Before operation, please check and make sure that transmitter & receiver are of
matching channels.
To switch on the microphone, put the switch to "ON" position. The red LED indicator will
light briefly indicating that battery is fresh. When the RED LED light is steady, it indicates
that battery is weak, thus a replacement is necessary.
For best results, an alkaline battery is recommended. Please remove the battery if the
transmitter is not to be used for a longer period.
When necessary, the MW165U microphone capsule can be replaced by pulling out and
plugging in the new one.
For close singing or speaking, put the sensitivity switch to N (Normal) and for mic stand
applications or when the speaker stands away
, put the sensitivity switch to
H (High). Be careful to put back the sensitivity switch to N for close singing as H (High)
sensitivity for close vocal applications may cause distortion.
When holding the handheld microphone, please do not hold the antenna end of the unit
for it will severely affect the efficiency of the transmission range.
