40 DRAFT P440 Data Sheet / User Guide
4.11.1 Enclosure
The enclosure is intended to provide a modest level of protection for the boards. The primary goal is
to avoid damage from light handling, accidental drops on the floor, coffee spills, and the like. The
enclosures also make it easy to safely and conveniently take measurements in buildings and outdoors.
The enclosures are NOT waterproof or rain proof. A photo of the enclosure is shown in Figure 26.
Note that underneath the enclosure are 4 rubber feet which conceal four 4-40 (not metric) mounting
holes. Those holes are suitable for attaching the unit to a fixed object.

4.11.2 Power Supply/Charger with Battery and Cables
P440s provided with Kits and Labs are powered through the USB Power jack. Time Domain also
provides each P440 with a USB Power Supply/battery charger, two USB cables (1.8 m and 15 cm)
and a 3000mAh USB battery.
Power supply: The power supply is intended for use with the standard North American wall plugs.
For units shipped outside North America, the power supply is also provided with an interface plug
(see Figure 27). Every attempt is made to provide an adapter compatible with the end user’s power
system, but this cannot be guaranteed. Please indicate your preference when ordering your
equipment.
