1. A 950-mAhr lithium-ion battery pack provides power for the PTC-921 DOS.

2. These contacts on the PTC’s battery pack connect with similar contacts on the SC-921 DOS. The electronic impulses for all communication

between the PTC and the cradle and the power for recharging the PTC’s battery pack pass through these contacts. See Appendix D for the
pinouts of these contacts.
