5.8.5. Firmware download Download of firmware is normally required when functional upgrade is needed or when bug or erroneous actions of firmware are fixed. Downloading improper images (executable file of repeater CPU) may cause seriously harmful damages to equipment. Download takes the following steps. ① Convert firmware source file (*.bin) to a downloadable file format. Main menu: Action → Image Compression, toolbar: ② Open a pop-up window showing the status of the target equipment for firmware download.
Download procedure Display selected file information Select file Perform operation Display progress of firmware download 5.9. Additional features 5.9.1. ASD (Auto Shutdown) Function 1. If the power level is above the shut down level for longer than 1 second, turn off HPA. 2. During shut down state, monitor RFCHS output power. If the level is below 5dB from shut down level, turn on HPA automatically. 3. Monitor HPA output power in normal operation, and monitor RFCHS output power during shut down.
1. If the power level reaches the ALC level, prevent to increase more than ALC level by using ATT control. 2. By memorizing the existing ATT value, the ATT value before ALC can be reused even when the power is reduced.
