4.7 Battery Charger
Use only the provided Ferno battery charger (M, Figure 8) to charge
Ferno batteries, and charge only Ferno batteries with the charger. For
complete use, maintenance, and safety information, refer to Ferno
publication 234-3588.
The charger output cable connects to an ICS. An adapter cable (N,
supplied) allows the charger to connect directly to the cot battery. The
charger has two indicator lights (red and green).
To charge the battery, see "Battery" on page 16 and "Integrated
Charging System" below.

4.8 Integrated Charging System (ICS®)
To charge a battery inside an ambulance, the Ferno ICS and iN∫LINE
fastening system must be used.
When the cot is locked in the fastening system (Figure 9), ICS charges
the cot main battery and disables powered operation. Confirm the ICS
is receiving power from the ambulance ignition, inverter, and/or outlet
switch.
If the battery has a very low charge, the ICS may not be able to charge
the battery. Connect the battery directly to the charger separate from
the ambulance and ICS.
