Chapter 5 Maintenance
This chapter describes routine maintenance, along with troubleshooting instructions for the power meter and
power sensor. Disassembly instructions for the Bird Cal Cart are also provided. For service beyond this level, return
the unit to a qualified service center
The Bird 4421 Power Meter requires only simple, routine maintenance.

Wipe off dust and dirt regularly.

Check the connectors and cables for damage.

Clean the connector contacts with alcohol or dry cleaning solvent.
Troubleshooting
Since the power meter and power sensor can only work together, the first step is to determine which is malfunction‐
ing. Connect the power sensor to the meter and perform the functional test on page 13. If the power meter is mal‐
functioning, refer to the troubleshooting table below. If the power sensor is malfunctioning, return it for service.
This manual cannot list all malfunctions that may occur, or corrective actions. If a malfunction is not listed or is not
corrected by the listed corrective actions, contact a qualified service center.
Note: For all power sensor tests, following the test procedure will check the sensor not covered by the
safety cover. To test the other sensor slide the safety cover over, then proceed as normal.
WARNING
To avoid personal injury, disconnect the power cord from the AC line before performing any maintenance,
including fuse replacement.
WARNING
Never attempt to connect or disconnect RF equipment from the transmission line while RF power is being
applied. Leaking RF energy is a potential health hazard.
WARNING
The Bird 4421 contains no user‐serviceable parts. Do not remove its cover.
CAUTION
Due to the complexity of the Bird Power Sensor, field repairs beyond general maintenance should not be
attempted. Removal or disturbance of the power sensor cover can result in cancellation of lifetime warranty.
