4. CHARGING THE REDMIKE
Before use, the REDMIKE should be charged. It will take 8-9 hours for the 
REDMIKE to obtain a full charge. A fully charged REDMIKE will last for over 7 
hours of use. If microphones are used daily, they should be kept in the cradle – 
microphones can be left in a charging cradle constantly for up to 2 weeks without 
causing degradation to battery life. 
A red light on the charging cradle indicates the REDMIKE is charging. A green 
light indicates that charging is complete and a full charge has been reached. A 
blinking light indicates a charging or sensing error. See Troublshooting section 
for more information.
REDMIKE incorporates alkaline protection into the microphone design. Always 
use a Lightspeed rechargeable sensing battery. Replacement AA NiMH batteries 
may only be purchased through Lightspeed Technologies (part # BA-NH2A27). 
Do not attempt to charge alkaline batteries. They can overheat and expand 
creating a significant hazard and damaging the microphone (this is not covered 
by warranty).
1.  Plug power cord into the cradle 
charger and then plug the AC end 
into an electrical outlet.
2.  Ensure that the REDMIKE is turned 
OFF.
3.  Place the REDMIKE into the 
cradle. The LED on the cradle 
will glow RED indicating charging 
has started. When the REDMIKE 
is fully charged the LED on the 
cradle charger will change to 
GREEN.
