Repair works must only be carried out by a specialist/specialist
workshop.
If you have queries about handling the device, which are not
answered in this operating instruction, please check with the
distributor for further help.

Power Supply
The shipped power adapter is the power supply for this charger. In case
you need to use other power adapter, please be aware that power supply
has the correct polarity plug. Also please be noted that power supply need
be able to supply minimum 1.0A current. Low output power adapter could
lead to working improperly.
When charger is powered up, version number is displayed for 2s. Then all
LCD segments will light up momentarily. “null” will be shown until any
batteries are inserted.
5.
Operation
Once a rechargeable battery is inserted, its present voltage( for example,
“1.12v”) will be displayed for 3 seconds, then 400mA default charging
current will be shown on display for another 3 seconds. If
MODE
or
CURRENT
button is not pressed during these 6 seconds, the charging
process will start. During the first 6 second time, If any button is pressed,
the unit will wait for another 10s before finishing current slot setting. Once
the first battery working mode has been entered, the next battery can be
inserted and choosing the desired working mode accordingly. While the
previous battery slot setting mode is in effective (telling by the flashing
display of that battery slot LCD ), and the next battery is inserted, then both
battery slot display will be flashing, which means that any setting change
will be applied for all batteries in setting mode at the same time.
Once normal working mode starts, charging current or working mode can
no longer be changed until batteries are taken out from charger and insert
into charger again, or mode button is pressed longer than 2 seconds..
During normal working mode, press DISPLAY button will toggle display
mode between battery voltages, working current, elapsed time for all the
slots in working progress.
Each button pressed will turn on back light for 30 seconds.
5.1 Mode Selection
Press and hold the “MODE” button for 2 seconds to start working
mode selection for all four battery slot.
Press the “MODE” button subsequently to toggle among the
“Charge”, ”Discharge”, ”Test” , “Quick Test” and “Refresh” mode
When particular slot working mode needs to be changed, detach the
battery from charger and insert the battery into slot again, while that
selected slot LCD display content is in flashing, press MODE button
to choose desired working mode.
When working mode is changed, working current adjustment is
possible also.
5.2 Current Selection
Within the first 6 seconds after inserting the battery or right after power up,
press the “CURRENT” button to select desired charge current for slots
loaded with battery at the same time. Current setting can not be altered
once the setting has been confirmed in the initial stage. If different working
current is needed afterwards, either changing the working mode or
rechargeable battery must be taken out and inserted again. Discharge
current is automatically set to predefined charge current.
Batteries for slot 1 and 4( no batteries present at slot 2 or 3), its charging
current can be selected for 1000mA further. Slot 2&3 maximum charging
current is limited to 700mA only.
5.3 Display Selection
“DISPLAY” button is for toggling display information for voltage, current,
capacity, work time etc.
6.
Overheat Protection
With our improved charging circuit design, for normal good quality battery
with low impedance, heating built up on battery during charging process is
almost unnoticeable. However during the last charging stage, when battery
is almost full, batteries can become warm. This is normal: the larger
charging current applied, the more heat will build up. When battery
temperature is sensed to be over 60C, then over heat protection will be
kicked in for safety reason. Beside the two battery temperature sensor,
there are also two temperature sensors located on controller board,
located at the area where most heat is generated. So both battery and
controller temperature is monitored during the operation of the charger.
When overheating occurs, either from battery over 60 degrees Celsius or
controller board over 77 degrees Celsius, current working mode will be
automatically halted. If controller board over heat is detected, over heat
protection will be applied for the corresponding 2 battery slots at the same
time. If battery temperature over heat detected, only the over heated
channel will be halted accordingly. To tell if it is in the state of overheating
protection mode, charging current will be reduced to 0mA.
Charging/discharging process will only resume after battery temperature
drops below 40 degrees Celsius and/or charger controller board drops
below 50 degrees Celsius.
