0BMTP30 QUICK USER GUIDE
MTP30 is a professional pocket transmitter especially designed for broadcast/high quality
applications.
1. 1BOPERATION
MTP30 is composed by a main body made up of light metal alloy.
(1) Switch to enable wireless transmission, it also indicates
the battery status and peak/mute operation (with PTT).
(2) In order to allow front visibility same colour information
on (1) is replicated with this LED.
(3) Oled display for transmitter setup
(4) <ch>, <gain> and 3 positions <selector>
(5) Battery holder
(6) Cover (to open push side buttons)
1.1 2BLED INDICATIONS
Led indication with bicolor led (red & green) on wireless power switch (1) and in front led (2):
- Wireless transmission status: green when wireless on.
- Battery status: green steady, slowly blinking (< 25%), quickly blinking (<12%).
- Modulation peek (if activated): red.
- Ptt status: red if active (push to talk “pushed”).
1.2 3BBATTERIES
MTP30 is working with 2 AA alkaline or NiMH batteries (select correct type on setup controls).
Battery status can be checked on internal OLED display or looking to LED status on power
switch (see 1.1).
1.2.1 6BUBATTERY SUBSTITUTION
•Open transmitter cover and insert batteries following polarity indicated.
1.3 4BPOWERING UP
Move the wireless power switch (3) in “I” position to activate wireless transmission: a green
LED lights up (blinking when battery is low! See 1.1)
Turn on wireless:
Move the Wireless power switch in
“I” position: switch becomes green
(red indicate PTT/MUTE).
A green blinking gives you
indications on battery status.
Open MIC Body:
Push the side buttons and flip down
the cover, to access internal setup
controls and batteries.
Front LED color is
the same of
power switch.
