Once ACT button is pressed, it
automatically syncs the selected
receiver frequency to any MIPRO
ACT handheld or bodypack
transmitter in the same frequency
band quickly and precisely.
MIPRO'S Proprietary "ACT" Function and Operation
ACT Benefits
! No manual frequency adjusting needed, unlike traditional transmitters.
! Simple, fast and precise frequency setup without mechanical errors.
! Once the frequency has been set, the data is written to memory in the transmitter.
This ensures that the transmitter frequency now stays with that transmitter. That is,
of course, until a change is required. By performing the “ACT” function again, the
frequency can be re-programmed to another Group/Channel as necessary.
ACT Set-Up
! Ensure a receiver channel is set up, the transmitter battery is charged, and the
transmitter is powered ON.
! Press and release the ACT button on the receiver to activate the ACT sync function.
Once activated, the words “ACT” and “Sync” will illuminate.
! Move the ACT handheld or bodypack transmitter IR window to within 30cm (12”) of
the IR port on the receiver. The IR port on the receiver is located behind the “ACT”
button itself and is indicated by a round, dark red dot. The frequency will sync
automatically.
! When the frequencies have successfully synchronised between the receiver and
transmitter the illuminated “ACT” and “Sync” will disappear. The RF meter will now
illuminate and show full RF strength.
What is ACT?
“ACT” stands for “Automatic Channel Targeting”. MIPRO developed and patented this
innovative InfraRed (IR) technology in 2001. MIPRO was the first manufacturer in the
industry to automatically synchronise the frequency selected on the receiver to any ACT
handheld or bodypack transmitter in the same frequency band.
