which are indoors, especially basements, or structures, which are concrete and steel. It may be
possible to remotely locate an external antenna whenever poor Pro Max receiver locations exist.
Call Rain Master Technical support for assistance, telephone (805) 527-4498. Moving the Pro
Max transmitter to a more favorable location or usage of optional high gain antennas on both the
Pro Max transmitter and Pro Max receiver may improve operations.
The Pro Max system utilizes VHF/FM communications and the Pro Max receiver/Pro Max
transmitter pair is factory encoded to insure that other services including other Rain Master
remotes do not interfere or false trigger the Pro Max receiver. Digital filtering further enhances
operation in interference prone environments. FM transmission is employed for its inherent
quality and immunity to atmospheric, static, and electrical interference which are commonly
found in AM types of equipment such as citizen’s band radio, garage door openers, etc. Usage of
FM transmissions also insures that the stronger signal prevails (capture ratio), meaning that all
received signals, which are weaker than the Pro Max transmission, are completely overridden.
Note: Antennas are not just a piece of wire; they are cut for a precise frequency of
operation in order to ensure optimal performance. When using antennas with the
Pro Max system, only utilize Rain Master specified parts, which are available
through your authorized Rain Master distributor.
