The DME portion of this radio can show distance or ground speed on the LED display at the bottom. The ground speed information is displayed by pressing the OBS knob.
Other IDME-891 features include:
- Pendulum VOR/LOC needle and rectilinear Glideslope needle
- Solid-state design
- High-intensity LED display for DME information
- 25 watts transmit power

Additionally, the IDME-891's Marker Beacon Indicator requires a connection to a remote Marker Beacon Receiver, such as the MKR-101R or CP-136M.
