File → Channel Preferences
Channel preferences control how channel values are displayed — unit conversions, decimal places, and formatting. Preferences are applied per application or device, not stored in the configuration file.
Channels are stored and logged in their base metric units internally. Preferences only affect display — configuration files and log files remain unit-agnostic. This allows configs and logs to be shared across regions, with each user viewing data in their preferred units.

File → Device Settings
Device settings are stored on the display hardware and persist independently of the loaded configuration.
Select the display time zone from the dropdown. This affects timestamps on logged data and any time displays on the dash.
Changes take effect immediately on the connected device.
File → Firmware Upgrade
Firmware upgrades update the display operating system and runtime. A firmware update is required before loading configurations that use features introduced in newer firmware versions.
Do not power off the display during a firmware upgrade. The upgrade dialog shows progress and will report when complete.
Firmware files are also available from EmUpdater. See Display Release Notes for version history.
File → Bluetooth Settings
Bluetooth settings are stored on the display hardware. Use this page to pair phones or other devices for audio playback through the display speakers.
Enable Act as Bluetooth Speaker (A2DP Sink) to allow the display to receive audio from a paired phone or tablet. This is commonly used for telemetry voice alerts or music playback through the dash speakers.
Bluetooth settings persist across configuration changes and power cycles.
