User Manual

Power Module

The Charger Base requires 5VDC 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 will result

in shorter run times. This is normal. Always return microphones to the Charger Base when not in use.

Important: The Lithium Polymer rechargeable batteries that power the microphones were released

with both replaceable and non-replaceable type batteries. To distinguish between the 2 different

type versions is by serial number only. Serial numbers are located on the label of the back of the

microphone itself. Any serial number preference starting with either 7010 or 8020 are equipped with

current replaceable rechargeable Lithium Polymer type batteries. If the serial number preference is

anything else but 7010 or 8020 Please contact Yamaha Unified Communications, Inc. at

www.uc.yamaha.com or your AV service provider for replacement instructions for returning and

servicing non replaceable type microphone batteries. For replaceable type battery microphones,

with serial number preference starting with either 7010 or 8020, replace only with the same

manufacturer and model battery type recommended by Yamaha Unified Communications, Inc..

Please contact Yamaha Unified Communications, Inc. at www.uc.yamaha.com or your AV service

provider for correct manufacturer approved and recommended replacement type batteries or process

for return and replacement for either type battery.

Caution: Risk of explosion if batteries are mishandled or replaced by an incorrect type. Do not disassemble

batteries or attempt to charge outside the system. Do not dispose of batteries in fire. Dispose of batteries in

accordance with manufacturer’s instructions and local regulations.

Either a solid RED LED (charging) or solid GREEN LED (100% charged) will appear to confirm

that the microphone is inserted properly in the Charger Base. The microphones are not transmitting

audio to the HD Base Station while in the Charger Base. In normal use, batteries should fully

charge in about 2 hours, but will “quick-charge” to 80% capacity in approximately 1 hour and 20

minutes. Fully charged microphones left in the Charger Base remain solid GREEN.

Updating the Revolabs HD

Revolabs HD

Systems are field upgradable for the firmware portion of the Base Station
