5.3. Troubleshooting

5.3.1. The troubleshooting procedures in this manual instruct the

technician to isolate the failure down to the sub-assembly level.

The intention is to have the Unit Under Test (UUT) repaired with

minimal steps. The Masimo Set Tester is needed to perform the

Performance Verification in Section 4 upon completion of repairs.

5.3.2. Tools required are as follows:

Phillips head screwdriver #0

Multimeter

5.3.3. The troubleshooting steps below are presented in order of the

most probable cause first. Proceed to the next step only if unit

continues to fail.

5.3.4. Always note the software versions of boards prior to repair.

5.3.5. All units must have Performance Verification Section 4 performed after

repairs have been affected.

5.4. Service Messages:

Upon detection of a system error, the main software alerts the

user with an audible alarm indicator and displays the appropriate

error code on the Handheld’s main display. The MS-X board is

held in reset and no other runtime functionality is available to the

user until the Handheld is power cycled by the user (with power

on and off key) or until power is completely removed and re-

applied to the system (removal and replacement of batteries).
