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 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.
