Features
Battery Status LED Indicator
AA batteries can be used to power the transmitter. 
The LED labeled BATT on the keypad glows green 
when the batteries are good. The color changes to red 
when the battery voltage drops down and stays red 
through most of the battery life. When the LED begins 
to blink red, there will be only a few minutes remaining.
The exact point at which the LEDs turn red will vary 
with battery brand and condition, temperature and 
power consumption. The LEDs are intended to simply 
catch your attention, not to be an exact indicator of 
remaining time.
A weak battery will sometimes cause the LED to glow 
green immediately after the transmitter is turned on, but 
it will soon discharge to the point where the LED will 
turn red or the unit will turn off completely.
Some batteries give little or no warning when they 
are depleted. If you wish to use these batteries in the 
transmitter, you will need to manually keep track of the 
operating time to prevent interruptions caused by dead 
batteries. 
Start with a fully charged battery, then measure the time 
it takes for the Power LED to go out completely.
NOTE: The battery timer feature in many 
Lectrosonics receivers is very helpful in measuring 
battery runtime. Refer to the receiver instructions 
for details on using the timer.
Menu Shortcuts
From the Main/Home Screen, the following shortcuts 
are available:
•  Record: Press the MENU/SEL + UP arrow simulta-
neously
•  Stop Recording: Press the MENU/SEL + DOWN 
arrow simultaneously
NOTE: The shortcuts are only available from the 
main/home screen AND when a microSDHC 
memory card is installed.
IR (infrared) Sync
The IR port is for quick setup using a receiver with this 
function available. IR Sync will transfer the settings for 
frequency, step size and compatibility mode from the 
receiver to the transmitter. This process is initiated by 
the receiver. When the sync function is chosen on the 
receiver, hold the IR port of the transmitter near the IR 
port of the receiver. (There is no menu item available on 
the transmitter to initiate the sync.)
NOTE: If a mismatch exists between the receiver 
and transmitter, an error message will appear on 
the transmitter LCD stating what the problem is.
