This Bulletin Number is PSB F-469 APC - 402 and 720 Date: September-1995 Deadline: September 1996 Memo To:PSB Mailing List (Direct/Indirect) From:Motorila 2-Way Dealer Product Services & Direct Product Services, Plantation Fla. Subject: Scan Optimization HT1000/VISAR Conventional Radios Radios Affected: Conventional model VISAR and HT1000 radios manufactured between February and July 1995. Serial Numbers: 720AVCxxxx - 720AVNxxxxx and 402AVCxxxx - 402AVNxxxx Model numbers: H01KDH9PA3AN , H01RDH9PA3AN, H01SDH9PA3AN Cause: An Audio Signal Filter Integrated Circuit (ASFIC) implemented in February (P/N 5105835U27, U41) may require an optimization of a scan timing parameter called initial sample delay. A three millisecond increase in the parameter will insure that squelch break in scan/battery saver more closely approximates standard channel squelch break levels. Corrective Action: After the install of the RSS patch file for HT1000/VISAR/JT1000 version CP.v31, into programming station the following steps can be taken: 1. When in the HT1000 directory, type "CPFIXV31" Note 1: The codeplug value which is optimized using the above tool can also be 'cloned' from one radio to the next. After a like model radio has been processed through the above steps, it can be used as the source radio in radio-to-radio cloning; allowing for in-field optimization if the same radio personality and feature set is to be used. Note 2: The application of this Codeplug optimization to radios with the original ASFIC will not result in any damaged or any significant change in the performance of those radios. Note 3: Since this parameter is "clonable", care should be taken that a template previously created with the earlier scan timing defaults be deleted or updated to insure that the new codeplug value is maintained going forward. To receive a copy of the RSS patch file, fill out the form on the back and return it by fax to Customer Resources. The diskette will be shipped within two business days to the address listed. $15 labor is authorized by warranty for the above symptom.
