Battery Monitoring
All TRIA
®
II Doppler units perform continuous battery monitoring and give a visual indication
of battery level. Display units use a multiple level battery shaped indicator that indicates
the voltage level of the battery. The battery outline will flash when the battery level is very
low, indicating that the user should change the batteries soon after the current examination
is complete.
Non-display units (TR150) use the On/Off LED as a battery indicator by flashing at a low
rate (approximately once per second) when the battery level is low. Several exams can
still be performed in this state of operation. The battery indicator will flash at a higher
rate (approximately twice per second) when the battery level is very low. The user should
change the batteries soon after the current exam is complete
Maintenance and Cleaning
Warnings
• The TRIA
®
II is not designed for liquid immersion. Do not soak the Doppler main unit
or probes in liquids. Use only spray or wipe cleaners and disinfectants.
Do not use
products containing bleach.
• The TRIA
®
II is not designed for sterilization processes such as autoclaving, gamma
radiation or hydrogen gas.
• The TRIA
®
II is not intended to be used on open skin. If there is evidence of open
wound contamination, disinfect the probe before using again as described below.
The TRIA
®
II Doppler requires very little maintenance. However, it is important to the
continuing function of the unit and the health of the patients that the unit is cleaned and
examined regularly per the following guideline:
After every examination:
Excess gel should be wiped off prior to docking the probe. Probes and main unit should
be cleaned with a damp cloth using warm water or presaturated isopropyl alcohol wipes
or spray. In particular, pay close attention to clean the seams along the plastic lines at the
probe face but
do not allow water or spray to enter through the connectors or speaker
grill.
To disinfect unit, use commercially available spray or wipe disinfectants registered with
the EPA. Clorox
®
Broad Spectrum Quaternary Disinfectant is the only disinfectant that is
CooperSurgical approved for use with the TRIA
®
II product. Follow the manufacturer’s
instructions and wipe unit until it is dry of solutions. Examiners should wash hands and
change gloves after every exam. Refer to local and hospital policies for cleaning and
disinfection policies.
Store unit in a clean area free from dust and debris. Follow temperature and humidity
guidelines as specified at the end of this manual.
Warning
• If the unit is to be stored for longer than 90 days without use, remove the batteries prior
to storage.
Periodically (at least annually):
Inspect the main unit and probes for signs of cracks or breaks in the mechanical housing.
Inspect cables and connectors for signs of wear or failure. The user should discontinue use
of the unit with any sign of loss of housing integrity. Contact CooperSurgical for service.
It is recommended that rechargeable batteries be replaced annually.
