Q79-703Child Perimerter Safety Device

GOTCHA™ Child Perimeter Safety Device by National Scientific Corporation Thank you for purchasing the NSC Gotcha™ Perimeter Safety Device. These units can be thought of as an ‘electronic leash’ with a variable range. When the child wanders beyond the range that has been set for them the child unit will automatically alarm. When the child comes back into your comfort zone the alarm can either be canceled from the parent unit or it will automatically cancel. This product is intended to assist you in keeping track of your children in busy environments, such as shopping malls or parks. One parent unit can track multiple child units simultaneously (additional child units sold separately). Owner's Manual Version 1d © 2003 National Scientific Corporation Please read this operation manual carefully before using the product. Please keep this manual in a safe place for future reference. A full version of this manual is also on our web site www.national-scientific.com BASIC PRODUCT USE Gotcha consists of two units: one part is worn by the parent (parent unit) and the other is worn by the child (child unit). The child unit also has an anti tamper feature. If the child unit is removed the alarm will automatically activate. The alarm can only be canceled by re-attaching the unit to the childs clothing and pressing the LOCATE/CANCEL button on the parent unit. Each parent unit has a unique ID code. Each child unis must be programmed to recognise the correct parent unit it belongs to. This means that your child unit will now only respond to your parent unit. However additional child units may be bought and programmed to operate with a specific parent unit. The parent unit has a LOCATE/CANCEL button and an on/off switch. The child unit is automatically switched on by opening the belt clip and attaching it to the childs clothing. It can only be switched off by a comand from the parent unit. When your child wanders beyond the preset perimeter, the child’s unit will automatically sound an alarm. This audible child unit alarm (there is no alert directly in the parent unit) alerts you that the child is outside the safety zone. You should immediately respond to this alarm. You can easily locate your child by following the direction of the alarm sound. The alarm will either automatically re-set or it can be cancelled by the parent pressing the LOCATE/CANCEL button on the parent unit when your child is back inside the safety zone. For added safety, the child unit is also designed to alarm when tampered with. Warning THIS PRODUCT DOES NOT TAKE THE PLACE OF STRICT AND ATTENTIVE ADULT SUPERVISION. IT IS INTENDED AS A TOOL TO ASSIST ADULTS IN KEEPING TRACK OF NEARBY CHILDREN. BUTTONS BATTERY INSTALLATION Your Gotcha parent unit requires one CR2 battery and the child unit requires one 2032 battery BATTERY INSTALLATION AND SET UP Parent unit: 1. Turn parent unit off (switch in the up position). 2. Locate and remove the 2 battery compartment screws (located at the top back corners of the unit) with a small Philips screwdriver. 3. Remove battery compartment cover. 4. Remove old battery (if installed) noting polarity. 5. Install new battery ensuring correct polarity with diagram in battery compartment. 6. Re-attach battery door and fasten screws. Child unit: 1. Remove battery compartment screw (located at the top right hand corner of the back face). 2. Remove battery compartment cover. 3. Insert CR2032 battery (by sliding it under the battery clip) into to child unit with the +ve symbol facing up. 4. Re-assemble the battery compartment and screw. BUTTONS (PARENT) FUNCTION OFF TO ON (PARENT) SWITCHES THE PARENT UNIT ON ON TO OFF (PARENT) SWITCHES THE PARENT UNIT OFF, ALSO SENDS CODE TO CHILD UNIT THAT IT WILL BE SWITCHED OFF. RANGE (PARENT) SETS THE DISTANCE THE CHILD CAN WANDER. 3 SETTINGS OF CLOSE, MEDIUM AND FAR LOCATE / CANCEL (PARENT) IF THE CHILD UNIT IS NOT IN ALARM – THE CHILD UNIT WILL BE LOCATED IF THE CHILD UNIT IS IN ALARM – THIS WILL CANCEL THE ALARM CLASP ON CHILD UNIT ON / OFF FUNCTION AS WELL AS TAMPER TEACHING ADULT / CHILD UNITS: The child unit now must be taught to listen out for the correct parent unit. Each parent unit has a unique ID code. Each child unist must be taught which parent unit it belongs to. This means that your child unit will now only respond to your parent unit. 1. Open the clip on the back of the child unit. 2. Attach the child unit to either a piece of clothing or some other thin object (such as this card) that will keep the clip open. 3. The LED on the child unit will now flash rapidly. 4. Place the parent unit near the child unit. 5. Switch on the parent unit. 6. The LED on the parent unit will flash rapidly and then pulse regularly 7. Press the locate / cancel button on the parent unit until the alarm stops – the child unit should chirp the locate alarm Note: In the unlikely event that the child unit does not recognize the parent unit it will emit a series of long beeps after about 20 second these beeps should stop. The LED on the Child unit should now pulse approximately every 2 seconds. 1. Remove the child unit from the item it was attached to and close the clasp. 2. The child unit should now alarm (anti-tamper feature). 3. Re-attach the child unit to the item it was attached to. 4. Press the locate / cancel button until alarm cancels – the unit will now stop alarming To become familiar with its operation and features, you should now experiment with your Gotcha!! TO SWITCH THE UNITS OFF 1. Switch parent unit off. 2. LED on parent unit will stop flashing. 3. Child unit will begin to chirp (warning that it is expecting to be switched off). 4. Remove child unit from clothing. 5. Close clasp on child unit. 6. Chirping will stop and unit is switched off. NOTE IF YOU TAKE LONGER THAN 5 SECONDS TO REMOVE THE CHILD UNIT THE CHILD UNIT WILL AUTOMATICALLY ALARM. YOU WILL HAVE TO SWITCH THE PARENT UNIT BACK ON AGAIN AND REPEAT STEPS 1 THROUGH 6. RANGE SENSITIVITY The range sensitivity switc…
