Cautions & Recommendations
To prevent possible hearing damage, do not listen at high volume
levels for long periods.
Disposal
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!
2005-08-13
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 Sync Function
What is ACT ?
L R EQ
GR CH MIC
02 03 520.500MHz
1. ACT is short for Automatic Channel Targeting. ACT is a proprietary sync technology
developed first by MIPRO in the professional audio industry. Consequently, ACT sync
has become an industry-standard for fast, easy and precise frequency
synchronization between transmitter and receiver.
A. Operating Instructions:
a. Press to exit and return to the main LCD screen.
Features
1. Frequency do not require an external tool for adjustment.
2. Precise and fast synchronization.
3. Frequency is synchronized and saved and ready for repeat usage.
Operating Instructions?
1. Press the ACT sync button on the rack transmitter to start the synchronization.
2. ACT SYNC word with moving “….” appears on the rack transmitter screen.
3. Align the ACT sync windows of both receiver & transmitter within 30cm.
4. ACT SYNC word with moving “…”disappears during a successful sync and returns
back to main LCD screen.
5. ACT FAIL appears during a failed sync.
6. Repeat step 1 to 5.

2. Up to 64 transmitters can be linked and connected.
** During ACT sync, the frequency is synchronized from transmitter to receiver.
Other setting as an encryption key (SCROLL or STATIC) is also synchronized
during the transfer.
3. Up to 300 meters of internet connection is possible. However, we recommend for up
to 100 meters to ensure optimal performance and quality of high-speed
transmission.

Rackmount Kit
Cautions & Recommendations
Rack-mounting a 1/2 rack unit
Rack-mount with an optional FB-71 rack-mount kit and fasten accordingly.
Do not use the same frequency bands when mixing MIPRO IEM and MIPRO wireless
microphone systems to avoid potential interferences.
When using RG-58 or 3D cable, do not exceed 5 meters and use 50Ω coaxial cable to
transmit signals to the external antenna.
If possible, maintain line-of-sight between transmitter and receivers for optimal
reception quality during outdoor or indoor performances. Indoor reception quality tend
to degrade due to obstacles and objects absorbing radio waves making the reception
distance shorter compared with outdoor performances.
Power supply voltage should not be less than 12V and not higher than 15V. Ensure at
