– If the Batt LED is red, replace the batteries (see “Replacing the batteries”
on page 105). If you suspect that the batteries are fine, and the batteries
are fully charged, it’s possible the charger has detected a fault condition.
See “Resolving problems” on page 108 for details.
Charging the batteries
The SmartClass Tester uses an AC adapter or four (4) AA batteries (alkaline
or rechargeable NiMH batteries). The first time you use the SmartClass Tester,
or after prolonged storage, use the AC adapter to power the unit and charge
NiMH batteries only. For details on charging and maintaining batteries, see
Chapter 8 “Maintaining the Batteries”.
Exploring the front panel
The controls and LEDs on the SmartClass front panel, shown in Figure 1, are
used to operate the unit, set up tests, and view data.
The label near the top will say “SmartClass E1/Data”, if you have the
E1/Datacomm configuration.
The following paragraphs describe each of the controls and LEDs on the front
panel.
