7. Installation
7.1 Easy Trim Function (ETF)
This function allows adjustment of the reader to its environmental conditions.
The ETF is a semiautomatic function for trimming the reader to its best performance.
The ETF starts after switch S1 has been pressed (see 3.1 “Rear View”, switches).

The ETF starts after switch S1 has been pressed (see 3.1 “Rear View”, switches).
In this mode only one of the three LEDs is blinking. The individual meaning of each LED is
as follows:
as follows:
Red LED:
The rotatable switch (S2) must be turned to the right.
Yellow LED: The rotatable switch (S2) must be turned to the left.
Green LED: The setting of the rotatable switch (S2) matched the best performance.
Green LED: The setting of the rotatable switch (S2) matched the best performance.
In some cases there might be two settings of the switch indicating the best performance. If
there are two possible positions for the rotatable switch (S2), we recommend to select the
position before the yellow LED has been blinking.

The ETF ends after switch S1 has been pressed again. It will also end automatically after 6
minutes.

If the reader should be mounted directly on metal surfaces (distance to metal less than 2
cm), switch S3 has to be actuated before the rotatable switch S2 is being turned.

7.2 Possible Interference Sources
Warning:
It is possible that external interference sources may influence the reading
range, e.g. monitors, switching power supplies, power cables parallel to
data cables, mounting on metal surfaces etc.
It is possible that external interference sources may influence the reading
range, e.g. monitors, switching power supplies, power cables parallel to
data cables, mounting on metal surfaces etc.
LCD monitors have a minimal influence on the reading range. In particular the reader should
only be mounted on non-metallic material, such as plastic or wood. Metal screws (M6 – ISO
1207, 4762 or 7045) for mounting of the reader have an insignificant influence on the
reading range.
The unit needs to be operated with a power source with limited power
consumption according to EN 60950-1(2001) paragraph 2.5.

Note:
With growing distance between reader and interference source the
influence will decrease.

Use only linearly regulated power supplies which are offered by deister electronic GmbH.
In order to reduce the influence of external electrical interference the cable shield has to be
connected to ground (GND) of the power supply.
