A unique feature of this design is the access to the battery compartment with a sliding front door. Later most credit card sized calculators of the Canon brand used that type of battery compartment. Just view the LC-5 introduced about 1977.

The LE-84 and LE-85 were the next steps in cost reduction before leaving the design of LED-based calculators and introducing the LD-80 with the green VFD (Vacuum Fluorescent Display).
