0MAINTENANCE
Upon final installation of the Series RHP-W Temperature/Humidity/Dew Point
Transmitter and the companion receiver, no routine maintenance is required. A peri-
odic check of the system calibration is recommended. Except for sensor replace-
ment, t he Series RHP-W is not field serviceable and should be returned if repair is
needed (field repair should not be attempted and may void warranty). Be sure to
include a brief description of the problem plus any relevant application notes.
Contact customer service to receive a return goods authorization number before
shipping.
