Introduction

The PR-5 is a low-cost, easy to use, 5 lb rate
computing scale featuring the most commonly
used letter and small parcel rates offered by the
United States Postal Service.

Housed in an attractive and durable gray­colored plastic enclosure, the scale looks great
on any desk at home or in the office.

The scale features a 6-key silicone rubber key­pad, which is usually found on more expensive

scales, and displays its numerals on a 4-digit,
easy-to-read LCD display. Six annunciators let
you know clearly what rate is currently dis­played.

A large (6" x 8") plastic platter allows for easy
rate calculation of larger envelopes. An envi­ronmentally friendly AC adapter is included at
no extra charge.

Getting Started

After unpacking the scale, a small amount of assembly is required:

þ Locate the platter and affix to the scale in the holes provided. Be sure to align the end marked

“FRONT” with the front of the scale.

Please Do...

þ Plug the enclosed AC Adapter into the scale first, then into an AC outlet.

back of the scale. You may leave the scale on at all times, if you wish.
