5.5.4Battery Connections Test

Use this test to check the battery connections in the unit.

The battery connections test time is approximately 5 minutes:

1.Remove the battery cover and battery from the unit.

2.Inspect the battery for physical damage. If damage is evident, replace the battery.

3.Insert and remove the battery several times to check the battery connections and back plate of the unit.

If either components are damaged, replace the unit.

4.Check the battery contacts for foreign material. Use a gold contact cleaning pen (see Appendix A: Ordering Replacement Parts & Kits for part number) to clean the contact area on the battery.

FCAUTION: Do not use a pencil eraser or similar material to clean the contacts. If you do, damage can occur to the contacts.

5.Check the battery cover to ensure it fits and attaches properly to the back of the unit. Replace, if necessary.

6.Use a pencil or similar object to depress the battery contacts. They should spring back to their original position.

If the battery contacts do not spring back, they are damaged. Replace the unit.
