Charging the battery pack
The FR-7 comes with one Ni-Mh battery pack that can
be recharged when it is depleted.
General remarks about the battery pack
•Please read “Precautions for the included battery” on
p. 6.
•The FR-7x’s battery pack is partly charged (and
installed in the FR-7x’s battery compartment). It can
be used right away.
• We recommend depleting the battery pack (wait until
the FR-7x goes off) before recharging it for the first
time. It would actually be a good idea to repeat this
the first three times to avoid the dreaded “memory
effect”.
•A fully charged battery pack should last about 8
hours (continuous use).
• When the battery pack is fully drained, the following
message appears and the FR-7x goes off:
Note: The FR-7x contains an energy saving function that
switches the instrument off when it is left unattended for
more than 10 minutes. You may therefore have to switch it
on again from time to time. You can specify how long the
FR-7x should wait before powering off automatically. See
“10.12 Auto Power Off” on p. 92.
• Never try to insert other batteries into the FR-7x than
the one it came with (or suitable replacement batter-
ies purchased from your Roland dealer). Only use
“BP-24-45” batteries, part no. K2568101.
Note: You cannot recharge the battery pack inside the
FR-7x and a battery pack connected to the FR-7x simulta-
neously.
About the BATTERY CHARGER and EXTERNAL
BATTERY CHARGER indicators
The FBC-7 has two buttons ([BATTERY¥CHARGER] and
[EXTERNAL¥BATTERY¥CHARGER]) that light or flash in
various ways to indicate the current status. Here is how
to “decode” those indications:
Note: If the red indicator goes off while the battery pack is
being recharged, this means that there has been a power fail-
ure and that the battery pack has probably only been partially
recharged. In that case, you need to recharge it again.
Recharging the battery pack without removing it
from the FR-7x
There is no need to remove the battery pack from the
FR-7x in order to recharge it. Recharging the battery
pack takes ±3~5 hours.
(1) Connect the FR-7x to the FBC-7 using the supplied
19-pin cable.
See “Connecting the FR-7x to the supplied FBC-7” on
p. 16.
(2) Connect the FBC-7 to a suitable wall outlet.
(3) Switch on the FBC-7 by pressing its [POWER¥ON]
button (its red POWER ON indicator lights).
(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-7x.
Disconnecting the FR-7x is only necessary if you do
not want to use the FBC-7 during your next perfor-
mance.
Note: You can use the FR-7x while its battery pack is being
recharged, provided you leave the V-Accordion connected
to the FBC-7.
Button Meaning
Lights red The battery pack is being charged.
Depending on the button that lights, this
refers to the battery pack in the FR-7x
(BATTERY) or the battery pack connected
to the FBC-7 (EXTERNAL BATTERY).
Lights green The battery pack is fully charged and can
be used again.
Flashes yellow
right away
The charging operation cannot be started
because the ambient temperature lies
outside the 0°~40°C range. Take the
FBC-7 to a place where the ambient tem-
perature is acceptable, wait a little, and
repeat the charging operation.
Flashes yellow
after a while
If the indicator first lights red and then
starts flashing yellow after a while, the
battery pack is overheating. Disconnect
the FR-7x (or the battery pack) from the
FBC-7 and use the battery pack until it is
depleted. Then, recharge it.
Flashes red The battery pack cannot be fully
recharged, i.e. it takes more time than
expected to reach full charge. If this hap-
pens once, wait at least half an hour, then
try charging it again.
If the button again flashes red, the battery
pack may have reached the end of its life
cycle. Replace it with a new one if the
button keeps flashing red.
