questions
Here you will find the most frequently
asked questions and answers about your
UPS. For further help, visit www.philips.

To keep the warranty valid, never try
to repair the system yourself. If you
encounter problems when you use your
UPS, check the following points before
you contact Philips. If the problem remains
unsolved, go to the Philips website www.
philips.com/support or contact Philips at
919-575-7863 in North America. When
you contact Philips, make sure that your
UPS is nearby and the model number and
serial number are available.
What should I do if I cannot turn the UPS
on or the LED light will not illuminate?
This may occur if the battery voltage
is less than 10V. Recharge the UPS for
a minimum of six hours. If the problem
persists, it may be PCB (Printed Circuit
Board) failure. You will have to call for
service to replace the PCB.
What should I do if my UPS is always
operating in the battery back-up mode?
First, make sure the power cord is
securely engaged in the AC outlet. If the
power cord is secure, it may be possible
the AC fuse is burnt out. Check the fuse
and replace, if necessary. If the AC fuse is
operational and the problem persists, the
line voltage may be too high, too low or
blacked out. In this case, you must wait for
a return to normal conditions. If none of
these solutions return the UPS to normal
operation, it may be PCB failure. You will
have to call for service to replace the PCB.
What should I do if the UPS back-up time
is too short?
This could occur if the UPS battery is
not fully charged. Recharge the UPS bat-
tery for a minimum of six hours. If, after
recharging the battery, the UPS back-up
time is still too short, it may be due to
