• Added: FW updates installation and management through new software Manager
• Added: commands optimization on Manager
• Changed: Reduce time of starting at 6.5 seconds
• Added: compatibility with Eneloop Pro

new – added HP filters at 200 and 300MHz

new – added the selection of the slope of the filter between 6dB/Oct or 12dB/Oct: the HPass filter menu allows to select the following filters:
“flat/60/80/120/170/200/250/300/400MHz” with a slope at 6dB/Oct or 12dB/Oct.
