How to adjust the settings on all AHA and AHS systems using the front LCD panel and buttons.
The AHA and the AHS have the ability to be adjusted for frequency and voltage output levels.
In the manual it says when the UPS is plugged in, start the UPS with the two start buttons. Then using the select button to select the function to change and then set that parameter.
What is missing is this little piece.???
Plug the UPS in to the AC mains and DO NOT TURN ON. — Do not push the two buttons to start it.
While just in idle mode, select the function to adjust by scrolling through the LCD windows and adjust it and then turn the UPS on using the normal two button start process as in the manual.
This will lock the new parameter into the UPS.
