• With the “INC” button, you access the next setting (or with the button “DEC” the previous
setting or return to the main menu with the button “TYPE/STOP”.)
For NiMH, NiCd or Pb batteries, you can set the so-called trickle charge here.
Briefly press the button “ENTER/START”. Now the charge current blinks; set it as usual
with the buttons “INC” or “DEC” (50...200mA). When selecting “OFF”, the function is
deactivated. Save the setting with the button “ENTER/START”; the voltage stops blink-
ing.
• With the “INC” button, you access the next setting (or with the button “DEC” the previous
setting or return to the main menu with the button “TYPE/STOP”.)
As soon as a charge process starts, the internal timer starts as well. If the charger
cannot detect whether the battery is fully charged for whatever reason (e.g. with delta-U
detection), the charge process is terminated automatically after a set time if the safety
timer is set to ON. This protects the battery from overloading.

However, do not set a time which is too short, otherwise the battery cannot be fully
charged.
Calculate the time for the safety timer as follows:
Examples:
Battery capacity Charge current Timer time
2000mAh 2.0A 2000 / 2.0 = 1000 / 11.9 = 84 minutes
3300mAh 3.0A 3300 / 3.0 = 1100 / 11.9 = 92 minutes
1000mAh 1.2A 1000/ 1.2 = 833 / 11.9 = 70 minutes
Factor 11.9 is used to ensure that 40% more time is available before the safety timer
kicks in.
Briefly press the button “ENTER/START”. “ON” (or “OFF”) then starts to blink in the
bottom display line.
