Special Lifetime Warranty –
Series 4020 Power Sensor Head
In addition to its standard warranty, the Bird Electronic Corporation warrants its
Series 4020 Thruline® Power Sensor Heads for lifetime to original purchaser. This
extended warranty is against burnout. For the warranty to apply, the Sensor Head
must be used with the correct Bird Electronic Corporation Display Unit, the maximum power rating of the Sensor must not be exceeded, the Sensor RF circuit must
be properly terminated and the Sensor not subjected to physical abuse.
Bird Electronic Corporation, at its option, will repair or replace the defective
Sensor at its world Headquarters at 30303 Aurora Road, Solon, Ohio 44139.
The customer is responsible to pay transportation charges to return the defective sensor to Bird.
