Power Module

The Charger Base requires 9-24VDC power, provided by the AC Adapter. Plug the supplied AC

adapter into an appropriate power outlet 110-240 AC, 50-60Hz. The power LED on the Charger Base

will illuminate.

Charging the Microphone Batteries

First-time use — Before using the wireless microphone the first time, charge the batteries in the

microphones for eight hours (or overnight) in the Charger Base.

Recharging — When the YELLOW LED starts to flash intermittently on the microphone the battery

has 30 minutes of charge remaining. Over time (years), batteries gradually wear down and require

longer charging times. This is normal. Always return microphones to the Charger Base when not in

use.

microphones. The latest releases of the Revolabs HD microphones include field replaceable

batteries. Replace these batteries only with Revolabs approved batteries. In Revolabs HD
