6 PREVENTIVE MAINTENANCE

INTRODUCTION
The BIS VIEW system is designed so that no periodic adjustment or calibration is required.
Suggested routine maintenance covered in this section includes:
• Periodic physical integrity inspection
• Replacing the PIC
• System checkout
• Checking the battery
• Checking leakage current
Instructions on replacing cables, connectors, the battery, the power supply and the clamp
shoe are included in Section 8, "Servicing the BIS VIEW System" if replacement is
necessary.
6.1

Physical Integrity Inspection

Periodically check the system (BIS VIEW monitor, BISx, PIC) for physical damage to cases
and associated cables and connectors.
1. Inspect the cases of the monitor and the BISx to ensure that plastic is not cracked or
broken.
2. Inspect the gasket seal around the case joining surfaces to insure the integrity of the
splash resistance seal.
3. Inspect the cables and strain relief mechanisms.
4. Inspect the connectors for damage, faulty strain relief or contamination.
6.2

Replacing the PIC (Patient Interface Cable)

The Patient Interface Cable (also known as the PIC cable) is considered a consumable part
of the system and is expected to wear out due to normal usage. The internal wires and/or
connector contacts may fail with fatigue over time or become contaminated with foreign
material. This is an expected occurrence, as it is with any equipment that utilizes lead wires
or patient connection cables. Therefore, it is recommended that the PIC cable be tested on a
periodic basis (see section 6.3 "System Checkout") and replaced if it has been in service for
more than two years.
The PIC cable date of manufacture is printed on each cable and is located on a white label
wrapped around the PIC cable. The manufacturing date code is identified in one of the
following methods:
• "PIC+ mmddyy" (month, day, year)
• "PIC+ mm/dd/yy" (month, day, year)
• "nnnnnnwwyy" (where ww is week and yy is year)
