Maintenance and Troubleshooting
Maintenance
Merlin™ PCS and Merlin PSA: Service must be performed at the factory or by an authorized
service representative only. The Merlin PCS and its accessories, including the Merlin PSA, contain
no user-serviceable parts.
NOTE: For information on the Merlin PSA maintenance and troubleshooting, see the Merlin
PSA on-screen help.
Cleaning
To clean the exterior of the Merlin PCS, Merlin PSA, Merlin Antenna, and ECG cables, wipe the
exterior surfaces with a damp cloth moistened with a mild soap.
To clean the Merlin PCS touch-screen display, spray a small amount of diluted glass cleaner on a
soft cloth and gently wipe the screen. Dilute the glass cleaner by adding an equal amount of
water.
CAUTION: Keep liquid out of the system's interior. Never spray liquid directly onto the
Merlin PCS or its accessories.

WARNING: Do not modify the Merlin PCS without the authorization of the
manufacturer.
Programmer Self Test/Preventive Maintenance
When you turn on the Merlin™ PCS, the device performs a self-test of the internal hardware and
software. If the test fails, the programmer displays a message explaining the cause of the failure.
Should the self-test fail, turn off the programmer, wait 30 seconds, and then restart the
programmer. If the self-test fails again, contact Technical Support (page 1).
The programmer and its electronic accessories have been designed with digital circuitry and does
not require calibration.
Telemetry Wand Sterilization
To sterilize the telemetry wand and/or cables, place the item in a gas-permeable package and
sterilize it in ethylene oxide. Do not exceed 50°C (122°F). After sterilization, allow sufficient time
for complete aeration of ethylene oxide prior to use. This process may be shortened by forced
ventilation. Use biological controls to verify the effectiveness of sterilization.
CAUTION: Do not autoclave, radiation sterilize, or clean ultrasonically or with chemical
solutions.
Do not attempt to sterilize the Merlin™ PSA, the PSA Wand, the Merlin™ Antenna, or
the Merlin™ PCS itself.
NOTE: You can place the PSA Wand, the Merlin Antenna, or the inductive telemetry wand
inside a sterile glove or bag.
