Charging the Internal Batteries

Replacing the Batteries

DEVICE PROGRAMMING UNIT USER'S MANUAL
The DPU display will indicate when the internal batteries
require replacement or recharging. If rechargeable
batteries have been installed in the DPU, they can be
recharged by using the external power supply provided.
Attempting to recharge non-rechargeable batteries is dangerous
and could result in damage to the DPU 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 DPU and
plug the external power supply into the wall socket.
Recharging will take about two hours. The DPU may
be used during this period, but the recharging time
may be significantly longer.
The DPU will operate using either rechargeable (NiMH)
or non-rechargeable (Alkaline) batteries. The battery
compartment is accessible on the bottom rear of the unit
(refer to Figure 1, page 2) without the use of tools. Follow
the procedure below to replace the batteries:
1. Turn off the DPU using the power switch.
2. Open the battery compartment cover.
3. Remove the batteries.
4. Set the battery selection switch to the correct
setting for the batteries to be installed.
An incorrect setting could lead to damage to the unit or personal
injury.
5. Install the batteries.
6. Close and lock the battery compartment cover.
