PORTABLE WIRELESS SOUND SYSTEM OPERATING INSTRUCTIONS and trouble-shooting guide LECTROSONICS, INC.
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.
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 micro phone. Optional microphones, extension speakers and add-on equipment for a second wireless channel are avail able. These items will be discussed elsewhere in this manual.
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.
Portable Wireless Sound System 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.
SYSTEM SETUP RULES This section includes some basic rules that will ensure trouble-free operation of your LONG RANGER III system: 1) Make sure the transmitter battery is good, or better yet, new. 2) Charge up the battery pack in the LONG RANGER III fully before you use the system. Charge until the green charging lamp underneath the CH-40 jack on the LONG RANGER III control panel goes out. 3) Set up the system so that the LONG RANGER III is as far from large metal surfaces as possible.
Portable Wireless Sound System 7) Position the microphone on your person in the location it will be during actual operation. If you are using the headset microphone, turn the white knob on the headset fully clockwise (maximum). The microphone should be within 3 inches of the mouth to minimize the possibility of “feedback.” If the headset mic is being used, position the mic element at the corner of the mouth and rotate the white volume control knob fully clockwise.
USING ADDITIONAL SPEAKERS CAUTION! ALWAYS TURN THE LONG RANGER III POWER OFF BEFORE PLUGGING IN OR UNPLUGGING EXTERNAL SPEAKERS In some cases, the proper coverage of an audience requires a second speaker. The optional H300 is identical to the LONG RANGER III speaker and can be used to spread the sound over a larger area. Another optional speaker is the ES300, a column speaker designed for high quality voice or music reproduction at lower sound levels than the H300 mentioned above.

Using the supplied bright screws and lockwashers, connect the shield ring lug (the black wire) to the speaker mounting block.
INITIAL ADJUSTMENTS TO THE ADD-ON RECEIVER SYSTEM 1) Set up the Long Ranger III system according to the Initial Equipment Adjustments on page 6. 2) Leave the Long Ranger III power turned on. Set both volume controls on the Long Ranger III control panel to minimum. 3) Turn the Add-On receiver power switch to “ON.” Check to see that the power lamp comes on. 4) Plug the microphone into the transmitter that is on the same frequency as the Add-On receiver. The plug on the microphone is a twist-lock connector.
Portable Wireless Sound System MULTIPLE LONG RANGER III SYSTEMS A unique use of the AUX IN/OUT jack is for connecting two (or more) LONG RANGER III systems together for simulta neous use. When the LONG RANGER IIIs are interconnected in this manner, they will operate like a single system. You will have two (or more) wireless microphone inputs, two hard-wired mic inputs and much more audience coverage. The sound from all the LONG RANGER IIIs will be the same.
MICROPHONE CHOICES M119 - This is a very small, omni-directional mic used only as a lavalier (“lapel”) microphone. It may be prone to feedback since it is usually placed so far away from the users mouth; however it has a very flat response and excel lent tone quality. The M119 generally works best with the LONG RANGER III and an ES300 column speaker indoors at a lower volume setting. As is true of most omni-directional type microphones, the M119 is very free from wind noise and clothing “rattle”.
