Do not connect the battery directly to a power outlet or
insert it into a cigarette lighter socket in a car. High voltage
may cause excessive current flow, leakage of battery fluid, heat,
bursting or fire.
• If a newly purchased battery exhibits rust, generates heat or seems
abnormal in any other way, do not use it. Take it back to your
Roland dealer.
• Be sure to fully deplete a battery before recharging it for the first
time.
• Keep the battery out of reach of babies or small children. Ensure
that babies or small children cannot remove a battery from the
FBC-7 while it is being charged.
• Be sure to carefully instruct any person on the proper way of han-
dling a battery.
• Never dispose of the battery in a fire. Never heat it. Doing so may
melt the insulation, damage the gas release vents or protective
devices, cause combustion through chemical reaction with gener-
ated hydrogen, ejection of battery fluid, bursting or fire.
• Do not charge or use the battery with the positive (+) and nega-
tive (–) terminals reversed, as this may drain the battery or cause
abnormal chemical reactions. Under normal operation, this should
be impossible, because the battery or cable can only be connected
in one direction.
• Do not remove the outer tube from a battery or damage it.
• Do no strike or drop the battery. Strong impact can cause leakage
of battery fluid, heat generation, bursting or fire.
• Never try to connect two batteries in parallel as this may cause
leakage of battery fluid, heat generation, bursting or fire.
• Do not alter or remove protective mechanisms or other parts.
Never disassemble the battery.
• The positive (+) terminal section of the battery is equipped with a
gas release vent. Never deform this section or cover it. Do not
obstruct the release of gas as this could result in leakage of battery
fluid, heat generation, bursting or fire.
• Do not overcharge the battery by exceeding the predetermined
charging period of the FBC-7 or indicator. Never recharge a bat-
tery that is already fully charged. This could result in leakage of
battery fluid, heat generation, bursting or fire.
• If the battery is not fully charged after the predetermined charg-
ing period has elapsed, stop the charging process. Prolonged
charging could result in leakage of battery fluid, heat generation,
bursting or fire.
• If any fluid from a battery comes in contact with the eyes, flush
the eyes immediately, washing them thoroughly with clean water
from a tap or other source and consult a doctor. Strong alkaline
fluid can damage the eyes and lead to permanent loss of eyesight.
• If skin or clothing comes in contact with any fluid from the bat-
tery, wash the area immediately with clean water from a tap. Bat-
tery fluid can cause skin damage.
• When a battery is no longer usable, dispose of it in accordance
with all applicable local laws and regulations.
• If the battery leaks fluid, changes color or shape or changes in any
other way, do not use it, otherwise it may cause heat generation,
bursting or fire.
Strap holder precaution
• Never unscrew the strap holder rings to avoid damaging the
FR-7b/FR-5b’s plastic housing, which eventually compromises
overall stability and safety.
