INTRODUCTION
Thank you for selecting the Long Ranger III Portable Wireless Sound System. This system represents over 80 years of combined experience in the design of RF transmitters, receivers and Public Address systems. The Long Ranger III sets new standards for operational convenience, flexibility and mechanical ruggedness. The built-in wireless receiver, the rechargeable power supply and the high audio output set this system apart from any other portable PA system on the market.
This manual covers the standard LONG RANGER III, optional microphones, trans­mitters, extension speakers and the “add-on” 170MINI-LR wireless microphone system.

Portable Wireless Sound System
GENERAL TECHNICAL DESCRIPTION
The standard LONG RANGER III Portable Wireless Sound System consists of a combination wireless receiver/ amplifier/speaker with a rechargeable battery pack, an M175 or M175LS belt-pack transmitter and a headset micro­phone. Optional microphones, extension speakers and add-on equipment for a second wireless channel are avail­able. These items will be discussed elsewhere in this manual.
The LONG RANGER III features a VHF wireless microphone system with a transmitter-to-receiver operating range of up to 750 feet. The receiver is designed for high selectivity to prevent interference from other transmitted radio signals. The system is designed and constructed for rigorous portable use with the antenna integrated into the horn speaker to eliminate damage.
The LONG RANGER III will operate from 8 to 12 hours from the “on-board” rechargeable battery pack before recharg-
ing is necessary. The actual operating time is dependent upon the type of usage....intermittent or continuous. The
unit can also be operated from an external 12 Volt DC source. An accessory power cord is available to allow opera­tion from a vehicle cigarette lighter receptacle.
The amplifier produces 33 Watts, RMS, into the 8 Ohm horn speaker. The sound output will cover an area the size of a football field under average outdoor conditions. Several LONG RANGER IIIs can be easily connected together to provide even greater area coverage.
RECHARGEABLE BATTERIES AND EXTERNAL POWER SOURCES
The battery pack in the LONG RANGER III is charged by plugging the CH-40 charger into the jack labeled CHARGER on the control panel of the LONG RANGER III. Connect the charger into a standard 110 Volt AC outlet. The green lamp beneath the jack will light as long as the batteries are charging. When the batteries are almost completely charged the green charging light will go out. You may leave the charger plugged in after the green light has gone out with no danger of damage to the system. In fact, we recommend charging the system whenever it is not in use, then the system will always be “ready to go”.
Since the LONG RANGER III consumes more power than the CH-40 charger can supply, the batteries will recharge faster if you turn the LONG RANGER III power off while charging. The batteries normally require 2 to 6 hours to recharge. If the unit is completely run down, it may require as much as 24 hours to fully charge the batteries. Leave the charger plugged in at least until the green lamp below the CH-40 jack goes out.
(NOTE: In the case of severely discharged batteries (this can happen if the Long Ranger has been left on constantly for several months), it may be necessary to charge the unit for a much longer time. Up to 10 days charge time is not uncommon in these circumstances.)
The LONG RANGER III can be operated from an external 12 Volt DC source such as an automobile battery or, most commonly, from the cigarette lighter receptacle in your vehicle. To use an external power source it must be connected into the 12V DC POWER INPUT jack on the LONG RANGER III front panel. CAUTION--Make sure you comply with the polarity markings on the jack. The correct plug for making the connections is a Radio Shack 274-1567A which can be obtained through electronic parts suppliers. Lectrosonics cord number 21329 is available through your dealer for connecting your unit to a vehicle cigarette lighter receptacle. When an external power source is connected to the LONG RANGER III, the on-board battery pack is automatically disconnected.

CONTROLS AND FUNCTIONS
CONTROL PANEL
WIRELESS MICROPHONE VOLUME
Turns unit power on and off and also functions as the volume control for the internal wireless receiver.
POWER
A red LED that lights when unit power is on.
RF
A green LED that lights when the companion transmitter is turned on and there is sufficient signal for good system operation. Internal circuits monitor both signal level and interference levels and decide if the transmitted signal is strong and “clean” enough for satisfactory operation. If not, the green RF LED will go out and the receiver will “squelch”, shutting off the sound output. This action is automatic and requires no user adjustment.
MOD LEVEL
The red and green MOD LEVEL LEDs continuously indicate the modulation level(audio level) of the received signal from the transmitter and are used when making initial adjustments to the transmitter.
MIC
This jack is a standard 1/4" phone jack and is used for plugging in the cord from a dynamic microphone such as the Lectrosonics M121S.
LINE
This mini jack is used for connecting high level, high impedance outputs from tape decks or other amplifiers. It also may be used for connecting the “earphone” output from portable cassette players.
AUXILIARY INPUT VOLUME
Adjusts the volume of the MIC and LINE inputs.
AUX IN/OUT
An RCA phono jack that functions both as a line level input and line level output. This “omnibus” jack is primarily used for interconnecting several LONG RANGER IIIs together for simultaneous operation. This jack can also be used with a tape deck to either record from or play back into the LONG RANGER III. When used with a tape deck or other audio source, the sound output level must be controlled by the volume control on the tape deck since there is no volume control on the LONG RANGER III for the AUX IN/OUT jack. When an external device is connected to this jack, the loudness of the Long Ranger III will usually be reduced.
CH-40
A special jack used for connecting the CH-40 charger when charging the battery pack. The green LED located under the jack lights when the batteries are charging. This LED automatically goes out when the batteries are almost fully charged.
12V DC OUTPUT
A special jack used to supply power to the Add-On receiver when that option is installed.

FRONT PANEL
12V DC EXT POWER
A special jack used to connect an external 12 Volt DC source to the unit to substitute for the “on-board” battery pack. It is most commonly used for connecting the LONG RANGER III to a vehicle cigarette lighter receptacle. When an external power source is connected to this jack, the on-board battery pack is automatically disconnected.
EXTERNAL 8 OHM SPEAKERS
Two jacks which are used to connect external 8 ohm horns or speakers such as the Lectrosonics H300 horn or ES300 column speaker.
