FINDING YOUR WAY
MAINTENANCE AND DIAGNOSTICS
The endpoints and chargers have been designed to withstand the wear and tear of nor-
mal use. However, you should avoid dropping the endpoint or knocking it against
hard surfaces. Carrying the endpoint in a holster or carrying case will help to protect
it.
There are no serviceable parts in the endpoints or the chargers. You should not open
the endpoint case nor disassemble the chargers. Doing so will void your warranty.
If you experience problems with your endpoint, a diagnostics tool can help you deter-
mine if your endpoint is operating properly.
To use the diagnostic tool:
1. With the power off, hold down the and buttons. The serial num-
ber of the endpoint and the port information will show on the display.
2. Release the button, then release the button. After a few seconds,
the endpoint will vibrate (Model 8525 and 8526 only) and flash solid squares
and Zs across the top two lines of the display.
3. Release the buttons. The display will then flash all the items at the bottom of the
display. The display should look similar to the one shown on the page 4.
4. To turn the diagnostics off, hold the button until you hear one beep.
If anything is missing from the display, there is something wrong with the endpoint
and it should be returned to Inter-Tel for repair or replacement.
