MIPRO MR-823 Dual-Channel Diversity Receiver - Manual (Page 6)

! Maintain a line-of-sight between transmitter and receiver antenna. Metal objects
between the transmitter and receiver will usually greatly reduce range.
! Minimize the distance between transmitter and receiver as much as possible for optimal
reception and performance and reduce the chances of signal drop-outs.
! Mount the receiver position in a standard 19” rack as high as possible.
! Mount receiver antennas as high as feasible above the floor or stage.
! Avoid placing transmitter and receiver where metal or other dense materials may be
present.
! Use the supplied receiver antenna.
! Do not obstruct receiver antenna.
! Always operate any wireless microphone system with its antennas fully extended.
! Do not allow receiver antennas to touch each other.
! Perform a walk-through before your performance or presentation. If dead spots are
found, try moving the receiver a meter or so. If dead spots remain, simply mark these
spots and avoid them.
! Use only fresh alkaline batteries for optimal battery hours and performance. Other
types of batteries might have too low a voltage or inadequate capacity for the
transmitter to achieve full power output.
! The receiver cannot pick up signals from two transmitters at the same time.
! Turn transmitter off when not in use to conserve battery power. Always remove the
battery if the transmitter is not to be used for a period of longer than one week. If a
battery is left in, it may leak battery acid and damage the internal electronics.

TIPS FOR ACHIEVING OPTIMUM PERFORMANCE 4. Place the receiver away from noise sources like computers, cordless phones, metal
objects or other RF generating equipment such as CD players, DAT machines, and
digital signal processors.
5. To ensure best possible reception, the receiver must be installed at least 1 meter
(3.3 feet) above the ground. In addition, the distance between the transmitter and
receiver must be more than 1 meter (3.3 feet) as illustrated in Figure 6.
6. Mount the receiver(s) into an EIA-standard 19" rack as illustrated in Figure 7. To
improve antenna reception, an optional pair of FB-30, front mount antenna kit, can
be installed in the front panel.

The output voltage of the external DC power supply should not be below 12V, otherwise
it will not work properly. If the voltage is over 15V some components of the receiver
will be damaged due to excessive current draw.
