# During the recharge:
1. While the batteries are being recharged, a red and amber light will appear on
the battery charger, indicating that the power is connected and charging is in
progress.
# At the end of the recharge cycle:
1. The amber light will change to a green light. This indicates that the
batteries are fully charged and ready for use.
2. The battery charge level indicator on the controller should also
show a full charge when batteries are charged & power is switched on.
When do the batteries need recharging ?
When the batteries fall below 80% of the maximum charge level, the "on / off" lamp
on the controller will flash. This indicates that while you have some reserve power,
the batteries should be recharged.
Note:
1. Do not use batteries other than the recommended type for your chair and
never use a charger other than the one supplied for the purpose.
2. If the chair is not used for a long period of time (e.g., school holidays,
hospitalisation, or when vacationing) arrange to have the batteries charged
for at least one day (10 hours) every month, minimum.
3. Periodically, check that the battery terminals are clean and the connections
are tight. Smear a thin film of petroleum jelly on the terminals to guard
against corrosion. Always wash your hands after handling batteries.
