2.6 Setting the Clock
To keep the clock in the Reader accurate, it will update automatically via the GPS
satellite network whenever a GPS signal is available. The precise clock is useful
for synchronizing tag reads in multiple Reader installations. In this situation, ensure
that all of the Readers have been synchronized with the GPS time when setting up
a multi-reader system.
NOTE: So that your local time appears correctly on the display and in log files,
please set the current time zone in the settings menu (refer to Section 3).
To set the clock, move outside or place the unit near a window with a clear view of
the sky. The time taken to update the clock will depend on the quality of the GPS
signal, varying from a few seconds to a few minutes. You will notice the time and
date change to the correct values. If the clock has not updated after 5 minutes, try
positioning the reader in an area with a better view of the sky.
If the reader clock has become invalid, a message will appear upon turning on the
reader: “The Clock Could Not Synchronize – GPS Signal Is Required.”
This can happen if the Reader has been in storage for a long time and the internal
battery has become deeply discharged. Fully recharge the battery as soon as
possible before using the unit to read tags. Follow the above procedure to set the
clock.
2.7 Using the GPS Receiver
The HPR Plus Reader is able to store location information (latitude and longitude)
along with each tag read, this is known as “geotaging.” Geotagging can be turned
on or off in the settings menu, please refer to Section 3. When using this feature,
be sure that the unit has a valid GPS lock; otherwise the geotag information will not
be stored along with the tag read.
The GPS icon on the main screen will change from red to blue when a valid GPS
lock is obtained and the Reader is now tracking its location.
To obtain a GPS lock, position the Reader in an area with a clear view of the sky.
Achieving a valid GPS lock usually takes less than 2 minutes, but can take up to 5
minutes or more, particularly if the Reader has not been operated in the area
before or has been switched off for a long time.
