Operation is subject to the following two conditions: (1) this device may not cause harmful interference, and (2 ) this device must accept any interference received, including interference that may cause undesired operation. Caution: Any changes or modifica tions not expressly approved by Tattle-Trail LLC could void the us er's authority to operate the equipment. This equipment has been tested a nd found to comply with the limits for a Class B digital device, pursuan t to part 15 of the FCC Rules. These limits are designed to provi de reasonable protection against harmful interference in a resident ial installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio comm unications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is en couraged to try to correct the interference by one or more of the following measures: 1. Reorient or relocate the rece iving antenna. 2. Increase the separation be tween the equipment and receiver. 3. Connect the equipment i nto an outlet on a circuit different from that to which the receiver is connected. 4. Consult the dealer or an experienced radio/TV technician for help. Medical: Consult the manufacture of any personal medical devices, such as pacemakers or hearing aids, to determine if they are ad equately shielded from external RF (radio freque ncy) energy, (The product -4- operates in the frequency range of 2.405 GHz to 2.480 GHz, and the power output is 200mW (max.).) -5- Tattle-Trail Monitoring System* Introduction The Tattle-Trail monitoring syst em is designed to sense the amount of vibration on vehicles towed behind a truck, RV or toterhome. When m onitored parameters on the towed unit exceed what the ope rator sets as normal, both audible and visual alarms ar e generated. Once notified, the operator can take action to prevent further property damage. Depending on the sensitivity setti ng selected and the type of towed unit, Tattle-Trail may be able to detect abnormal vibration levels. Some failures that may cause increased vibration are: tire tread separation, flat tire, loose lug nuts, broken suspension components, malfunction of hitch assembly and runaway of the towed unit. Additionally, if the “Sensitivity” knob is placed in the “Park” mode and the Tattle-Trail units are w ithin communication range, theft detection may be sensed. The portable TTK 550 Tattle-Tra il system is not designed to be exposed to the elements. Always ensure that this unit is installed inside both vehicles and not exposed to the weather. If a water resistant transmitter enclosure is required, Tattle-Trail LLC offers a weather hardened enclosure (Model TTK 700) designed for permanent mounting to a towed unit. Check www.Tattle-Trail.com for more details. -6- * Tattle-Trail is a trademark of Tattle-Trail LLC Installation: Transmitter Tattle-Trail Model TTK 550 is a “plug and play” system that is highly portable and requires no user calibration. To use, simply follow these instructions: Remove the unit marked “Transmitter” from the carrying case and locate a mounting area high and in the center of the towed unit’s windshield (up near the mirror but not obstructing driver’s vision ). With the power cord facing down and forward, moisten the suction cups and firmly press the unit to the windshield (see Figure 1). Then plug the male 12VDC power plug into the closest powered 12VDC receptacle. A flashi ng green “Link” light will illuminate indicating that the “Transmitter” has power and is self calibrating. The “Link” light will quickly turn solid green indicating that the unit has calibrated and is transmitting data. -7- Towed Vehicle Figure 1 Note: During the flashing green calibration mode, minimize any motion in the towed unit. Warning: Both Tattle-Trail units are internally fused, but it is important to protect the wiring going to the unit by utilizing a fused power source. Warning: Do not ever submerge either the transmitter or receiver in fluid. Once the transmitter has calibrate d, it tries to “Link” with the receiver. After 3 minutes, if the receiver is not turned “On”, the transmitter will go into “Sleep” mode to conserve power. Every 5 s econds, the transmitter wakes up to look for a signal from the receiver. If no “Link” is established, then the transm itter returns to “Sleep” mode. Receiver Remove the unit marked “Receiver” from the carrying case. Rotate the “Sensitivity” knob to the full counterclockwise (CCW) “OFF” position. Now, with the towing vehicle parked, plug in the male 12VDC power connector into a powered receptacle of the towing vehicle. With the towed un it’s “Transmitter” powered up and calibrated, turn on the “Receiver” and set the sensitivity knob at about 2 o-clock. Both the green “Link” light and the green “Alarm” light should be illuminated. Since dash configurations vary from v…
