Notes:
!
The portable receiver and transmitter are
equipped with a programmable automatic shutoff timer which, upon expiration will turn off.
!
The shut-off timer is pre-programmable with
MIPRO PC interface software and is currently
factory set for a duration of 6 hours (360
minutes).
!
Thirty (30) seconds before the shut-off timer
elapses a TIME OUT message will appear on the
LCD screen and then it will be powered off
automatically to conserve the battery.

General Tips for Improving System
Performance
1. Performer should avoid holding the microphone over
or near the antenna section as this will deteriorate
transmission efficiency. Severe deterioration if
performer directly covers up the antenna section with
both hands.
2. Many performers tend to hold the microphone by the
top grille. Unfortunately, this position seriously
degrades both the sound quality and directionality of
a microphone. Even the most expensive microphones
will have its original sound quality compromised by
this method. Grabbing a microphone by the grille will
isolate the capsule's acoustic resonance circuit and or
change the capsule resonator's frequency. This
results in an inferior performance in both frequency
response and the separation of directionality. In
addition, a palm's sound-focusing effect will tend to
strengthen resonances in certain frequencies and can
cause unwanted echo.
3. A proper technique is required for using directional
microphones because the distance between the
microphone and your mouth has a significant impact
on sensitivity and performance. There is an inverse
relationship between microphone sensitivity and the
distance from the mouth to the microphone.
Consequently, performers with a ''weaker'' sound
level cannot expect to hold the microphone too far
away from their mouth and compensate by turning
up the amplifier volume to increase the sound level
as this can easily cause echo or feedback. In
contrast, performers with a ''louder'' sound level
should not hold the microphone too close as this can
easily result in distortion by causing the amplifier
system to be overloaded.

4. Furthermore, a large-diaphragm directional
microphone has a very distinct proximity effect.
When the microphone is close to the mouth, the
bass response is strengthened as the distance gets
closer. Therefore, if a performer's sound is
insufficient in bass, they can hold the microphone
closer and use the proximity effect to help
compensate for the lower bass level. Conversely, if a
performer's voice is too heavy in the bass register,
increasing the distance between the microphone and
their mouth will decrease the proximity effect and
reduce the bass response, thus making their voice
become clearer and brighter.
5. It is recommended to keep the grille and sponge
windscreen clean to avoid any substance blocking the
proximity effect of the microphone.
Notes
1. Refer to actual product in the event of product
description discrepancy.
2. Frequency range and maximum deviation comply
with the regulations of different countries.

FCC Radiation Exposure Statement
Federal Communication Commission Interference
Statement
This equipment complies with FCC RF radiation
exposure limits set forth for an uncontrolled
environment. This equipment should be installed
and operated with a minimum distance of 20
centimeters between the radiator and your body.
This equipment has been tested and found to
comply with the limits for a Class B digital device,
pursuant to Part 15 of the FCC Rules. These limits
are designed to provide reasonable protection
against harmful interference in a residential
installation.
This equipment generates, uses and can radiate
radio frequency energy and, if not installed and
used in accordance with the instructions, may cause
harmful interference to radio communications.
However, there is no guarantee that interference
will not occur in a particular installation. If this
equipment does cause harmful interference to radio
or television reception, which can be determined by
turning the equipment off and on, the user is
encouraged to try to correct the interference by one
of the following measures:
!
Reorient or relocate the receiving antenna.
!
Increase the separation between the equipment
and receiver.
!
Connect the equipment into an outlet on a
circuit different from that to which the receiver
is connected.
!
Consult the dealer or an experienced radio/TV
technician for help.

Disposal Dispose of any unusable devices or batteries
Le présent appareil est conforme aux CNR d'Industrie
Canada applicables aux appareils radio exempts de licence.
L'exploitation est autorisée aux deux conditions suivantes:
(1) l'appareil ne doit pas produire de brouillage, et
(2) l'utilisateur de l'appareil doit accepter tout brouillage
radioélectrique subi, même si le brouillage est susceptible
d'en compromettre le fonctionnement.
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!
