case, there is always a metal screen behind the display. You may have to try
several different positions on a laptop before you find one that does not impair
the range. We recommend that you should always temporarily fit the tag on
assets containing metal and check the range is adequate before fixing it down
permanently. Once you have found the best position on, for example, a
particular model of laptop, you will then be able to fit the tag in the same
position for all similar models. Remember to ensure that the tamper switch
spring is pushed in when doing these tests. The tamper alarm always operates
at high power at long range. Never re-use the adhesive pads on tags.
If you have to re-locate a tag replace the adhesive pad and always de-grease
the mounting surface using methylated spirits or other de-greasing agent.
(3) The range set using the RAT is designed to compensate for the reduction in
range that occurs when asset tags are mounted on metal or when personnel
tags are worn close to the body e.g. in a pocket. You will find that tags held
clear of metal or bodies will operate at a greater range than that set by the
RAT.
(4) The level of ambient background noise will affect range consistency;
whilst noise filtering is employed in the reader design it cannot filter certain
types and levels of noise which are within the scope of the data rate. Please
refer to the Important Installation Notes in Section 2.2 ‘Siting the Reader’.
(5) If after setting the range, the red power LED continues to flash slowly, then
the range setting is invalid. Repeat the range setting process.
