that produce heat.
9. Do not defeat the safety purpose
of the polarized or grounding-
type plug. A polarized plug
has two blades with one wider
than the other. A grounding-
type plug has two blades and
a third grounding prong. The
wide blade or the third prong is
provided for your safety. If the
provided plug does not fit into
your outlet, consult an electrician
for replacement of the obsolete
outlet.
10. Protect the power cord from
being walked on or pinched
particularly at plugs, convenience
receptacles, and the point where
they exit from the apparatus.
11. Only use attachments/
accessories specified by the
manufacturer.
13. Unplug this apparatus during
lightning storms or when unused
for long periods of time.
14. Refer all servicing to qualified
service personnel. Servicing is
required when the apparatus
has been damaged in any way,
such as power-supply cord or
plug is damaged, liquid has been
spilled or objects have fallen into
the apparatus, the apparatus
has been exposed to rain or
moisture, does not operate
normally, or has been dropped.
15. When the mains plug or
appliance coupler is used as the
disconnect device, it shall remain
readily operable.
16. Please keep the unit in a good
ventilation environment.
17. WARNING: To reduce the risk
of fire or electric shock, do not
expose this apparatus to rain or
moisture.
18. Apparatus shall not be exposed
to dripping or splashing and no
objects filled with liquids, such
as vases, shall be placed on the
apparatus.
19. Warning - battery pack shall not
be exposed to excessive heat
such as sunshine, fire or the like.
12. Use only with a cart,
stand, tripod, bracket or
table specified by the
manufacturer, or sold with
the apparatus. When a cart is
used, use caution when moving
the cart/apparatus combination
to avoid injury from tip-over.

SECTION 2:
SET-UP & USE
1. DETERMINE SET-UP LOCATION
The Access Link is generally located near the amplifier. This minimizes the length
of cable runs, reducing cost and labor and minimizing the possibility of unwanted
EMI noise in the system. If cable runs longer than 12 feet are required, we
recommend using the balanced audio output with balanced audio cable.
NOTE: Do not install the Access Link inside a fully enclosed metal cabinet or box.
This will shield the box, cutting off all wireless transmission to and from the unit.

1. Plug one end of the included 3.5mm
cable into the AUDIO OUTPUT
connection on the Access Link.
2. Plug the other end into a microphone
or audio input connection on an
amplifier.
NOTE: depending on the type of
input jack on the amplifier, an adapter
or other audio cable with matching
plug may be required (not included).
3. Set the MIC/LINE level switch in the
appropriate position. Generally LINE
level is used unless the amplifier
input is specifically marked as a
“Microphone Input.”
In the event the Access Link must be
located more than 12 feet away from
the amplifier, it is recommended to
use the balanced audio output on the
Access Link. To ensure a fully balanced
connection, there must be a true
balanced input on the amplifier and a
balanced audio cable must be used.
1. Connect the stripped wires into the
marked openings on the euro-block
connector:
A. Insert the positive and negative
signal wires to the marked
terminals.
B. Insert the shield to the ground
terminal.
4. Secure the inserted wires by
tightening the retaining screws.
5. Connect the other end of the cabling
to a balanced input on the existing
amplifier.

If you are connecting into a new or existing Lightspeed Cat 855 or Cat 885
amplifier, you can use use Cat 5 cabling to integrate the two components (a
2’ cable is included with the system). This connection will send the audio from
Access Link to the Cat 855/885 as well as provide power for the Access Link (no
need for an additional AC power connection).
1. Plug one end of the Cat 5 cable into the AUDIO OUT/DC IN jack on the
Access Link.
2. Plug the other end into the “SENSOR INPUT” jack on the 855/885 amplifier.
3. Plug in the Cat 855/885 into AC power (if it’s not already) and the blue power
light on the front of the Access Link will light.
4. Access Link audio levels can be controlled with the Microphone Volume
control on Access Link as well as the CH A control on the 855/885 amplifier.

Audio Input
The Access Link has one AUDIO INPUT with volume control for connecting
to classroom audio sources. Use a patch cable (not included) to connect a
computer, iPod, iPad, or other audio source.
3. AUDIO INTEGRATION
Various classroom multimedia audio sources would typically be connected
directly into the audio amplifier to then be played through the classroom
speakers. However, there is an additional 3.5mm audio input directly on the
Access Link. That audio is passed through the Access Link and back out to the
amplifier.

4. CHARGING THE FLEXMIKE
Before use, the Flexmike should be charged. It will take 8-9 hours for the
Flexmike to obtain a full charge. A fully charged Flexmike will last for up to 8
hours of use. If microphones are used daily, they should be charged each night
– microphones can be left charging constantly for up to 2 weeks without causing
degradation to battery life.
When plugged into a charger, a red light on the Flexmike indicates the battery
pack is charging. A green light indicates that charging is complete and a full
charge has been reached. See Troubleshooting section for more information.
Replacement NiMH battery packs may only be purchased through Lightspeed
Technologies (part # NH2.4V). Do not attempt to charge with other battery packs.
They can overheat and expand creating a significant hazard and damaging the
microphone (this is not covered by warranty).
6. Hang the Flexmike on the lanyard
opposite the magnetic clasp.

1. Plug wall charger into an
electrical outlet.
2. Plug the USB charging cable(s)
into the wall charger.
3. Plug the micro USB end of the
charging cable into USB port on
the bottom of the Flexmike.
4. The charging light on top of hte
Flexmike will turn red to indicate
charging is in progress.
5. When the Flexmike is fully
charged, the light on the mic will
change to green.

5. OPERATING THE FLEXMIKE
Once the Flexmike is charged, follow these steps to set it up for use.
1. Remove the Flexmike from the
charging cable and put it on by
connecting the magnetic clasps
behind your neck. The Flexmike
will automatically power on and
mute when it is removed from the
charger. This will automatically
power on the Access Link as well.
2. The microphone volume on the
Flexmike is set at the factory to the
mid point.
3. While speaking in a normal voice,
fine-tune the microphone volume
on front of the Access Link up or
down. Proper volume level should
be as follows:
• Your voice should be clearly
heard by another person on the
other side of the room.
• You should barely be able to
hear your own voice.
• There should not be any audio
“feedback” or squealing
outside of 2-3 feet (if there is,
turn the volume down slightly).
REMEMBER: This equipment
supplements the user’s voice so they
are able to speak in a conversational
tone. Having the volume set too high
will result in feedback and listener
fatigue.
4. Once initial volume level is set,
walk around the room and listen
for overall audio quality.
5. If further fine-tuning is required,
you may need to adjust the Tone
Control on the front of the Access
Link or adjust the EQ on your
amplifier.

6. USING FLEXMIKE AS WIRELESS
AUDIO LINK
The Flexmike includes a 3.5mm audio input jack to
connect to an audio source like a laptop or MP3 player.
The Flexmike will transmit the audio signal to be played
through the system.
If your system includes two Flexmikes, you can use one
mic for instruction and the second mic to transmit audio
through the system.
1. Plug your external audio
equipment (for example, laptop),
into the input on the Flexmike
labeled “INPUT” using a 3.5mm
patch cable (not included).
