Before Calling for Service
Before calling for service on a transmitter that may appear to be
operating incorrectly or to have failed, check the following:
Transmitter
Frequent Lead Fail
Events
•
Swap the leadwire set with either a new set or a known good set.
Leadwires may have hidden internal damage that can cause signal
failure.
•
Leadwires may become brittle or damaged after frequent cleanings.
They should be inspected before each use and replaced if damaged.
•
Leadwires that have been wrapped around the transmitter when not
in use are more likely to be damaged. Leadwires should be either laid
out flat or hung up such that there are no kinks or sharp bends in the
wires.
•
Check the electrodes on the patient. Improper preparation can cause
Lead Fail events.
•
Should Lead Fail events continue to occur regularly a call for service
may be necessary.
Short Battery Life
•
Install a fresh set of alkaline AA batteries into the transmitter and
then verify battery life.
•
Once used in a transmitter for any length of time, used batteries
should be disposed of (recycled) immediately.
•
Batteries must not be re-used. Batteries should be used for only one
patient. Do not store used batteries for use with the next patient. A
battery contains a finite amount of stored energy. Each unit of time a
battery is used diminishes the amount of stored energy. Installing a
used battery in a transmitter results in a greatly reduced, and
unpredictable, monitoring period.
•
Never use a battery beyond the recommended expiration date for the
battery. The amount of stored energy in the battery may not be
sufficient for proper monitoring.
•
Rechargeable batteries should not be used. The transmitter circuitry
and the Accutracker were designed for the power output
characteristics of alkaline batteries.
NOTE
Rechargeable batteries do not store as much energy as
alkaline batteries and have very different output
characteristics. The monitoring period may be greatly
shortened and the specified low-battery warnings may be
adversely affected or possibly not even displayed.
