ST80i Stress Test System Instructions for Use xiii
Caution Statements for the Wireless Patient Interface
Module
CAUTION Failure to heed these caution statements may result in damage to equipment or software.
The wireless patient interface module complies with FCC radiation exposure limits set
forth for an uncontrolled environment.
The wireless PIM supports 1.5V AA alkaline batteries only. Replace the battery if the
low-battery alert appears before the stress test starts.
The wireless PIM uses an off-the-shelf disposable AA alkaline battery for power. If you
use an off-the-shelf rechargeable AA battery, the remaining capacity indication may be
inaccurate.
Minimum operating time of the wireless PIM with new, fully charged batteries: 6 tests per
day, 30 minutes average per test, for 5 days. Performance may vary according to brand of
batteries used.
If you use off-the-shelf rechargeable batteries, then you must also provide a compatible
battery recharging unit independent of the ST80i System. To ensure safe use and adequate
maintenance of rechargeable batteries, follow the battery manufacturer’s instructions for
use.
Other than the replaceable battery, there are no user-serviceable parts inside. Any
modification of this device may alter defibrillator protection. Any modification to any part
of this device is to be performed by qualified service personnel only.
Follow the correct procedure to select the wireless PIM when multiple modules are
detected. See “Select the PIM” on page 3-13 of the “The Patient Session” chapter.
To prevent possible damage to the keypad, do not use sharp or hard objects to depress
keys; only use fingertips.
The wireless PIM and patient lead set should be cleaned between each use.
Do not attempt to clean the wireless PIM or patient lead set by submersion, autoclaving, or
steam cleaning. Wipe the exterior surface of the device and patient cables with a non-
alcohol sterilizing disinfectant, then dry with a clean cloth. See “Cleaning the ST80i
System” on page 5-2 in the “Maintaining the ST80i System” chapter for a list of approved
disenfectants.
Conductive parts of the patient lead sets, electrodes, and associated Type CF connections,
including the neutral conductor of the patient cable and electrode, should not come into
contact with other conductive parts, including earth ground.
Do not pull or stretch patient lead sets as this could result in mechanical and/or electrical
failures. Store lead sets after forming them into a loose loop.
The following equipment may cause interference with the RF channel: microwave ovens,
diathermy units with LANs (spread spectrum), amateur radios, and government radar.
