D.1.4 Charging the Battery
The Fire Simulator uses NiCd batteries as a rechargeable power source.
When the batteries are fully charged, the simulator operates for at least 60
times without recharging. An internal buzzer is sounded when the voltage
from the batteries is lower than the required operational level.
➣ To charge the battery:
1 Place the Fire Simulator on a table in a safe area.
2 Turn the sealed plug (next to the operation button) counter-clockwise
with a suitable wrench.
3 Connect the battery charger.
4 Charge for a maximum of 14 hours.
5 Disconnect the charger.
6 Tighten the sealed plug clockwise.
Warning: Charge the simulator only when the battery is fully discharged.
During activation of the flame simulator, buzzer activation indicates that the
battery is discharged.
