Boot-Up Test Sequence
When power is initiated to the Display Head, the screen will power up with a test sequence that satisfies the
requirements of the local Weights and Measures authority. The Display Head test sequence follows below:
• Run self tests
• Self test passed
• Checksum
• All segments of the display are activated (see Figure 3)
Figure 3. All Segments Activated
• All zeros appear in the four display value fields (see Figure 4)
Figure 4. All Zeros Activated in the Display Fields
• Version number
On initial startup of EMR4 Systems with two Display Heads, you must go to the Head Address Setup (Figure 27
on page 28) and assign an unique Head Address for each Display Head. Because the factory default Head
Address is set to a “1”, one of the two Display Head’s addresses must be changed to a “2”. Caution! Failure to do
so will cause communication problems which will result in erratic operation.
Subsequently, if no button press or operation occurs in 30 seconds, the display will go blank and wait for a button
to be pressed to reactivate. Initially, when reactivated, the Display Head enters the Volume mode.
Once the unit has been setup, the default reactivation mode will be the Pre-Dispense mode you choose in setup.
Also, if you enable the OEM message in setup, it will scroll across the Descriptor field until the 30 second timeout.
