a brief summary of the essential user settings. The charger’s screen displays the following information

11. Ni-Cd programs
A set of convenient charge programs for recharging Nickel-Cadmium batteries, as commonly
used for modelling purposes. When the charge / discharge program is finished, the screen
displays the name of the charge program alternating with the message „END“, together with the
charge time, the last (dis-) charge current, the charged-in (discharged) capacity and the battery
voltage, and continues to do so until you disconnect the battery. This information can often give
you a useful indication about the Ni-Cd pack’s charge characteristics and capacity, or warn you
if the charger has incorrectly assessed the pack as being „full“.
