Long Ranger 4
LECTROSONICS, INC.6
This section covers the initial adjustments to the
transmitter and Long Ranger that must be made before
the system is placed into operation. The step-by-step
procedures are listed in the order in which they should
be performed:
1) Turn Long Ranger power on - The POWER lamp
lights.
2) Rotate both volume controls counter-clockwise to
their minimum settings.
3) Position yourself behind the Long Ranger so that
the sound from the speaker will be directed away
from the microphone.
4) Plug your microphone into the transmitter. Make
sure the connector is screwed in snugly.
5) Turn the transmitter power on and verify that the red
lamp on it lights. If the lamp is very dim or does not
light, replace the battery.
6) Observe that the green RF lamp on the Long
Ranger control panel is lighted. This verifies that
the unit is receiving a usable signal from the
transmitter.
Initial Equipment Adjustments
This section includes some basic rules that will ensure
trouble-free operation of your Long Ranger system:
1) Make sure the transmitter battery is good or new.
2) Charge up the battery pack in the Long Ranger fully
before you use the system. Charge until the green
charging lamp underneath the CHARGER jack on
the Long Ranger control panel goes out.
3) Set up the system so that the Long Ranger is as far
from large metal surfaces as possible. Metal
surfaces under the unit (such as pickup truck cabs
or a car top) are generally no problem but large
metal surfaces alongside the Long Ranger may
interfere with wireless reception.
4) If you have more than one transmitter on the same
frequency, turn on only one transmitter at a time.
You cannot use two transmitters at the same time
with a single Long Ranger. You will need to “alter-
nate” back and forth between the transmitters.
Failure to do so will result in an obnoxious whining
sound from the system, and the audio will probably
not be understandable. “Add-on” wireless mic
systems are available separately to permit opera-
tion of two transmitters simultaneously through a
single Long Ranger.
System Setup
5) Use the minimum volume that will enable everyone
to hear. It doesn’t have to be loud to be heard.
6) Always turn the power off before connecting or
disconnecting external speakers.
7) The Long Ranger should be elevated for best
coverage. The unit should ideally be at least 2 feet
higher than the audience. For example, with an
audience standing on flat ground, the number of
people that can hear clearly will double if you raise
the unit from 5 feet above the ground to 7 feet
above the ground.
8) During actual operation the Long Ranger should be
located at least 20 feet away from the person using
the microphone and aimed so that the sound from
the speaker is directed toward the audience and
away from the microphone. This will reduce feed-
back problems. Feedback is a squealing sound
coming from the speaker when the volume is too
high or the microphone is too close to the Long
Ranger. Feedback is generally much more of a
problem when using lavalier (lapel) type micro-
phones. The headset models are recommended
for use with the Long Ranger system since they
place the microphone pickup much closer to
your mouth, which increases the volume of the
Long Ranger before feedback occurs.
7) Position the microphone on yourself (or other user)
in the location it will be during actual operation.
If you are using the single-band or dual-band
headset microphone, turn the white knob on the
headset fully clockwise (maximum). The HM162
over-ear microphone should be positioned so that
the pickup element is just to the left of the mouth,
so that breath pops do not strike the capsule.
Lavalier microphones should be positioned high on
the chest or collar, as close to the mouth as pos-
sible to minimize the possibility of feedback. A
handheld microphone with the H175DC plug-on
transmitter should be kept at a consistent distance
from the mouth during setup and use.
8) A small screwdriver is supplied with belt-back
transmitters to adjust the audio gain of the transmit-
ter to match your microphone and your voice. The
plug-on transmitter has a small knob for adjusting
gain. The adjustment is made while observing the
MOD LEVEL lamps on the Long Ranger control
panel:
