GENERAL TIPS FOR IMPROVING SYSTEM PERFORMANCE
1. Strive for unobstructed, line-of-sight arrangement between transmitter and receiver
antennas for best operating range. Solid metal objects, electronic equipment & digital
devices in between will usually greatly reduce range.
2. Minimize the distance as much as possible between the transmitter and receiver
antennas for improved reception and system performance.
3. Use supplied antennas and cables to preserve receive sensitivity and minimize signal
loss.
4. Fresh, high-quality alkaline batteries is highly recommended to ensure reliable
transmitter operation as weak or worn-out batteries are common cause of wireless
problems, including failure, poor range, distorted audio and interference.
5. External electrical current should exceed 500mA for MR-818 receiver and 1A for MR-
818T receiver.
6. External DC power supply should not fall under 12V, otherwise it would not work
properly. If it is over 15V, some components of the receiver will be damaged.
7. If extended reception distance is needed, installing a MIPRO AT-90W wideband dual
directional antenna, which includes internal boosters will increase the reception
distance.
8. Proper antenna distribution is vital to achieving ideal performance from multiple
wireless systems operating in the same venue. To greatly reduce antenna clutter in
multi-system installations, a MIPRO AD-707a, UHF antenna divider system is
recommended. Each AD-707a supports up to four UHF diversity receivers to operate
from a single pair of antennas. When combined with an AT-70A omni-directional
extension antenna and an AT-70B antenna booster or an AT-90W wide-band
directional antenna, the AD-707a antenna divider provides optimal signal reception
with minimal dropouts or interference.
9. See “Troubleshooting” section for wireless symptoms and possible solutions.
