS
CTCSS/CDCSS encode and decode are useful to avoid unwanted conversation on the same channel.
25.0 kHz/20 kHz/ 12.5 kHz Switch
TH-2900 has different channel spacing 25.0 kHz/20 kHz/12.5 kHz, which are optional to comply with the regulations of different countries.
Wired Clone
To quickly set the parameters on a radio, users can clone the radio data from another radio with the supplied data cable, which can save the time of parameters setting.
PC Programming
Frequency and various features can be set by PC programming software.
Various Analog Signaling Types
It supports various analog signaling (DTMF, CTCSS, CDCSS), provides higher function expansion capacity.
Kill/Enable
It provides enhanced security to stop unauthorized users by disabling or enabling of either transmit or both transmit and receive. The disabled radios will return to normal operation when receiving a DTMF signal.
Scrambler
When the transmitter has scrambler on. The receiver also needs to enable scrambler function. Otherwise, the sound received is noise or unintelligent audio.
