leakage requirements for medical products. Consequently, all external
equipment must be kept outside the patient environment.
•
Never touch the electrical contacts on the side panels of the Model
3300 Programmer and the patient, a telemetry wand, or any cable at
the same time.
•
Wand temperature (Model 6395 only).
Telemetry procedures exceeding
8 hours may require a thermal insulator between the Model 6395
Telemetry Wand head and the patient’s skin as the wand head
temperature can range from 33 - 41 ºC (88 - 106 ºF).
•
PSA connections.
Ensure leads are connected appropriately for desired
use; incorrect setup can result in pacing/sensing events, which display
under a different chamber on the screen. The PSA application user
interface associates specific lead connections with the RA, RV, and LV
chambers on screen to support testing all three chambers with minimal
change of physical connections. Saved PSA measurements are also
labeled automatically based upon the chamber in use on the screen.
These labels can later be adjusted by the user if the decision is made to
use one physical connection to test other chambers (for example, using
only the RV connection to test RA, RV, and LV leads).
•
PSA connector clips.
Do not clip any PSA connector directly to the skin,
pocket, or other tissue of the patient.
•
Ventricular Sensing.
During a PSA session, ventricular sensing behavior
is driven by the most recently selected ventricular pacing configuration:
RV-only, LV-only, or Bi-V.
•
At system startup, the PSA mode is set to ODO (non-pacing) and the
effective ventricular pacing configuration is Bi-V.
•
When a non-pacing mode (ODO or OVO) is selected from the mode
palette, sensing is set to Bi-V to ensure sensing is enabled on both
leads regardless of any prior configuration.
•
ECG cable open/short.
Loss of the ECG signal in case of an ECG cable
open/short can affect diagnosis and screening by prolonging the
procedure or preventing the procedure from completing.
•
Check cables first and replace if cracked or worn.
•
If cable is not functioning properly, replace it.
•
Model 6689 Power Adapter.
The power adapter normally gets warm
when it is in use or charging. Do not place the power adapter in the storage
pocket of the stand while it is in use or charging as the confined space will
not allow the heat to dissipate adequately.
•
Ethernet.
If desired for use, connect the Ethernet cable only to the RJ45
Ethernet port connector on the Model 3300 Programmer. Insertion or
removal of the Ethernet cable during operation may affect networking
functions. The RJ45 Ethernet connection on the Model 3300 Programmer
is for Local Area Networking (LAN) use only. It is not to be used for a
telephone connection.
