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