V-Accordion r If the battery fails to last 8 hours (or slightly less)
The button now lights red. (14) Wait until the [EXTERNALÂ¥BATTERYÂ¥CHARGER] button 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 actually need it.
Note: You can use the FR-7/FR-5 while the battery is being recharged externally.
If the battery fails to last 8 hours (or slightly less)
The FR-7�s battery (and an optional battery for the FR-5) 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.
(15) Reinstall the cover on the EXTERNAL BATTERY RECHARGER compartment and slide it to the left until it clicks into place. sUsing the recharged battery (16) Switch off the FR-7 (or FR-5). (17) Prepare a coin. (18) Remove the cushion located between the Treble keyboard and the bellows.
(19) Use the coin to loosen the two screws of the compartment cover.
Note: While the compartment cover is open, the FR-7/FR-5 cannot be switched on.
(20) Remove the depleted battery and disconnect its cable. (21) Connect the cable to the new battery and insert the charged battery into the FR-7/FR-5�s compartment. (22) Close the FR-7/FR-5�s battery compartment and re-install the cushion.
Note: Be sure to tighten the two screws all the way to establish firm contact between the compartment cover and the instrument. Otherwise, you won�t be able to use your FR-7/ FR-5.
