The manual truly is useless, but it's an automatic charger, aka smart charger. Pretty simple stuff.
Default discharge rate with that charger is 1.1v for nicad or nimh, which is fine. 0.7 amp discharge default setting on the screen is also good.
I can already see in the screenshot posted the settings are ready to go, I would hit the start button and eat some popcorn while I wait for the buzzer to go off.
The do's and don'ts are found on any other charger manual so you can refresh yourself on what you'd do manually.
You don't deep cycle NIMH batteries or cycle them. You can read any charger manual and become more enlightened what to expect. How about outdated to something current?
