2.6 MAINTENANCE
If the T-BERD 107A fails to operate and no
front panel indicators are illuminated:
•
Check the T-BERD 107A AC power adapter
to ensure that it is securely connected to the
T-BERD 107A.
•
Make sure that the power supply is uninter-
rupted by plugging another electrical de-
vice into the electrical outlet used by the
T-BERD 107A.
•
If AC power is not connected to the
T-BERD 107A, connect the T-BERD 107A
AC power adapter to the ADAPTER con-
nector and a compatible AC power supply
and charge the battery for a minimum of 15
minutes.
If the T-BERD 107A fails to operate after the
T-BERD 107A AC power adapter and power supply
are found to be in proper working order, contact the
TTC Customer Service Department at (800) 638-
2049. If front-panel indicators are illuminated, but
the instrument does not operate properly:
•
Use the Instrument Self-Test/Checkout
procedure in Section 2.5 to localize the
problem.
