This chapter describes how to connect and charge the battery of
your Cordless.
Note: If you are using the DT430 or another phone that was
equipped with an intrinsically safe battery for EX-
classification, you need to loosen the screws at the back of
the phone, see DT430 on page 90 in this section.

The DT400, DT410 and DT420 are supplied with a high capacity
nickel metal hydride (NiMH) battery. If you have more than one
battery available, you charge only the battery.
