EXPLANATION
• The tests currently specified in the service manual as being required after repair/reassembly might
not reflect current testing requirements or recommendations. To help provide the most current
minimum test requirements and recommended tests, a Level of Testing Guidelines table has been
provided.
• The Electrical Safety and Run-In tests currently specified in the service manual have been replaced
to provide the current test procedures (Electrical Safety Test, Run-In On AC Power). An Audio Test
procedure has been provided to check the audio volume.
• Procedures have been provided to verify:
NiCad battery is being charged within specification (NiCad Battery Charge Current Test).
Current drawn from NiCad battery, when instrument is operating on battery power, is within
specification (Standby Current Test).
NiCad battery can provide sufficient instrument operating time after being discharged and
recharged (Battery Functional Test).
Current drawn from backup battery, when instrument is off, is within specification (RAM Standby
Current Test).
Models 1561/1565 (see illustrations in “Electrical Safety Test” section)
power, is double insulated as a medical grade power adapter and does not require a connection to earth
ground. Models 1561/1565 are compatible with all previously released MedSystem III
has only two connections to AC
®
Infusion Pumps.
Certification to the applicable standards for ElectroMagnetic Compatibility (EMC) has been validated by
TÜV America.
NOTE: Model 1561 is ordered as 143032 and or Model 1565 is ordered as 2861089

RECOMMENDED ACTION
CAUTION
Turn the instrument off and disconnect it from AC power before disassembly. Static
charges will damage instrument circuitry. Observe proper grounding techniques (use
grounding strap) to prevent possible harm to static-sensitive components.
Add this Service Bulletin to the Technical Service Manual, as a supplement to the “System Functional
Tests”, “Troubleshooting”, and “Repair” Chapters.
NOTE: Restoration of Configured Parameters, Battery History Log Memory contents,
serial number, and special message can be corrupted during repair. Field Maintenance
Software (FMS) may have been used to customize configuration settings or program drug
lists for Dose Rate Calculator. All settings should always be verified for accuracy after
repair. For reprogramming instructions, refer to the appropriate FMS DFU.
1. Level of Testing Guidelines
Any instrument repair or disassembly requires testing, determined by the level of the repair/
disassembly. Use the Level of Testing Guidelines, Table 1, in place of the test requirements
