Data Sheet

a). Search, detection, and alarm range depend on the terrain environment.
b). If the beep sound is not loud enough, the batteries may be low. Change with new batteries for louder alarm sound.
c). If you want to use the device during flight trips, please comply with the flight safety law according to each country.
d). The signal will be disconnected if the Base unit and Tag units are within 10 cm from each other (the signal c
onnection will be overloaded). When the Base unit can’t connect to Tag unit, the Base unit alarms every second and
Tag unit’s LED light flashes.
d). We reserve the right in changing the specification of the hardware and software designs to manuals at any time and
without prior notice. Information in this document is subject to change without notice.

FCC CERTIFICATIONS
Federal Communication Commission Interference Statement
This equipment has been tested and improved to comply with the limits of a Class B digital device, pursuant to Part 15
of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a
residential installation. This FCC Certifications equipment generates, uses and can radiate radio frequency energy, if
installed and used not 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 determinedly turning the equipment off and on, the
user is encouraged to try to correct the interference by one 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.
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 an interference received, including interference that may cause undesired operation.
FCC Caution: Any changes or modifications are not expressly approved by the party responsible for compliance which
could void the user's authority to operate this equipment.
CARE AND MAINTENANCE
FREQUENT ASKED QUESTIONS
Q. During searching mode: Why does the Base unit show more than one directions?
A. In search mode, the system collects and compares the signal strength to determine direction.
Sometimes signals from different directions have similar signal strength and may cause the Base unit o show
more than one direction. This normally happens when the Tag unit is already very close to the Base unit and
both units are in an enclosed environment, which causes signal reflection. If the signal strength LED tells
you that you are already very close to the Tag unit the easiest way to fix this problem is to mute the Base unit
and track the beeping sound from the Tag unit to locate missing items.
Q. Why did I get wrong direction? When I followed the direction indicator from base unit
A. This is also caused by the reflection of the signal. Sometimes, the signal from the correct direction has been
eakened by signal blocker(s), but the signal from a wrong direction has been amplified by combining several
wrong reflection signals ( from multi sources; like metal wire fences..). To solve this wrong direction issue,
you have to follow the direction indicatorand move forward a few more steps. Once both status LED lights
turn off for over 1 second, you know you are moving toward a wrong direction. You can restart your search
for correct direction again then.
Q. What can cause false range alarm?
A. False alarms are caused by following reasons:
1. Both Base and Tag unit are too close to each other.
2. Low battery power will cause unpredictable behaviors.
3. Unit has been placed in a pocket with a lot of other material.
Q. Why is range alarm distance not consistent?
A. Because radio signal strength and signal refection are affected by the environment. Users may need
to adjust range to compensate for environment factors.
