Section 4: Device Maintenance
Inspection and Cleaning
Routine inspection will help maintain the safety and performance of your VX3+ HRV recorder.
Before operating the device perform a visual inspection to identify any worn, broken or missing
parts, and repair or replace as necessary.
The outside surfaces can be cleaned with a mild soap and water solution.
Do not dispose of unit in trash. Dispose of as the Waste Electrical and Electronic Equipment
(WEEE) regulations for your area require.
Caution
:
DO NOT IMMERSE THE DEVICE IN LIQUID!
Caution:
DO NOT CLEAN THE PATIENT CABLES WITH ALCOHOL. DO NOT
AUTOCLAVE THEM, OR USE ULTRASONIC CLEANERS.
Caution:
DO NOT USE ANY HARSH CHEMICALS SUCH AS ACETONE,
CHLORINE BLEACH, AMMONIA, OR IODINE TO CLEAN THE VX3+.
Testing
The VX3+ executes a power-on self check when the battery is inserted. Any errors in the unit’s
subsystems will be reported with an appropriate error message. Following the instructions on the
screen and then removing and replacing the battery can remedy most errors. A blank display
indicates a discharged battery or a malfunctioning device. If error messages persist contact your
CAIRD TECHNOLOGY INC. service representative. Except for battery and SD card replacement,
there are no user serviceable parts in the VX3+. The unit must be returned to CAIRD
TECHNOLOGY INC. for service. The VX3+ may also be tested by attaching the patient leads to a
commercially available ECG simulator and verifying each lead has amplitude and morphology as
described in the simulator’s manual. Excessive artifact usually indicates the patient cable needs
replacing. Use only replacement cables purchased from CAIRD TECHNOLOGY INC..
Battery Maintenance and Precautions
Use only AA Alkaline Batteries (IEC-LR6). Use of another battery may present a risk of short
recordings, device damage, or malfunction. Remove batteries from VX3+ unit promptly when
depleted. Never store a battery in the recorder.
