NTI VEEMUX VIDEO MATRIX SWITCH

Battery Replacement

The IRT has a low-battery indicator to let the user know when it is time to change the batteries. The right-hand decimal point in the LCD display will illuminate (see illustration below). This will stay illuminated while the IRT is in use until the batteries are changed or the battery charge is too low for the IRT to operate.

To Change The Batteries:
