1. Getting ready/ Things you may need First of all make sure you have the items/tools need to complete the job. Along with the right tools you may need the items shown below. Please note that changes or modifications not expressly approved by RangeMaster for compliance could void the user's authority to operate the equipment. This unit is meant to be installed by someone who has some radio/technial background, a technician.

2. Starting the Installation Talk over the project with the customer. Find out when you will have access to the building. Before you start be sure you have a complete understanding with the customer: Where the transmitter will go Where the transmitter could go if the first choice will not work Where the studio is to go Other places the studio could go.
Generally the deeper your rod, the lower the resistivity will be. Bury any horizontal wires, the more ground/dirt contact the better. Just an inch or two below the surface will do. You can use a flat blade shovel to create a “trench” that the wire can be laid into. This works well with lawns. It is best to bury your rods entirely if possible to avoid anyone tripping over them, the lawn mower hitting them, ect. Some will bury any metal that will not corrode (tin cans, ect) in the area to help.
Do you see how the transmitter is mounted right next to the house? It is not above all buildings, the antenna is not in the open air, also look at the antenna, it is right up against the siding!! NO!! Even if this does work a little, range will be very low in the direction of the house. This transmitter needs to be moved up so that the antenna is entirely above the top roof line, preferably at or near the peak of the roof. NO!!!NO!!! CAUTION ! 2.

Working with the Inovonics 222 audio processor This type of equipment should have a balanced in/out connection, you will not need the audio AM1000pr adapter. Connections for balanced audio in. These connections should be the same for other audio processors. From the audio source, if the connector is an XLR connector you would use pins 2&3. Pin 1 is ground, don’t use that.
Unbalanced audio is a signal with a ground reference, usually a center wire with a outer ground, like a RCA jack, or coax cable. The center is the signal (hot) while the outer is the (ground) reference and shield. Here is the 222 wire diagram showing the input in the unbalanced method. This could be a 1/8 jack plugged into a computer sound card for example. When using the control cable Ferrite if the hole is to big try to loop the cable through twice.
Wire diagram for the transmitter system. There are two terminal blocks, either can be used. Not shown is the cable shield drain connection, connect it to the GND terminal on the terminal block in the transmitter. Be careful not to connect the power or audio to the (S+) or (S-) terminals, these are used for another function (RS485 sync).
5. Tuning and setting Power Coil Tune Block TUNE Audio Gain 12 Test Hole (3) crystal Be sure power is ON (LED should be lit) Turn Audio Gain all the way down (counter clockwise) Be sure to turn it back up when you are done. There are 3 test hole pads on the unit (see diagram). Take a standard voltmeter that is set to DC 5-20 volts and plug it into the bottom and top test hole pads. The black lead will go to the test hole pad closest to the mounting hole (Ground) (Top).

6. Trying to get good Range See the website for more information.
The transmitter should sound as loud as others on the dial, if it doesn’t there is a problem. It may be an audio impedance mismatch, or the level may need to be turned up. If the audio level isn’t high enough you won’t get good range, audio is a gate on the power, keep your audio turned up as high as you can. We have found the most common cause of low range is the audio setup, even more common then grounding problems. Not enough audio power (volume) and/or an impedance mismatch.
7. Better radio reception One of the toughest places to get radio reception is inside an office building. Construction materials like bricks and metal, and noise from computers and other electronics can all combine to make radio reception almost impossible for you. Besides the construction of the building, you sometimes have to account for your location in a building as well. I used to work at a corner desk in a windowless room on the 14th floor of a Manhattan office building.

A typical encounter with the FCC would entail just a phone call from them asking for your certification number. Most of the time (as long as you are using a certified transmitter) they won’t even come by to inspect your installation. You don’t want to be using an uncertified transmitter (especially a kit) if you get a call from the FCC. It is a good idea to broadcast your contact information at least hourly so that in case the FCC wants to contact you they can easily.

12. Using tuning computer When transmitter is turned on, the computer will start in Power Set mode if there is a shunt in J13 (Power is set last). When you are tuning you will get better readings with the power all the way down (Power Adjust counter clockwise). Also it will help if the Cap Tune (10 turn device) is about in the middle of it’s range (5 turns in from either way). Please note the tuning function is an alternative to using a meter.
To go to the Cap Tune program just leave the shunt in J13 for 15 seconds, the LED will turn off. Take the shunt off j13 (and then replace shunt onto J13) and you are in the Cap Tune program. To find the peak voltage using this program you need to get used to working with the program. As the voltage is steady or going up the LED will remain green, it will however tell you when the voltage is going down, and how fast. Turning the Cap Tune more quickly will give more red blinks as the voltage goes down.
Please note that changes or modifications not expressly approved by RangeMaster for compliance could void the user's authority to operate the equipment. This unit is meant to be installed by someone who has some radio/technical background, a technician. If you don’t feel qualified to install this unit yourself contact a local radio/TV shop. They may be able to help. Also if you have a friend who is a Ham radio operator they may be able to help you.
