Lectrosonics MM400a - QSG - Manual

Water-resistant transmitter
Users Quick Guide
If you are using the MM400 in a wet environment (immersion, perspiration, rain scenes etc) - be certain all O-rings are intact
and that a waterproof mic connector (from Lectrosonics, properly installed and sealed) is used on the microphone cable.
WARNING! TO PREVENT WATER DAMAGE or INTERNAL CORROSION!
If the transmitter is wet (either due to immersion or high levels of perspiration), DO NOT OPEN any covers or
connectors. BEFORE OPENING, carefully blot the transmitter dry with a clean paper towel or cloth. Remove all
visible signs of moisture and tap the transmitter on a soft surface such as your hand to shake any retained
mositure loose from under the O-rings. After opening any connector or cover, carefully blot up any remaining
moisture that may have remained around the seal or fallen into the threads. THIS IS IMPORTANT! DO NOT
CLOSE ANY COVER OR CONNECTOR BEFORE MAKING CERTAIN THERE IS NO MOISTURE IN OR NEAR
THE OPENING. After use, it is critical to store the transmitter in a dry place with all covers and connectors
opened to allow any internal humidity to evaporate. Do NOT store wet or sealed up.
A standard 2.5mm tip/sleeve connector can be used with most positive bias lavalier microphones if water protection is not
necessary. DO NOT IMMERSE if the water resistant connector provided by Lectrosonics is not used.

been in a high water environment - see the warning above for
storage instructions.
To set the mic level - turn the level

Power output 100mW.
Battery life Expected battery life is approximately 5 hours with a AA lithium cell, 1.5 to 2 hours with a alkaline cell
at 72 deg F or higher. Rechargeable NiMH can also be used - expect approximately 2-2.5 hours from a
1700mAh NiMH battery.
Battery AA - Lithium recommended - rechargeable NiMH or Alkaline are also acceptable but battery life will be
shorter. Alkaline batteries will not work well at low temperatures.
