CHARGE MODE
Charging at 200 mA is the default-operating mode of the charging unit.
When only one or two rechargeable batteries are charged, provided that only compartment 1
and compartment 4 are used, a charging current up to 1500 or 1800 mA may be set by the
pressing the CURRENT key.
On the other hand, when charging three or four rechargeable batteries at the same time, user
may select a charging current of 200, 500, 700 or 1000 mA.
When charging two batteries at
compartment 1 & 4 – max.
charging current: 1800 mA When charging two batteries at
compartment 1 & 2 – max.
charging current: 1000 mA

The estimated time of charging by various charging current is tabulated in Table 1.
When charging four batteries –
max. charging current: 1000 mA When charging two batteries at
compartment 2 & 3 – max.
charging current: 1000 mA

Note:
 User shall always observe the recommended maximum charging current of the
rechargeable batteries. In general, 200 mA is a recommended charging current if rapid
charging is not necessary. It is definitely safe and optimum to the rechargeable
batteries.
 It may be necessary to charge and discharge the new rechargeable batteries several
times in the beginning before the optimum capacity of the rechargeable batteries can
be obtained. It is recommended to use the "Refresh" mode for new rechargeable
batteries in order to achieve the optimum battery capacity.
 When the transformer has been plugged into the power source, the version number of
the charger (for example “33” ) will be displayed first. Then all the segments will light up
momentarily and the “null” sign will be shown before batteries are placed. If damaged
batteries are placed into the charging unit, the charger will also show “null” on LCD.
“null” displayed - No battery or damaged battery is
placed to the charging unit
