3 USE: The deactivator is determinate for the deactivation the RF sticker labels in frequency range 8.2 MHz ± 3.625 %. The deactivator can also detect deactivation less hard tags in the above-mentioned frequency range. The deactivator works with all kinds of hard tags and sticker labels in the market for 8.2 MHz The synchronization between deactivators and EAS system is the way for the elimination of bad influence between the deactivators and EAS system. This bad influence usually comes out as EAS system sensitivity decreasing or false alarms. 2. BASIC DEVICE DESCRIPTION 1. Embedded 4 LEDs indicate the following deactivator state: - The deactivator unit is powered - Internal synchronization - LF synchronization led to the deactivator unit - The detection of sticker label or tag 2. Maximum deactivation height is up to 40 cm. NOTE: Maximum output power of the deactivator, 40x40 mm sticker labels. * 3. Maximum detection height is up to 40 cm. 4. Sound indicator of the detection hard tag or sticker label with possibility of volume adjustment. 5. The deactivator unit works in only one mode. Detection with deactivation. 1. BASIC INFORMATION
4 3. DEACTIVATOR PARAMETERS AND THEIR MUTUAL INTERACTIONS 3.1 SENSING AND DEACTIVATING POWER The deactivator needs two output power levels for its operation. RX Sensitivity Level - Is used for the detection of sticker labels and tags. The bigger this power is the higher detection height is reached, but the higher the probability is, that the sticker label is deactivated before its detection. The level of sensing output power (RX) is found experimentally by reaching acceptable detection height and probability of successful detection by mod ifi c a ti on tr i mmer RX PWR tr i mmer . Th e va lu e of this parameter is set at 50 %. NOTE: All Power settings MUST be left at default settings in USA. USA versions do * n o t a l l o w f o r p o w e r a d j u s t m e n t s Deactivation output power - Is used for deactivation of sticker labels. This level is set at manufacture. Bad influence usually comes out as EAS system sensitivity decreasing or false alarms making. It is necessary to perform proper synchronization between EAS system and the deactivator.

5 3.2 DEACTIVATOR OPERATING MODES The deactivator unit can o n l y work in 1 mode. MODE1 - deactivation with detection - The deactivator emits ‘deactivation output power’ pulses, which are defined by TX PWR trimmer. The response after deactivation pulse is analyzed in order to look for the presence of sticker label or tag inside detection area (above or under deactivation pad). 4. CONFIGURATION OF DEACTIVATOR'S PARAMETERS 4.1 THE USAGE OF ONE OR TWO DEACTIVATOR PADS If it is intended the usage of the only one deactivation antenna (deactivation pad) it makes no difference, if it is connected to the terminal ANT1 or ANT2. We recommend keeping recommended dimensions of the deactivation antenna; it fits 90 % of installations. The usage of two deactivation antennas/pads can be requested in some cases. It can happen mainly in three following cases: 1. It is requested to have two deactivation antennas/pads, which are not distant more than approximately 2-3 m (for example one can be normal deactivation pad and the second one can be embedded into bar code reader). 2. One deactivation antenna/pad is required, but bigger deactivation field is requested than one deactivation pad can give. Both of deactivation antennas should be connected to terminals ANT1 and ANT2 (for example first deactivation antenna can be connected to the terminal ANT1 and second one to the terminal ANT2). Both of antennas will work the same way as per settings of the operational mode (MODE1, MODE2, MODE3 or MODE4). Pic. 2 - Recommended dimension of deactivation antennas and their connection to the deactivator
6 4.2 SETTINGS OF THE DEACTIVATION POWER The deactivator deactivation power is determined by settings of the TX PWR trimmer. The value of this parameter determines the height of the deactivation field. This level should be chosen the way to assure the reliable sticker labels deactivation. There is general rule valid, that 50 % level of output power is sufficient for the most sticker labels. Th e va l u e of this parameter is set at 50 %; setting beyond this level is not allowed by the manufacturer. This setting cannot be changed in USA models. 4.3 SETTINGS OF DEACTIVATION RX SENSITIVITY The deactivator features having the adjustable level of sensing power RX PWR (the power, what is needed for the detection of the sticker label without its deactivation). The correct setting of this parameter is very important for the sticker label detection. Too small sensing output power will give small detection height, but on the other hand, too big output power can deactivate the sticker label without its detection. The correct level of this parameter varies on the sticker label brand. The value is set 50%. This setting cannot be changed in USA models 4.4 SETTINGS OF THE STEPPING FREQUENCY RANGE The deactivator is factory set to detect the standard sticker labels. Stepping frequency range will assure the detection of sticker labels, which are out of the standard operational frequency range of the RF EAS system. Bigger sweeping frequency range will mean less detection height on the other hand and vice versa. Th e va lu e of this parameter issetat50 % fixed; setting beyond this level is not allowed by the manufacturer and is fixed for USA models.

INSTALLATION There are several simple and essential rules mentioned, which keeping will assure very good parameters of the deactivation. • Don’t install deactivation antennas/pads to the near proximity of metal objects. There should be no metal object under the deactivation antenna/pad closer than from 3 to 4 cm. There should be no metal object next to the deactivation antenna/pad closer than from 5 to 10 cm. • Don’t install the deactivation antennas/pads to the close proximity of the other electronic devices. • Don’t install wire between the deactivator unit and the deactivation pad/antenna along with the others cables. • Pay your utmost attention to install deactivators as far as possible from the RF EAS system. The particular minimum distance depends mainly on the quality of used RF EAS system. 5.1 FAULTS CLEARING
