Connecting the charger to the mains
The charger is supplied complete with interchangeable adapters for
different mains sockets (Fig. 6a). To change the adapter, disconnect
the charger from the mains socket, release the currently installed
adapter by pressing the key
and at the same time pull off the adap-
ter y (Fig. 6b).
With no adapter fitted, the battery charger can be connected to a
mains socket with the aid of a mains cable (not included) which is
inserted into the integrated mains connection socket (Fig. 6c).
Charging the batteries
The NiMH battery pack 45-56 can be charged either in the flashgun
or separately.
Warning: The flashgun must NOT be switched on while the battery is
being charged within the flashgun!
The battery pack is exhausted if the recharging time after a full-power
flash (e.g. in manual flash mode M) exceeds about 60 seconds.
The charging operation is monitored by a microcontroller in the bat-
tery charger. When the battery pack is fully charged, the charging
operation is terminated automatically and the battery charger swit-
ches to trickle-charge mode.
You can leave the battery pack connected to the charger in
order to ensure continuous readiness. However, if you do not
intend to use the battery pack for a long period, you should
disconnect it from the charger.
For safety reasons, the temperature of the battery pack is monitored
during charging and the charging time is also limited by a timer. The
charging time is about 2.5 hours for a fully discharged battery pack
and correspondingly shorter for a partially discharged battery pack.
• Connect the battery charger 970 to a mains outlet socket and to the
battery pack (the connector for the charger is on the bottom of the
pack). The charging operation starts automatically. The status of the
☞

battery charger is indicated by a two-colour LED.
> LED lights with red light: the battery pack is being charged.
> LED lights with green light: the battery pack has been fully charged
and the charger has switched to trickle-charge mode..
To identify an exhausted battery: Push the knurled slide in the battery lid to
the black mark.
To identify a charged battery: Push the knurled slide in the battery lid to the
white mark.
2.3.3 Operation with the NC battery pack (optional)
The NiCad battery should be charged for 5 hours before it is used for the
first time. The NiCad battery can be charged within the flashgun or external-
ly.
Warning: The flashgun must NOT be switched on while the battery is
being charged within the flashgun!
The NiCad battery is discharged if the recycle time after a flash exceeds 60
seconds.
Adjust the correct mains voltage on the charger prior to charging. The volta-
ge selector (fig. 5a) is located next to the plug and can be adjusted with a
small screwdriver.
The connection for the charger (fig. 5b) is in the base of the NiCad battery.
The adjoining pilot lamp lights up while charging is in progress.
The charging time for a completely exhausted NiCad battery is 5 hours. A
partly discharged NiCad battery requires a correspondingly diminished
charging time.
To identify an exhausted battery: Push the knurled slide in the battery lid to
the black mark.
To identify a charged battery: Push the knurled slide in the battery lid to the
white mark.
