FTB-2 and FTB-2 Pro 259

Recharging the Batteries

To recharge the batteries:

Connect the unit to a power outlet using the AC adapter/charger. The

charge cycle will start and end automatically.

IMPORTANT

 Remove the batteries if the unit will not be used for more than

two weeks.

 If you need to store the batteries for an extended period of

time, place them in a cool dry place, and ensure that they are

charged at around 50 % of their capacity. Every three months

during the storage period, verify the battery level. Recharge the

batteries when necessary, so that their charge level remains

around 50 % of the total capacity. This will ensure that you get

the optimum performance out of the batteries.

 Li-Ion batteries that are not used for a long period of time (over

three months) will not be damaged, but might need to be

recalibrated.
