16. CHARGING THE REDMIKE VC
Before using, the REDMIKE VC should be charged. It will take 8-9 hours for the
REDMIKE VC to obtain a full charge. A fully charged REDMIKE VC will last for
over 7 hours of use. If microphones are used daily, they should be kept in the
charging 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 VC 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 VC 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 VC is
turned OFF.
3. Place the REDMIKE VC into the
cradle. The LED on the cradle
will glow RED indicating charging
has started. When the REDMIKE
VC is fully charged the LED on
the cradle charger will change to
GREEN.
17. SETUP & OPERATION OF REDMIKE VC
Once the REDMIKE VC is charged, follow these steps to set it up for use.
1. Turn the CAT AV power on. The
power LED on the aplifier will
glow.
2. Remove the REDMIKE VC from the
charging cradle and turn it on.
3. Slip the REDMIKE VC with lanyard
around the neck and position the
top of the microphone just below
the collarbone. NOTE: Positioning
of the REDMIKE VC is critical for
proper volume adjustment.
NOTE: A nominal volume level
must be set on the CAT 885 before
adjusting controls on the REDMIKE
VC.
The teacher can now use the
controls on the REDMIKE VC
to adjust the volume level from
anywhere in the room. The
microphone volume control has 4
steps up and 4 steps down from
the mid point (9 levels total).
4. While speaking in a normal voice
slowly increase the volume of the
corresponding channel on the
CAT AV until your voice is barely
audible. Each REDMIKE VC has its
channel pre-set to either A or B, as
indicated on the back of the Mic.
5. Once initial volume level is set,
walk around the room and listen
for audio dropout and overall
audio quality.
6. If a second REDMIKE VC was
purchased, repeat steps 2-4.
