Disposal

200 5-08- 13

Dispose of any unusable devices or batteries responsibly and in
accordance with any applicable regulations.

Disposing of used batteries with domestic waste is to be avoided!

Batteries / NiCad cells often contain heavy metals such as cadmium(Cd),
mercury(Hg) and lead(Pb) that makes them unsuitable for disposal with
domestic waste. You may return spent batteries/ accumulators free of
charge to recycling centres or anywhere else batteries/accumulators are
sold.

By doing so, you contribute to the conservation of our environment!

MIPRO'S PROPRIETARY "ACT" FUNCTION & OPERATION

What is ACT?

“ACT” stands for “Automatic Channel Targeting”. MIPRO was the first manufacturer in
the industry to use infrared (IR) technology to automatically synchronize the frequency
selected on the receiver to any ACT handheld or bodypack transmitter on the same
frequency band.

ACT Features

!

No manual frequency adjusting needed, unlike traditional transmitters.

Simple, fast and precise frequency set-up without mechanical errors.

!

Once the frequency has been set, the data is stored in memory, meaning that the

!

frequency is set until it is changed by performing the “ACT” function again, even
after powering off.

ACT Set-Up

! Ensure a receiver channel is set up.

! Press and release the “ACT” button to activate the ACT function. Once activated,

the word “ACT” appears.

! Locate the transmitter infrared (IR) port and bring it within 30cm (12”) of the

receiver's ACT port. The receiver's IR port is a round “window” located between the
ACT & SET buttons. The transmitter IR port is normally indicated by a round red
colored spot.

! When the frequencies are synchronized successfully between the transmitter and

receiver, the word “ACT” disappears and the original group and channel reappears.
