This Bulletin Number is PSB F-464 APC - 376, 720 Date: March - 1995 Memo To: PSB Mailing List From: Radio Products Group/Product Services, Plantation Subject: Cleaning Process Description for Visar Battery Contacts Symptom: Radio resets when bumped, intermittent radio
- battery contact Corrective Action: It is therefore recommended that the following process be performed on a regular basis. 1. With the battery removed from the radio and with the label and contacts facing you, inspect the contacts for mechanical degradation i.e. nicks, cuts, scratches in the contacts or plastic. Order replacement batteries if mechanically damaged. 2. If possible, hold the battery inverted so that contaminants fall away from the battery and do not lodge in recesses at the edge of contacts. 3. a) Using a clean pink eraser, stroke the contacts in the
same direction as the length of the contact. With a dry bristle
brush (toothbrush), brush away the eraser particles. b) Using a cotton swab in good condition, wet the tip in
isopropyl alcohol and wipe in the same 4. After cleaning, re-inspect contacts. Ensure that recesses at edge of contacts are free from cleaning materials. |
