Radofin 1610 Handheld Electronic Calculator

<< >>
This basic handheld electronic calculator has a black plastic case and nineteen oval indented plastic keys. These include ten digit keys, four arithmetic function keys, a % key, a total key, a decimal point key, a clear key, and a clear entry key. At the left in the top row of keys is an on/off switch. Behind the keyboard is an eight-digit red LED display. Text at the top reads: Radofin. A jack for a power adapter is on the left side.
The back of the calculator has a battery compartment for a nine-volt battery. A worn sticker below this reads in part: Radofin 1610 (/) Model 1610. It also reads in part: HONG KONG. A pen mark on the sticker reads: #28779. Text in molded plastic at the base of the back reads: HONG KONG.
Compare objects 1986.0988.146 (Radofin 8P) and 1986.0988.221 (Radio Shack EC-221). The calculator is closer to the EC-221.
