Below is a review of the important features of the Maxima receiver. Integrated Antenna: A key feature of the Tracker Maxima receiver is the integrated fold- ing antenna. Tracker antennas feature steel hinges connecting the antenna elements to the receiver. You will notice that the antennas are made of virtually unbreakable circuit board material. -
Page 7: Operating The Receiver
Operating the receiver: To utilize the receiver, first unfold the antennas before activating the receiver. The receiving antennas are located to the front of the receiver and when fully extended are perpendicular to the axis of the receiver. The reflecting antennas are located to the back and when fully extended form a 75 degree angle to the axis of the receiver. -

Page 10: Selecting Memory Locations
Selecting Memory location: Use the L and M buttons to move between Memory locations that have programmed frequencies saved. The programmed frequencies are displayed at the bottom of the Display. During programming, use the L button to change to a higher number and the M button change to a lower number. -

A unique feature of the Maxima receiver is the automatic gain control mode. The “smart electronics” contained in the receiver will automatically set the gain control based on the strength of the signal. Note that automatic is good to help find a signal; Manual is best for precise direction finding. -

Use only the 9 volt DC regulated adaptor available from Tracker. Automatic Shut-off: The Tracker receiver features an automatic shut-off circuit that will guard against running down the batteries if the receiver is inad- vertently left on. Most receivers are set to shut down after 15 minutes if no button is pressed. -

External antennas are commonly employed when tracking from a vehicle or aircraft. Moreover, a multi-element directional antenna can provide greater range when tracking a very weak transmitter. Most Tracker transmitters are powerful enough to not require an external antenna except in specilized circumstances. PROGRAMMING Adding a frequency: 1. -

to select correct number. Note that pressing the ENTER key moves the editor 1 digit to the RIGHT and pressing the MODE key moves the editor 1 digit to the LEFT. 3. Repeat until frequency at bottom of display matches desired frequency. -

Page 16: Changing The Batteries
Changing the Batteries: Retaining screw 1. Start by turning the receiver upside down to allow access to battery compartment. 2. Loosen the retaining screw on the battery cover and remove the cover exposing the two 9 Volt batteries. 3. Replace BOTH batteries with 9 Volt batteries of same type and equal strength. -
Page 17: Using Your System
Do not store receiver in a wet holster. If unit is sub- merged in water or becomes soaked, immediately remove the batteries and ship unit to Tracker where it can be chemi- cally cleaned and dried. WARNING: If a receiver is stored wet and left to dry, pockets of water may be left under com- ponents. - Page 18 The unique antenna of the Tracker Maxima is designed to favor reception from one direction. When the Maxima is pointing in the direction of the transmitter, the signal will be stronger.
- Page 19 To become proficient with the operation of the receiver, you should consider activating a transmitter, and have someone in your family or group place it in an open area free from obstructions (where it can be relocated, if necessary). A good distance to start would be at least several hundred yards.
- Page 20 (open fields, forested area, etc.). By this point, you should have mastered the few controls that are required on the Tracker receiver. This is important as your attention should be focused on analyzing the signal rather than operating the receiv- er.
- Page 21 on interpreting the signal. As you proceed with more complicat- ed searches, it is important to keep moving as you are process- ing new data at each new location rather than re-sampling the same data when stationary. Follow a similar procedure as in the previous example. Have someone from your family or unit hide the transmitter in an area that will provide a range of obstructions (physical and/or man- made) and special situations (inside a building, adjacent to metal...

• Implement a "process of elimination" strategy. If the signal is difficult to "read" remove from consideration all line-of-sight locations that you do not receive a strong signal. You will notice that the signal in the open field led you directly to the transmitter while in hilly area the direction changes slightly as you move around obstacles and hills. -

scale is logarithmic not linear. This means the change in gain from 1 to 2 is very small as compared to the change in gain from 5 to 6, i.e. gain at 1 to 2 is for 50 to 100 ft. while gain at 5 to 6 is for ⁄... -

example, if the transmitting antenna is perpendicular to the ground, the signal strength detected by the receiver will be great- est when the antennas are positioned vertically. You can test this for yourself by activating a transmitter and orienting the antenna on the transmitter parallel to the ground. -
Page 25: Location Of Receiver
Location of receiver Similar to the location of the transmitter, any given signal can be received at greater distance if the receiving antenna is high in the air, therefore, a stronger signal may be obtained by positioning the receiver higher off the ground. NOTE: It is much worse for the receiver to be in a low terrain than the transmitter. - Page 26 Figure 3: Plotting triangulation bearings on a topo map. The circle defines the most likely location of transmitter degrees). Note that, other things being equal, the arc may be greater the closer you are to the transmitter. Listen for small changes in the signal strength (headphones can be very help- ful to detect the bearing of maximum signal strength).

3. If the arc of received signal is, say 30 degrees, note the bear- ing of the “break” in signal (where the signal drops off) on each side and choose the mid-point of the arc as the most likely bearing to the transmitter. 4. -

TRANSMITTERS: For many applications, Tracker markets transmitters with the Maxima receivers, as a package. See the manual for your trans- mitter type or download off of www.trackerradio.com TROUBLESHOOTING: Receiver will not turn on 1. Make sure you are pressing and holding the ON/OFF button for at least 2 seconds. - Page 30 2. If audio distorts when backlight comes on, send unit in for repair. 3. If audio is distorted all the time, send unit in for repair. Antenna/s loose or too tight 1. DO NOT try to tighten or adjust the front antennas, this can damage the circuit board and will void your warranty.
- Page 31 3. If available, compare receiver with another receiver with same transmitter. If range is considerably less, send unit in for service. Display screen flashes on and off 1. This is a programmed response; the number of flashes indi- cates the type of problem the receiver self check system has discovered.
