5.1.2 Charging the Batteries

NOTICE
Charging non-chargeable batteries
Damage to the product due to battery leakage
Only connect the product to the battery charger when you are using rechargeable batteries.
►
INFORMATION
Rechargeable batteries lose capacity over the course of repeated charging cycles. This is a nor­
mal process.
Replace the batteries when the operating time of the product decreases noticeably.
►
Depending on the performance of the batteries, the vacuum level and patient activity, the battery
capacity of the vacuum pump is 2 to 3 days. The manufacturer recommends charging the batter­
ies daily. A complete charging cycle takes 4 to 6 hours. Remove the vacuum pump from the
product or take off the prosthesis during the charging process. The battery charge level is indic­
ated by signals shown in the table.

Assembling the Battery Charger

1) Connect the chosen adapter plug to the power supply (see fig. 8).
2) Ensure that the adapter plug engages in the power supply (see fig. 9).
3) Connect the USB plug of the charging cable to the power supply (see fig. 10).
→ The battery charger is assembled.
Charging the batteries
> Only charge the batteries with the battery compartment cover in place.
1) Set the selector switch to standby mode.
2) While wearing the prosthesis: Pull the vacuum pump off the adapter plate. Remove the out­
let hose from the vacuum pump if necessary.
3) Open the charging receptacle cover.
4) Insert the battery charger plug into the charging receptacle (see fig. 11); a signal indicates
that the charging process has started.
