Since the unit may appear to be functioning normally, it is
important to verify proper battery orientation as follows:
Press ON.
Select STATUS. Wait 5 seconds.
Read BATT voltage.
NOTE: Fresh batteries should produce a reading greater
than 6.0 volts.
A reading of less than 3.5 volts may indicate a reversed battery
and orientation should be double-checked.
6.3.1.6
Setting Battery Time
The Vibrex unit has a feature that tells how much time the user
has been operating a set of batteries.
NOTE: If the user already has time use on the batteries,
the battery voltage indication is the best guide to battery
health, since resetting the battery time results in a zero
reading for battery time in service.
To ensure the accuracy of this reading, set the battery time after
new battery installation, as follows:
1. Select the BATT context key.
2. Press RESET FOR NEW BATTERIES.
CAUTION: After the user replaces an EPROM chip, the
battery time automatically resets to zero.
6.3.2 EPROM Replacement
The EPROM chip in the Vibrex 2000 or Vibrex 2000 Plus
defines the features contained in the unit and has a version
number that corresponds to these features.
