CT30 XP protective boot. It

The Honeywell CT30P-PB-XP protective boot is an accessory for the CT30 XP mobile computer. It surrounds the handheld unit as a protective fit and is made for users who operate the computer with the boot attached.

To install it, insert the computer into the bottom of the boot and press down evenly until it sits securely. The boot can remain in place when replacing the battery or charging with a compatible base, so routine handling for those tasks does not require removing it.

It is compatible with Honeywell booted universal docks in the CT30P-XX-UVB-X family. The listed package contents are one protective boot.
