6.3 TRIMMERS DESCRIPTION
Pic. 5 - Location of trimmers on the board.
TX PWR - Deactivation output power (set at 50%).
RX PWR - Sensing output power (set at 50%).
Stepping - The range of sweeping is set from the production fixed at 50%.
SYNC - The time between the request for deactivation and transmission of
detection/deactivation pulse and the settings of deactivation output power TX PWR and
RX PWR) The purpose of trimmer is to put the detection/deactivation pulse into time,
where the EAS system doesn’t analyze the tag and sticker label response and therefore it
is resistant to deactivator transmissions (time multiplex principle). VOLUME - The volume of
buzzer – the indication of the hard tag or sticker label detection.
6.4 LEDS DESCRIPTION
PWR - Power supply LED.
LF - Signal on low frequency synchronization terminal LF SYNC IN.
EXT - Indication of the internal synchronization.
ALARM - Alarm LED.
PEDAL - Pedal switch LED.
FM - The indicator, if currently received and FM demodulated signal is good enough
for proper external synchronization.
