11. Only use attachments/
accessories specified by the
manufacturer.
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.
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

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 re or electric shock, do not
expose this apparatus to rain or
moisture.

2A. SETTING UP ONE DELTA PA RECEIVER
1. Turn the DELTA PA ON by rotating
the POWER/RCVR 1 knob
clockwise. The green LED will
light.
Channel Selection: Receiver
Each Receiver has 16 user-selectable
channels to choose from. You can
either select a channel manually or
by pressing the SCAN button, which
will automatically select a clear
channel.
2. Clear Channel SCAN
(recommended):
A) Make sure the transmitter(s) is
OFF before pressing this button.
When this button is pressed, the
receiver will cycle through all
16 channels and select a clear
frequency. (This process takes
about 20 seconds.)
B) Once the receiver selects the
clear channel, you will need to
select the same channel on the
corresponding transmitter
(handheld or belt-pack). See
pages 14 and 19 for instructions.
NOTE There are 3 different
groupings of 16 channels available
(620, 640, 660 MHz). Make sure the
receiver module frequency group
is the same frequency group as the
transmitter.

channel on the corresponding
transmitter (handheld or belt-
pack). See pages 14 and 19 for
instructions.
4. Set the Receiver 1 and Receiver 2
channels on the second DELTA PA
to be the same as the rst DELTA
PA.

TERYTYPE ON HANDHELD MICROPHONE
Battery Low Indicator
Battery low indicator is located
above the power switch. It glows red
when the battery charge is low and
recharging is necessary
Battery Type
The transmitter will operate with
either standard AA alkaline batteries
or nickel metal hydride (NiMH)
rechargeable batteries. Since these
types of batteries have different
characteristics, it is important not to
mix battery types. Use only AA NiMH
batteries when recharging.
NOTE: Do not mix battery types.
WARNING: Do not use NiCad
batteries! They will not charge
properly and may cause damage to
the transmitter.
Lightspeed recommends Panasonic
or Energizer batteries. Duracell may
not work.

stacked end to end.
3. Note the polarity in the battery
compartment.

6. RECHARGING BATTERIES IN HANDHELD
MICROPHONE
Recharging the Batteries
(NiMH Rechargeable Batteries
ONLY):
Make sure there are NiMH
rechargeable batteries in the
transmitter before plugging in
the charger. A full charge will be
attained in 8-10 hours. Fully charged
Lightspeed microphones will last
over 7 hours.
WARNING: Do not attempt to
charge alkaline batteries. They can
overheat and expand, creating a
signicant hazard and damaging the
transmitter. (This is not covered by
warranty.)
1. Switch the transmitter power OFF.
2. Insert the small DC plug into the
jack on the bottom of
the transmitter.
3. Plug the other end of the charger
into any standard 110 VAC outlet.
4. The red LED on the charger will
light, indicating that charging is in
progress.
5. When the batteries are fully
charged, the LED on the charger
will glow green.

7. CONNECTING AND PLACING BELT-PACK
TRANSMITTER
Connecting the Microphone
To connect the microphone, simply
insert the microphone connector
into the TA4F connector on top of
the transmitter. To remove, press
the black button on the microphone
connector and pull out.
Microphone Options
Lightspeed offers two types of
microphones that can be used with
this system. The BP016 Transmitter
can be used with either a lapel
style microphone or a headset
microphone. Both plug into the top
of the transmitter as shown.
Lapel Microphone Placement
Simply connect the microphone cord
directly into the jack on top of the
transmitter and clip the microphone
to lapel or collar. For optimal sound,
position the microphone as close to
the mouth as possible.
Headset Microphone Placement
Simply connect the microphone
cord directly into the jack on top
of the transmitter and place the
headset around the back of the
head. For optimal sound, position
the microphone at the corner of the
mouth.

9. GAIN ADJUST ON BELT-PACK
TRANSMITTER
NOTE: If you are using a high impedance
source, such as a guitar, it will be necessary to
adjust the GT dial. Using a high impedance
source requires a special cable. Contact
Lightspeed Customer Service at 800-732-
8999 for more information. Customers in
Canada should contact their local reseller.
Gain Adjust:
When changing microphones or
users, it may be necessary to adjust
the transmitter gain based on
differing microphones sensitivities
and voice levels.
To adjust the gain:
1. Open the battery compartment
door by depressing the latches on
each side of the transmitter.
2. Turn the MT dial clockwise
to increase the gain and
counterclockwise to decrease the
gain.
