General maintenance
CAUTION A defective screener should not be used. Confirm that all
connections to external accessories are seated and secured properly. Parts
which may be broken or missing or are visibly worn, distorted, or
contaminated should be replaced immediately with clean, genuine
replacement parts manufactured by or available from Welch Allyn.
The screener requires no regular maintenance beyond routine cleaning and annual
calibration. Replace the probe tube if it becomes clogged.
The screener is not user repairable. Repairs and battery replacement must be performed
only by a qualified Welch Allyn service representative.
Annual calibration is recommended. An authorized service technician should perform
electrical safety checks in order to maintain continued compliance with IEC and UL
60601-1.
Replace the probe tube
Probe tubes are disposable and should be replaced when they become clogged.
Replacement probe tubes are included with the screener.
1. Grasp the probe head with the fingertips of one hand.
2. Use the eartip to grasp the clear, plastic probe tube with the fingertips of your other
hand.
3. Twist the probe head slightly while pulling the eartip and probe tube straight out of
the probe head.
4. Dispose of the used probe tube immediately to avoid confusing used tubes and new
tubes.
5. Insert a new probe tube into the probe head until it is fully seated.
A properly inserted probe tube snaps securely into place when it is fully seated in the
probe head.
CAUTION Do not attempt to clean probe tubes. This may
cause damage to the probe head.
