FR-7b/FR-5b V-Accordion
The reason why the Treble and Bass sections do not
respond to this pedal is that you can control their vol-
ume via the strength with which you press and pull the
bellows (like on any accordion).
The expression pedal can be used to fade the Orchestra
part in and out, which is probably most effective in
DUAL mode (see p. 26). When the expression pedal is all
the way up (heel down), the Orchestra part does not
sound. Press the expression pedal down (toe down) to
increase the Orchestra section’s volume.
Note: The expression pedal can also transmit CC11 messages via
MIDI. See page 91.
Charging the battery
The FR-7b comes with one Ni-Mh battery that can recharged when it is depleted. Such a battery is optional for the
FR-5b. If you decide to purchase one (to play with a wireless system and no cables on stage), you should also read the
following.
• Be sure to dispose of used batteries in accordance
with local regulations.
• First, read the precautions on page 9 and following.
• The FR-7b’s battery is fully charged (and installed in
the FR-7b’s battery compartment). It can be used
right away.
• Be sure to fully deplete the battery (wait until the
FR-7b/FR-5b 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 “mem-
ory effect”.
• A fully charged battery should last about 8 hours
(continuous use).
• When the battery is fully drained, the following mes-
sage appears and the FR-7b/FR-5b goes off:
Note: The FR-7b/FR-5b contains an energy saving function
that switches off the instrument 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-7b/
FR-5b should wait before powering off automatically. See
“10.8 Auto Power OFF” on p. 73.
• Never try to insert other batteries into the FR-7b/
FR-5b than the one it came with (or suitable replace-
ment batteries purchased from your Roland dealer).
Only use “BP-24-45” batteries, part no. K2568101.
Warning: The battery body may become hot during
and after charge. Handle it with care to avoid burns.
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:
•Lights red: The battery is being charged. Depending
on the button that lights, this refers to the battery in
the FR-7b/FR-5b (BATTERY) or the battery attached
to the FBC-7 (EXTERNAL BATTERY).
•Lights green: The battery 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. This is nothing to
worry about: just take the FBC-7 to a place where the
ambient temperature 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 is overheating. Disconnect the
FR-7b/FR-5b (or the battery) from the FBC-7 and use
the battery until it is depleted. Then, recharge it.
•Flashes red: The battery cannot be fully recharged,
i.e. it takes more time than expected to reach full
charge. If this happens once, wait at least half an
hour, then try charging it again.
If the button again flashes red, the battery may have
reached the end of its life cycle. Replace it with a new
one if the button keeps flashing red.

Recharging the battery without removing it from

the FR-7b/FR-5b

There is no need to remove the battery from the FR-7b/
FR-5b in order to recharge it. Recharging the battery
takes ±3~5 hours and is therefore not something you
should do a few minutes before you intend to use the
FR-7b/FR-5b.
