THE AC POWER CORD ATTACHED.

WARNING: ENSURE THE UNIT HAS BEEN CLEANED PER THE

CLEANING INSTRUCTIONS.

6.2 General Procedures

6.2.1 Examine the unit prior to disassembly or troubleshooting and
inspect for cosmetic damage. External damage may be
helpful in determining the root cause of the failure.

6.2.2 Note any markings or labeling the end user may have placed
on the unit that may need to be duplicated or transferred in
the event the housing or ancillary components are to be
replaced.

6.2.3 Make note of the unit serial number.

6.2.4 Make note of the software versions in the event the Oximeter
board or system boards are replaced, as these boards
require software updates to make them compatible with the
end users version of software.

6.2.5 Contact Masimo Corporation using the information in Section

7.2.4 to research the warranty history of the unit to
determine if the unit will be covered under warranty.

WARNING: A HI-POT SAFETY TEST IS REQUIRED IN THE EVENT

THE DOCKING STATION HAS BEEN DISASSEMBLED.

6.3 Troubleshooting

6.3.1 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. A safety analyzer or Hi­pot/Current Leakage test unit will be needed in the event the
Docking Station is disassembled. The Masimo SET Tester
will be needed to perform the Performance Verification in
Section 5 upon completion of repairs.

Radical-7 Signal Extraction Pulse CO-Oximeter Service Manual

6-1

Tools required are as follows:

Phillips head screwdriver
Multimeter
10mm wrench or small pliers

6.3.2 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.

6.3.3 Always note the software versions of all three boards prior to
repair.

6.3.4 All units must have Performance Verification in Section 5
performed after repairs have been affected.

6.3.5 All Docking Stations that have been opened must be safety
tested after reassembly.

6.3.6

Service Messages

6.3.6.1 R2.0.x.x – When a fault is detected, the unit either

watchdogs or displays “Service Required XXX” (where
“XXX” indicates one of the symptoms below), and
generates high priority alarm sound. In either case the
fault is latched until power is cycled or the alarm silence
key is pressed.

6.3.6.2 R2.1.x.x – When a fault is detected, the unit either

watchdogs or displays “XXX” and generates high priority
alarm sound. When the fault triggers watchdog alarm, it
is latched until the power is cycled or the alarm silence
key is pressed. But when the unit displays “XXX”, it also
resets itself to clear the fault. If the fault is one-time
event, software clears the fault and continues to operate
normally. If the fault is permanent, the Radical-7 will
display “XXX”, reset, display “XXX”, reset…

6.4 SatShare Diagnostics

CAUTION: As SatShare Diagnostics simulates physiological information

(SpO2 and Pulse Rate values), it should be performed with caution,
especially in areas with central monitoring. The attending nurse
and supervisor should always be made aware that SatShare
Diagnostic testing is being performed.

6.4.1

If the SpO2 and pulse rate values displayed on a multi-
parameter monitor is in question, perform the following steps.

6.4.1.1 Press Menu – General – SatShare Numbers – Yes.

6.4.2 With the Handheld docked and AC power applied,
disconnect the patient cable from Radical-7. Press the
following key sequence: Menu – About – More – 2 – 1 – 1
(see Service menu for number key assignments). Five (5)

different SatShare values can be selected by pressing
the Select key. The selected value will be displayed on the

multi-parameter monitor if the unit is working properly. The
SatShare Diagnostics feature times out if a key is not
pressed within 1 minute.

Note: During transient situations, the SpO2 and pulse rate values on the

Radical-7 and multi-parameter monitor may differ by more than the
specified tolerance. The averaging time set on the multi-parameter
monitor may also affect the delay during transient situations.
