Operating Instructions

Battery Status LED Indicators

Alkaline, lithium or rechargeable batteries can be 

used to power the transmitter. The type of batteries 

in use are selectable in a menu on the LCD.
When alkaline or lithium batteries are being used, 

the LED labeled BATT on the keypad glows green 

when the batteries are good. The color changes to 

red when the they are nearing the end of 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 LEDs 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.
Rechargeable batteries give little or no warning when 

they are depleted. If you wish to use these batter-

ies in the transmitter, you will need to manually keep 

track of the operating time to prevent interruptions 

caused by dead batteries. Many Lectrosonics receiv-

ers have a timer function to keep track of battery 

runtime.
The Power/Function LED on the top panel will mirror 

the keypad LED unless the programmable switch is 

set to the Mute or Talkback mode, and the switch is 

turned on.

NOTE: The battery timer feature in many 

Lectrosonics receivers is very helpful in 

measuring battery runtime when using 

rechargeable batteries. Refer to the receiver 

instructions for details on using the timer.

Powering On in Operating Mode

Press and hold the Power Button   for several 

seconds until a counter on the LCD progresses from 

1 through 3, followed by a display of the model, 

firmware version, frequency band and compatibility 

mode.
