The Konka BT4301 rear-projection TV is a high-quality color television that offers advanced features for both professional and home use. This model comes with two types of remote controls: one designed for factory technicians and another for general users. While both remotes have the same core functions, the factory remote includes a "Convergence" button, which is not accessible on the user remote. However, the user's remote actually has a hidden "Picture Still" button that can be used to access the convergence adjustment feature. This button is sealed inside the remote’s casing to prevent accidental activation by end users.
To adjust the convergence, you need to add a conductive button to the remote control, allowing access to the factory menu. Once in the maintenance mode, the TV screen will display a green square line. Pressing the "Call Sign" button will bring up the convergence adjustment interface, where red and green square lines appear, along with a small red cursor in the center. The goal is to align the red and blue squares with the green image accurately.
After making the necessary adjustments, press the "Audio" button on the remote to save the settings. Wait for three seconds, then press the "Convergence" button again to exit the adjustment mode. It's important to note that the TV should be powered on and preheated for at least 30 minutes before starting the convergence process to ensure accurate results. This step helps stabilize the internal components and ensures better performance during the calibration.
Online UPS provides continuous power to critical equipment, eliminating downtime during power outages. It offers protection against voltage fluctuations, spikes, and surges, making it ideal for data centers, hospitals, and other sensitive applications.
It is designed to protect sensitive electronics and prevent data loss or damage caused by sudden power disruptions.The primary function of an inverter UPS is to convert DC (Direct Current) power from a Battery into AC (Alternating Current) power that can be used by electronic devices. This conversion is achieved through the use of an inverter, which changes the battery's DC power into the AC power required by the connected equipment.
Our Bosin Inverter with UPS function power frequency energy-saving transformer with full-bridge pure sine wave output, low loss and high efficiency.They can unattended duty-free function may also offer the ability to remotely manage and control the UPS, allowing users to monitor its status, perform diagnostics, and configure settings from a central location.Support a variety of communication interface, remote monitoring via RS232/mobile App/Wi-Fi/GPRS.Automatic start when city power comes.It has three working model:Grid prior, Eco mode, PV prior.
One of the key features of an inverter UPS is its ability to provide uninterrupted power during a blackout. When the main power supply is interrupted, the UPS automatically switches to battery power, ensuring that connected devices continue to operate without any interruption. This seamless transition is crucial for systems that cannot afford any downtime, such as servers, medical equipment, or communication networks.
