ERR:Error
*CHK CLIP* Check alligator clips
*OVER VOT* Over voltage error occured. The
voltage of charging battery is higher than the
voltage of power supply. Decrease charging amp
or increase voltage of power supply.
*OVERHEAT* The CM is very hot.
Do not block the air flow around slots or the fan
inlet in the back of the case. This could cause
excessive heat build up and may short out the
output circuit FETs which would void warranty.
Blow out dirt in the fan and heatsink area
occasionally. Otherwise there may be excessive
heat build up that could cause the unit to fail.

Auto start Timer:
This convenient feature lets you preselect when
you want to start the CM for a charge session:
adjustable from 0 to 18hours.

Delta peak value setting(Threshold setting)
03 means 3mV(0.003V). The delta peak value entered is the drop in
millivolts that the CM looks for to determine that battery pack has peaked.
This is adjustable from 03~99mV/pack. To adjust,push the
buttons. If you set up high delta peak value, the CM will charge longer
time. We recommend to start charge with 03mV for all batteries at the
beginning. Under certain conditions, a battery pack or cell can exhibit a
false peak. Under these circumstances, it peaks before it is charged, and
the result is that battery pack or cell does not receive a full charge.
False peaks can be caused by several things. Batteries that have been fully
discharged can false peak for several minutes. Use long lockout to alleviate
this problem. Another cause is using alligator clips on solid leads. This can
produce a poor connection that can’t handle the charge current. It is best
to clip onto braided wire or multi-stranded wire where more area is
contacted by alligator clips.
LONG LOCKOUT CHARGE(can be used PEAK, CTX CHG, CYCLE)
Set long lockout charge time(1~30min) at USER SETUP(page4)
Press and hold key for 2seconds. If long lock out charge acts,
mark will be shown instead of delta peak value.
ZERO DELTA PEAK(Set delta peak value at 00(0mV))
The CM has Zero delta peak charging cut off system which can cut off
charge at the peak voltage if the peak voltage stays for 7seconds(If this
condition is not satisfied, the CM will cut off by 3mV). For preventing from
false zero delta peak before it is charged, zero delta peak will act after
70% charge of set capacity. (See graph2)

Charging current(Ampere)
For battery’s safety and life time, always charge
under 4A for Sub-C type,
2A for AA, AAA type batteries.
