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.
Important: Do not open or try to modify any of the batteries delivered with the Revolabs HD
microphones. The latest releases of the Revolabs HD microphones include field replaceable
batteries. Replace these batteries only with Revolabs approved batteries. In Revolabs HD
microphones manufactured before mid of 2012, the Lithium Polymer rechargeable batteries that
power the microphones may not be user replaceable. To determine whether the battery is user
replaceable, identify the first digit of the serial number, and reference the table below.
