MAINTENANCE
Attempting to recharge non-rechargeable batteries is dangerous
and could result in damage to the 8720 or possible explosion.
Follow these step to recharge the internal batteries:
1. Check that rechargeable (NiMH) batteries have been
installed and that the selection switch inside the
battery compartment is set for rechargeables (NiMH).
2. Connect the external power supply to the 8720 and
plug the external power supply into the wall socket.
Recharging will take about two hours. The 8720
may be used during this period, but the recharging
time may be significantly longer.
Replacing the Batteries
The 8720 will operate using either rechargeable (NiMH)
or non-rechargeable (Alkaline) batteries. The battery
compartment is accessible on the bottom rear of the unit

1. Turn off the 8720 using the power switch.
2. Open the battery compartment cover.
3. Remove the batteries.
4. Set the battery selection switch to the correct

An incorrect setting could lead to damage to the unit or personal
injury.
