CONTROLS AND FUNCTIONS
MIC
The input accommodates virtually every lavaliere, hand-held or shotgun microphone available. Line level signals can
also be accommodated. Use a Switchcraft TA5F connector on the cord. (See 5-Pin Input Jack Wiring.)
POWER ON/OFF SWITCH
Turns the transmitter on and off. A pilot tone muting system prevents “thumps” or transients from occurring even if
the transmitter is abruptly switched on or off.
POWER LED
Glows green when the LM transmitter is operating and the battery is good. Turns red when the battery voltage drops
to 6.1 VDC. Starts blinking red when the voltage is to 5.6 VDC. When using a recommended lithium or alkaline
battery, there will be about 30 minutes of operating time remaining when the Power LED first begins blinking red.
Note
A weak battery will sometimes cause the Power LED glow green, but it will soon discharge to the
point where the Power LED will glow red or go out completely. If in doubt, replace the battery
with a known new battery prior to starting the program. If the Power LED fails to glow when the
LM is turned on, replace the battery.
A NiMH batteries give little or no warning when they are depleted. If you wish to use NiMH batteries in the LM
transmitter, you will need to manually keep track of the operating time. Start with a fully charged battery, then
measure the time it takes for the Power LED to extinguish. A number of Lectrosonics receivers incorporate a Battery
Timer function which track the amount of time the transmitter signal is detected (See your receiver manual to
determine is this function is available.) By using the receiver’s battery timer and replacing the transmitter battery
before the premeasured time is up, users can minimize potential loss of audio when NiMH batteries are used.
FREQUENCY SELECT SWITCHES
Two 16-position rotary Frequency Select Switches accessed through the side panel are used to adjust the center
frequency of the carrier signal. These switches are labeled 1.6M and 100K. The 1.6M switch is used for coarse
frequency adjustments and the 100K is used for fine frequency adjustment
