In 16C mode no [ON]/[...] combination works, when the calculator is off, pressing and holding [ON] will turn the calculator on immediately. If you try to press and hold [-], then [ON], the calculator hangs and you will have to press the reset button under the battery cover. So in 16C mode you can't get a comma as a decimal separator, reset memory.
The other [ON]/[...] combinations described in the original 16C manual - [ON]/[÷], [ON]/[×], [ON]/[+], will also cause the calculator to hang.
