Procedures
Charging cradle
This procedure verifies charger operation. It does not verify charger accuracy. Voltage and
current are reported on the service screens with wide tolerances, due to measurement
limitations of the monitor and limitations in how the cradle reports charging currents.
Charger voltages and currents are tested to very narrow tolerances at the factory.
Inspecting the monitor connector
Inspect the 17-pin monitor connector to verify that it is clean and free of debris.
Partially discharging the battery
With the monitor out of the cradle, run the monitor until it does a low-battery shutdown.
Charging/LED operation
1. Observing correct polarity, connect the DC input cable (008-0290-XX) to the power
supply.
2. Set the power supply for 28 VDC.
3. Connect the DC input cable from the power supply to the cradle.
4. With the monitor removed from the cradle, verify that the input current to the cradle
is less than 50 mA, the power indicator on the cradle is green, and the status indicator
on the cradle is off.
5. Disconnect the power cable from the cradle and the power supply.
6. Connect the AC power adapter (503-0142-XX) to the cradle, and verify that the power
indicator on the cradle is ON and the status indicator on the cradle is OFF.
7. Dock the monitor into the cradle, and turn on the monitor if it does not turn on
spontaneously.
8. Verify that the status indicator on the cradle is green.
9. After the monitor completes its power-up diagnostics, navigate to
