Disposal

2005 -08-1 3

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 developed and patented this
innovative infrared (IR) sync technology in 2001. MIPRO was the first manufacturer in
the industry to automatically synchronize the frequency selected on the receiver to any
ACT handheld or bodypack transmitter on the same frequency band.

ACT Benefits:

!

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 and transmitter batteries are fresh, installed
correctly and powered-on.

!

Press the ACT button on the receiver to activate the ACT syncing function. Once
activated, the group/channel and working frequency start blinking.

!

Bring ACT handheld or bodypack transmitter within 30cm (12”) of the IR port on the
receiver. The IR port is located between the 'ACT' and “▼” buttons and indicated by
a round-shaped red color spot. The frequency will sync automatically.

!

When the frequencies are synchronized successfully between the receiver and
transmitter, the RF meter cursor and working frequency stop blinking and the
indicators in the RF meter are lit.
