GEM Manual

3. Getting Started
When power is applied to the display, a start-up screen displays for approximately 7 seconds while
the display performs a self test. If the display makes a ‘bleeping’ sound for longer than 1 second, selftest
has failed. Users can attempt to rectify the fault by restoring factory defaults (see Configuration
menu/section 10 for details); if the fault persists, contact your supplier for guidance.
After the start-up screen disappears, the GEM starts displaying readings on its virtual gauges if it is
connected to an active source of data. The GEM displays the ‘main engine display’ or tri-screen on
initial start-up, but note that after use this changes to the screen that was last displayed (see Preferred
Screen Store/section 13 for details). The GEM display modes are detailed in the following sections.
