LCD Screen

The LCD is a numeric-type Liquid Crystal Display with screens for adjusting
power, frequency, audio level and low frequency audio roll-off. The transmit-
ter can be powered up with or without the RF output turned on. A countdown
appears in the LCD when powering on and off, allowing the transmitter to be
turned on without RF for adjustments, and to prevent accidentally turning it off
with momentary button presses.

Power LED

The PWR LED glows green when the battery is good. The color changes to
red at a midpoint of the runtime as the battery voltage drops. When the LED
begins to blink red, there is usually less than 30 minutes remaining with a
lithium battery.
The exact point at which the LED turns red will vary with battery brand and
condition, temperature, and the output power setting. The LED is intended to
simply catch your attention, not to be an exact indicator of remaining time. The
illustration below depicts typical behavior with a lithium battery in the single
battery model at 50 mW.

Hours
A weak battery will sometimes cause the PWR LED to glow green immediate-
ly after the transmitter is turned on, but will soon discharge to the point where
the LED will turn red or the unit will turn off completely.
