(4) Press the [BATTERY¥CHARGER] button on the 
FBC-7.
The [BATTERY¥CHARGER] button now lights red.
(5) Wait until the [BATTERY¥CHARGER] button lights 
green, then switch off the FBC-7 and disconnect 
the 19-pin cable from both the FBC-7 and the 
FR-7/FR-5.
Disconnecting the FR-7/FR-5 is only necessary if you 
do not want to use the FBC-7 during your next per-
formance.
Note: You can use the FR-7/FR-5 while its battery is being 
recharged, provided you leave the V-Accordion connected to 
the FBC-7.
Recharging the battery on the FBC-7
The battery installed in the FR-7/FR-5’s compartment 
can also be removed and recharged on the FBC-7 itself. 
That is more tedious, though, and does not speed up 
the recharging procedure.
The main use for the method described below is there-
fore to recharge a spare battery (which is optional) 
while using the battery inside the FR-7/FR-5. If that is 
what you want to use the connector on the FBC-7 for, 
skip to step (7) below.
Warning: Before removing the battery, be sure to 
power off the FR-7/FR-5 (the blue indicator must be 
dark).
(1) Switch off the FR-7/FR-5.
(2) Prepare a coin.
(3) Remove the cushion located between the Treble 
keyboard and the bellows.
(4) Use the coin to loosen the two screws of the com-
partment cover.
(5) Remove the cover from the FR-7/FR-5’s battery 
compartment.
Note: While the compartment cover is open, the FR-7/FR-5 
cannot be switched on.
(6) Pull the battery strip so that the battery protrudes 
a little from the battery case, and then remove the 
connector and take the battery out of the battery 
case.
The battery is connected to the FR-7/FR-5 by means 
of a cable. You need to disconnect the cable from the 
battery by pressing the clip on the connector before 
fully removing the battery.
Note: Please pull the strip installed on the battery and take the 
battery out.
(7) Slide the FBC-7’s EXTERNAL BATTERY CHARGER 
cover to the right and remove it:
That portion on the FBC-7 now looks as follows (note 
the connector):
