TM-V71 / Name Display
Name display on the radio can be controlled two ways:

The programmer sets Show Name to on for all Programmable Memories. If a name is entered, it will be displayed. If no name is entered, the frequency is displayed. To turn off name display, uncheck Show Name for each Programmable Memory.

The radio can be toggled between name and frequency easily from its face. Press the Tuning Control knob (large one at lower left) briefly for toggle. The selection remains even when the radio is powered off and back on.
