SECTION 4:
TROUBLESHOOTING
COMMON PROBLEMS AND SOLUTIONS
Note:
No sound when someone speaks
into the wireless microphone:
1. DELTA PA power should be on.
The green LED should be lit. If it
does not light when the system
is switched on, make sure the AC
power supply is plugged in.
2. Microphone/transmitter power
should be on. If the low battery
indicator is on (red) the batteries
are most likely too weak. If the
batteries are rechargeable, plug
the microphone/transmitter into
the charger. If the batteries are
alkaline, replace them with new
alkaline batteries
WARNING: Do not attempt to
charge alkaline batteries. They can
overheat and expand, creating a
significant hazard and damaging
the warranty. (This is not covered by
warranty.).
3. The transmitter and receiver
should be set to the same
channel. The blue RF LED (A or B)
should be lit.
4. Verify that receiver and transmitter
are in the same frequency group.
Turn the DELTA PA off and then
on again. The letter code from
the frequency group will blink
on the receiver module. Open
the battery compartment on
the transmitter and be sure that
frequency group printed on the
sticker matches the frequency
group letter code that blinked
when the DELTA PA powered on.
If the letters are different, find a
microphone or belt-pack with
the same frequency group as
the receiver indicates when the
DELTA PA is turned on.
If you review these instructions and still have questions, write down the
serial number and model number of your system and call Lightspeed
Technical Services at 800.732.8999, 5 a.m. – 5 p.m., PST. Customers in
Canada should call their local reseller.

The wireless mic is experiencing
drop-out or interference:
1. The wireless frequency being
used may not be a clear channel.
Turn the transmitter off and press
the SCAN button on the receiver
to find a clear frequency. Then
select the same channel on the
transmitter.
2. Transmitter is out of range of
receiver. The transmitters have a
maximum range of about 300-350
feet in an open field environment.
This range can be dramatically
reduced indoors and outdoors
when large objects (such as a
wall) may be obstructing the path
directly between transmitter and
receiver. If so, position the two
closer together.
3. Batteries are very weak. Right
before the batteries are about
to die, the overall performance
of the system can be drastically
lessened. Check the battery status
of the transmitter.
Low Volume or Feedback:
1. Ensure microphone is positioned
appropriately.
2. Check volume level on the
amplifier. If the volume is too
high, feedback will occur. Adjust
accordingly.
