Service
Repair
Repair must be performed by Welch Allyn authorized personnel. Failure to do so
invalidates the warranty. A moderate fee is charged to calibrate the Handle after a repair.
Contact Customer Service in your region for service options.
Calibration
Welch Allyn recommends that the Handle be calibrated annually. Arrangements may be
made by returning the registration card or by contacting Welch Allyn's Technical Service
Department or an authorized Welch Allyn distributor. A moderate fee is charged for
calibration.
A monthly functional check using the MicroTest Cavity is recommended in addition to
annual calibration.
The Printer/Charger does not require calibration.
