USB intelligent charger charging
USB design of independent, free and computer, mobile power supply, mobile phone charger USB port connection, convenient life.

25kHz/12.5kHz conversion
The user can through computer programming software to set each channel bandwidth is 25kHz or 12.5kHz, and can switch over between different bandwidths, which can avoid re purchase.

CTCSS / CDCSS
The unique CTCSS /CDCSS encoding & decoding function can avoid listening to the same channel on the irrelevant call.

Chinese and English voice broadcast channel, functional operation and charging tips
Designed for the dim light of the environment design, walkie talkie in the user's operation, can issue a variety of sound prompt operation state, can accurately issue channel broadcast in English and Chinese prompts, voice prompt power
status. Support Chinese and English language.

Emergency alarm
When the user is in an emergency or unexpected situation, press the alarm button will immediately alert the intercom. In addition, it can also send out the identity code or background tone to inform the peer support.

voice control
Automatic control of sound transmission function, can be carried out by launching the operation, without the need to manually press the PTT key launch.

Launch timing function
This function is to prevent any caller occupied the channel time is too long, the timer to limit the number of times each time to launch the walkie talkie, limiting the user timeout launch.

Busy channel lock
This machine can store up to 16 channels.

Automatic power saving function
When the channel is idle or does not carry out any operation (12 seconds), the battery energy saving function is automatically turned on, and the walkie talkie starts to switch the receiving circuit alternately at a certain time, which has
achieved the purpose of automatic power saving and energy saving. The time ratio of the switch circuit can be set by programming software.

computer programming
The data can be connected with the computer through the data line to the interphone frequency data, the function parameter and the signal and so on carries on the programming.

Intelligent design
Dot matrix LCD screen with Chinese and English voice prompts, friendly interface, more convenient to control and select the function

Large capacity channel storage
Up to 128 memory channels are available for programming frequency and various other data

Rich signaling
Each channel can set different CTCSS / DCS, DTMF signaling, reject redundant calls from other stations

The tail is eliminated
Tail to eliminate, to avoid the end of the call after the impact of noise emitted by the speaker, to avoid the user by the impact of noise

VOX voice transmission
Voice-activated transmission function (VOX), allowing users to liberate their hands, without pressing the PTT button to normal call

Pilot and scrambling functions
Equipped with the use of the cluster network transmission pilot, scrambling function, to adapt to a variety of complex conditions set requirements

Full manual operation
Menu item keyboard digital direct election function, the transmission and reception frequency can be input directly

strong and sturdy
Normal temperature of one meter of water immersion for 30 minutes does not cause harmful effects, anti-1.5 m drop, resistance to 1.5 tons of heavy roller, waterproof seal, natural dust.

High / low power switch
Users can set the channel power through the computer programming software for high power or low power, or manually switch the high and low functions, according to the actual use of the environment and distance requirements, select a
reasonable power, effectively save power.
