Caution Statements
The following equipment cautions appear in the text whenever the
equipment is in danger of damage and are repeated here for emphasis.
Safety Statements
USAGE
ANY USE OF THIS INSTRUMENT IN A MANNER NOT
SPECIFIED BY THE MANUFACTURER MAY IMPAIR THE
INSTRUMENT’S SAFETY PROTECTION.
CAUTION
The interface module contains electrostatic discharge (ESD)
sensitive components. Failure to observe ESD precautions can
cause permanent damage.
CAUTION
Changing the sensor’s connectors will invalidate calibration data, and
may reduce the maximum power rating of the unit.
CAUTION
Ensure that the 115/230 voltage selector on the 4421’s rear panel is set
to the proper voltage before ac power is applied.
CAUTION
The Bird 4421 must be powered off when connecting or
disconnecting the power sensor from the power meter.
CAUTION
Do not use the power sensor with a load VSWR greater then 2:1.
Damage to the power meter, power sensor, or the
RF power source could occur.
CAUTION
During remote operation, periodically monitor the bus
service request line. Failure to detect a service request
could result in equipment damage.
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.
