Dot% Function Missing From the 361 Menu (311 emulation mode)

The 361T replaced an earlier (and less powerful) model 311. The 361T was provided with a 311 emulation mode to ensure full backward compatibility for customers that had written computer interfaces. On occasion a customer will call asking "where did my Dot % go?". Invariably they have gotten the 361T into emulation mode. To restore normal operation proceed as follows:

• Turn the instrument off.
• Press and hold both the "FUNCTION" and "COLOR" keys. While holding both keys, turn the unit back on.
• The unit will perform its self-test and then prompt "<-311 ON".
• Press the "ZERO" key to toggle the display from "ON" to "OFF".
• Press the "FUNCTION" key to exit
