Clear SD:
Press “DO” to initiate SD card memory purge. KHG has log feature for user analysis. However, the record
log takes up memory on the SD card, and we recommend performing the SD card memory purge every 3
months. Low available SD card memory will slow down the display refresh speed. Every time you do a “Clear
SD”, please unplug KHG from power outlet for 3 seconds and reconnect the power cord to the electrical
outlet. This will reboot the system to re-enable the logging function.
