Never lose track of your portable valuables! Great for traveling! Attach the signal transmitter to your briefcase, notebook computer, or any other valuable items. Carry the receiver with you on your key chain. FEATURES: A precise, mini electronic guarding system. Perfect for safeguarding your valuable items, including Cellular Phones, Notebooks, briefcases, hand bags....etc. Rechargeable function eliminates replacement headaches and saves money. PRODUCT INCLUDES: 1pc Transmitter (TX) (Attached to your valuable) 1pc Receiver (RX) (Attached to your person) 1pc Rechargeable Base 1pc AC Adaptor OPERATING INSTRUCTIONS: 1. Turn on the Receiver (RX) unit. The red LED light will illuminate and you will hear a long beep followed by continuous short beeps. Now, the RX is ready to cooperate with Transmitter (TX) unit by learning its code. 2. Turn on the TX unit. You will hear a fast beep signal consisting of one long and one short beep. After this, the beeping sounds will stop. This indicates that the TX has successfully connected with the RX. Both red LED lights will blink simultaneously. On the other hand, if you still hear continuous beeps, you should turn both the TX & the RX off and on again to link their codes together. 3. Once the connection between the two units has been activated, you should attach the RX to your person (ie: on you key chain in your pocket) and the TX to your valuable possession (Cell phone, Notebook computer, wallet, etc.). Separating the two units by more than 6-15 feet (about 2-5 meters) will trigger 3 short beeps to sound continuously in order to remind you that you are away from your valuable. Range may vary from place to place. 4. Recharge both the RX & the TX if RX beep sounds become weak, or if their responding distance becomes shorter. 5. Always turn both units off when recharging their batteries. 6. The Rechargeable Base red LED light will illuminate during the recharging process. When the red LED light turns to green, this indicates that the RX or the TX is fully charged. Note: To follow its IC process, always turn on the RX first and the TX second. When you accidentally turn off either the RX or the TX during operation, you must turn off both units and start from the first steps of the operation as instructed above. Please keep the RX & the TX separated by at least 2/3 feet (20cm) during learning code status. This is the minimum distance required. The batteries' duration after each recharge will be around two weeks depending upon usage. Always turn both the TX & the RX to the off position when not in use. Always disconnect the AC adapter after recharging. Do not use this device when on board an airplane. Do not use this device in the rain. WARNING: Do not use any other AC Adapter with this FOLLOW ME. Furthermore do not use this Ac Adapter with any other products. FCC ID : OLA - DX-147 This device complies with Part 15 of the FCC Rules.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. NOTE This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection. This equipment generates, uses and can radiated radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. 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 encouraged to try to correct the interference by one or more of the following measures: Reorient or relocate the receiving antenna. Increase the separation between the equipment and receiver. Connect the equipment into an outlet on a circuit different from that to which the receiver is connected. Consult the dealer or an experienced radio/TV technician for help. The antenna(s) used for this transmitter must not be co-located or operating in conjunction with any other antenna or transmitter. Changes or modifications not expressly approved by the party responsible for compliance could void the user's authority to operate the equipment. Follow Me

Operational Description 1. The circuit function and device operates 1.1 The transmission unit being made up of 4 sections: the charge able battery +3.6v, the micro co ntroller digita l encoder, 433. 92 MHz SAW resonator and RF transmission ci rcuit (Refer to attached tr ansmission block drawing) . The code being modulated to 433.92 MHz freque ncy point, using ASK modulation type (detai ls please refer to the code description ), the frequency band width is 1 MHz. The Duty cycl e of code is 1:3. The bit rate is 1100bps. 1.2 The receiver unit being made up of 5 sections: the chargeable battery +3.6v, +3v power regula tor, RF receiver demodulation, micro controller digital decode r and alarm circuit (Refer to at tached receiver block drawing). The 433.92 MHz high frequency signal being mixed with the LOF, and output 1.8 MHz IF signal, then input to micro controller to decode, and drive the speaker by output. 1.3 When Using, power on the receiver unit at first, the LED of receive r unit will glow long time, a nd the receiver unit will s end out long sound “BE” at first, then short sound “BE”(i nterval time is 1.6s or so), then power on the transmission unit, the receiver unit will send out long sound “ BE”, which means that the study code of receiver and transmission unit is successful, at the same time the LED of receiver and transmission unit will twinkle. The r eceiver unit will not send out sound until the distance between the receiver and trans mission unit is out of the specification. When the streng th of alarm sound is too small or the rece ive distance is too short, which means to the transmission and receiver units need to charge. Put them to the charger, LED sends out red light, afte r about 2.5 hours, LED se nds out yellow light, which means to the charge is full enough.(Still have small current to go on charging, but which will not damage t he chargeable battery and charger.) 2. Attached statement 2.1 The transmission unit being put to the travel bag or box, receiver unit being ke pt with you, put it to your pocket or hang up at your waist. 2.2 The same frequency band and metal object will make the receiver distance shorten. 2.3 When charging, power off the r eceiver and transmission units. 2.4 To make the transmission and receiv er unit operate normally, pl ease keep the distance of them farer than 20cm. 3. The code description 3.1 Define: a. The start code: Occupy 1 bit code widt h. Being made up of the high level(0.56ms) and the low level(2ms). The wave type as be low: b. The data code: Occupy 16 bits code widt h. “1” means that high level is 0.56ms and low level is 0.28ms. “0” means that high l evel is 0.28ms and low level is 0.56ms. The wave type as below: c.
