This Bulletin Number is PSB F-471 APC - 720, 376 Date: November-1995 Deadline: November-1996 Memo To:PSB Mailing List (Direct/Indirect) From: Motorola Customer Resources Subject: Low Battery Audio Indicator Caused from Dirty Battery Contacts Kits Affected: All Visar Batteries Introduction: Recently, Motorola engineering teams conducting an analysis on Visarª field returns uncovered a failure condition that can give the appearance of low battery capacity as the failure condition. The analysis found that, in some cases, the low battery audio indicator is caused by contamination found on the battery contacts. This buildup of contamination on the battery contacts can cause the radio's low battery audio indicator to "chirp chirp" when the battery charge is not yet exhausted. Portables experiencing low battery audio alert may exhibit battery contact contamination rather than having a battery with low battery capacity. If contaminates are suspected or noted, it is recommended that the battery contacts be cleaned as follows. Corrective Action : Customers/Operators can clean and
protect their Visar Batteries with a cleaning kit - NTN8361A.
