PX-628 VHF/UHF 2-Way Radio FM Transceiver
Our PX-628 VHF/UHF 2-way radio FM transceiver is suitable for wireless communication command and dispatch in areas such as public safety, public utilities and security patrols. The product has many functions as followed.
Features and Functions
Features-The walkie talkie has many advantages including high audio quality, stable performance and long communication distance.
Scan-The function enables users to receive any call on the channel without hand operation. Scanning priority is set flexibly using write frequency software. Priority scan helps users to monitor commonly used channels and frequencies.
Busy Channel Lockout-The function disables transmission when the channel is busy, thus making the channel free from interference.
Selection of High and Low Power-The output power can be easily changed by write frequency software. Reasonable power is selected to save battery energy.
Monitor-Users can quickly and easily monitor a specific channel at the touch of the corresponding programmable button without waiting for specialized calls. The function can be used to receive weak signals.
Power Saving-Power switch can be turned on or off quickly by write frequency software. Working at receiving status but no signal is sent in, the transceiver will automatically enter power saving mode to reduce power consumption. As a result, its working time gets longer.
Time-out Timer-The time-out timer limits the time of each transmission to a certain period of time so that transmission won’t occupy the channel for too long. This function is necessary to protect the transceiver from thermal damage caused by long time of transmission.
