Pre-Installation Testing
Before mounting the equipment, it is recommended that you first verify its operation as
follows:
1. Power ON the unit and let the power-on diagnostics run.
2. Look in the upper-left corner of the display for any diagnostic failures or other system errors.
The monitor will start up normally if no unacceptable diagnostic errors occur. Refer to
Troubleshooting on page 5-1 for more information on the diagnostics features if the monitor
does not start up normally.
3. Insert at least one parameter module for testing purposes.
4. Refer to Preventive Maintenance (PM) Procedures on page 4-3 and complete those
procedures.
Mounting
The monitor can be mounted in one of three ways:
Wall Mount — The unit is attached to an adjustable mounting arm that projects out from a wall
track. This mounting scheme is suitable for a bedside configuration.
Pedestal Mount — The unit is securely attached to a flat surface, such as a shelf or an
operating room cart.
Roll Stand — The unit can be easily rolled from one location to another.
The 90387 can also be operated unmounted in a free-standing, table-top configuration, or it can be
console-mounted.
For installation requirements of the module housing(s), refer to the Module Housings and Power
Supplies Service Manual (P/N 070-0680-xx, located on CD-ROM 084-0700-xx).
Base Tension Adjustment (90385)
The 90385 monitor’s base can be adjusted to increase or decrease the tension that allows tilting of
the monitor screen. Tension is factory-adjusted for optimum performance and further adjustment is
usually not necessary. If adjustment is necessary, turn the base screw clockwise (refer to
Figure 2-1) to increase base tension or counter clockwise to decrease tension. Set the tension
loosely enough to allow normal viewer adjustments, yet tightly enough to hold the adjusted position.
