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!
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!

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. 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. GR CH 02 03 L R EQ AF LINE 520.500MHz L

Connect REMOTE OUT to REMOTE IN of another transmitter for interconnection of other transmitters. First transmitter (TX) 1, connect REMOTE IN to a MIPRO-DV. 2. Up to 64 transmitters can be linked and connected. 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. 26 27 Digital Stereo Rack Transmitter Digital Stereo Rack Transmitter Rackmount Kit Rack-mounting a 1/2 rack unit
! Rack-mount with an optional FB-71 rack-mount kit and fasten accordingly. Cautions Recommendations
! 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 50 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 least 500mA or more output current. Deficient current causes operating voltage instability or malfunction and exceeding current causes shorter the product life cycle and possible short or damaging circuits. Rack-mounting two 1/2 rack units side-by-side
! Remove top & bottom screws.
Insert top and bottom plates to joint two transmitters. Fasten screws.
! Rack-mount with an optional FB-72 rack-mount kit. Note
Refer to actual product in the event of product description discrepancy. Frequency range and maximum deviation comply with the regulations of different countries. 28 29
