FR-7b/FR-5b V-Accordion
That portion on the FBC-7 now looks as follows (note
the connector):
(8) Connect the battery’s cable to the charger’s socket.
(9) Slide the battery into the holder on the FBC-7.
(10) Connect the FBC-7 to a suitable wall outlet.
(11) Switch on the FBC-7 by pressing its [POWER¥ON]
button (its red POWER ON indicator lights).
(12) Press the [EXTERNAL¥BATTERY¥CHARGER] button
on the FBC-7.
The button now lights red.
(13) Wait until the [EXTERNAL¥BATTERY¥CHARGER] but-
ton lights green, then switch off the FBC-7 and
disconnect the cable from the socket on the FBC-7
and from the battery.
You can leave the battery where it is until you actu-
ally need it.
Note: You can use the FR-7b/FR-5b while the battery is being
recharged externally.
(14) Reinstall the cover on the EXTERNAL BATTERY
RECHARGER compartment and slide it to the left
until it clicks into place.
■Using the recharged battery
(15) Switch off the FR-7b (or FR-5b).
(16) Prepare a coin.
(17) Remove the cushion located between the Treble
keyboard and the bellows.
(18) Use the coin to loosen the two screws of the com-
partment cover.
Note: While the compartment cover is open, the FR-7b/FR-5b
cannot be switched on.
(19) Remove the depleted battery and disconnect its
cable.
(20) Connect the cable to the new battery and insert
the charged battery into the FR-7b/FR-5b’s com-
partment.
(21) Close the FR-7b/FR-5b’s battery compartment and
re-install the cushion.
Note: Be sure to tighten the two screws all the way to estab-
lish firm contact between the compartment cover and the
instrument. Otherwise, you won’t be able to use your FR-7b/
FR-5b.
If the battery fails to last 8 hours (or slightly
less)
The FR-7b’s battery (and an optional battery for the
FR-5b) can be recharged about 300 times before it
needs to be replaced with a new one. Note that it is
normal for the battery to last increasingly shorter as
time goes by. At the end of its life cycle, it may only last
one hour, for example. But that is a gradual process.
Note: If the red indicator goes off while the battery is being
recharged, this means that there has been a power failure and
that the battery has probably only been partially recharged. In
that case, you need to recharge it again.
