Self Test
The Self Test should be the initial step in trouble- shooting problems with ROLMphone 300/600 series telephones. The purpose of the Self Test is to perform an internal check of the telephone. A successful Self Test causes all status lights to flicker briefly, and the display, if present, to light for one second.
Begin the Self Test
Unplug and replug the line cord from the telephone base and observe the status lights and display. (The process of unplugging and replugging the line cord from the telephone base is also referred to as “resetting the telephone.”)
Note
Make sure the handset is in its cradle before running the Self Test.
Evaluate the Self Test Results
See if the Self Test results match any of the problems listed below. If so, follow the recommendations. If not, see if your problem is listed in “Other Problems” on page
All the status lights flash, but the display does not light up.
The telephone has failed the Self Test. Call your CBX system administrator or the appropriate service personnel.
No status lights flash when the telephone is reset.
There is a problem with either the telephone base or the line cord. Verify that the line cord is connected securely at both ends.
