The assert error data isstored in flash memory until you power cycle the handset. You can use theConfiguration Cradle to retrieve this information as an .asrt file, which youcan then send to Nortel technical support for further debugging.Use the steps in Procedure 31 "Recording an assert error message" (page218) to record and retrieve assert error data.ATTENTIONDo not replace the battery pack before you perform the steps in Procedure 31"Recording an assert error message" (page 218).Procedure 31Recording an assert error messageStep Action1 Write down the error message that appears on the LCD display.Nortel Communication Server 1000WLAN IP Telephony Installation and CommissioningNN43001-504 01.02 StandardRelease 5.0 15 June 2007Copyright © 2004-2007, Nortel Networks.
