Welch Allyn 124 Propaq Encore Reference Guide
Monitor Functions Based on Battery Voltage
As battery voltage drops during extended monitor battery operation, error messages are
displayed and monitor functions are discontinued in order of priority.
Checking Battery Voltage
The Propaq’s battery voltage is displayed on the initial powerup screen. The battery voltage
is also displayed with the Settings window.
Replacing the Fuse
The Propaq Encore is protected against power surges by a 3 Ampere fuse, which can easily be
replaced in the right side panel. Fuse replacement should only be performed by a qualified
service person.
1. Disconnect the Propaq Encore from the patient.
2. Disconnect the ac power adapter from the
Propaq Encore’s power input connector.
3. Using a small screwdriver or similar device,
unscrew the fuse carrier by turning it
counterclockwise.
4. Remove the fuse holder and replace the fuse
with a 3 Ampere, 2AG, 250V (fast or slow
acting) fuse. This fuse can be ordered from Welch Allyn or its service centers using
part number 503-0058-00.
If the green Battery Charging lamp does not light when an ac adapter is
connected, this fuse may be blown.
