2.3 MEASURING READ DISTANCE
Make sure you know the tag types. For certain readers and tags, user must also be
mindful of the tag s orientation and the reader s antenna orientation, what mounting
surface the tags are designed for and how the tags are supposed to be mounted. Any
departure from its intended purpose will drastically affect the reader s ability to energize
the tag and its read range.

When measuring the reader s read range, make sure that the tag is properly oriented to
the reader antenna, and for optimum performance, be sure the operator s finger is not
within three (3) inches of the tag s antenna surface.

3 INSTALLATION & OPERATION GUIDELINES
3.1 SITE SURVEY
Always conduct a site survey before starting installation. Avoid any possible sources of
interference. For best result, use a spectrum analyzer with a wideband antenna and set
the spectrum analyzer in Max Hold mode to gain measurement of the maximum signal
strength on the airwave. If the MPR-2010BR reader is not installed properly, the
performance will be degraded. Listed below are steps that should be followed during
installation:

performance will be degraded. Listed below are steps that should be followed during
installation:
· Do not install reader in an area where sources of broadband noise may exist.
Avoid mounting the reader facing a cellular phone tower or in close proximity to the
base station of a 900 MHz wireless telephone.

· Keep all of the reader wiring a safe distance from all other wiring, including, but
not limited to, AC power, computer data wiring, and telephone wiring, and wiring to
electrical locking devices.

· Avoid operating the reader in close proximity to other 900 MHz wireless local
area networking (WLAN) equipment. It should be noted that MPR-2010BR readers
are known to work in electromagnetic crowded areas, such as trade shows.

3.2 PREFERRED READER INSTALLATION PRACTICES
· Avoid mounting the under direct sunlight. Exposure to direct sunlight may cause
the reader to operate at a temperature above the 65 degrees Celsius upper limit.
