An icon on the Main Window indicates the approximate

remaining power of the batteries. This battery gauge is

most accurate with the typical voltage drop across the

life of alkaline batteries.

Rechargeable batteries give little or no warning when

nearing depletion. If you use rechargeable batteries

in the transmitter, we recommend trying fully charged

batteries first, noting the length of time that the batter-

ies will run the unit, and in the future using somewhat

less than that time to determine when the battery

needs to be replaced. The Venue and other receivers

from Lectrosonics offer a timer function to assist in this

process.
