Charge the Spare Battery

It is recommended that you have a spare battery always charging to protect against complete battery discharge. The charger unit is equipped to charge the spare battery with or without the handset in the front slot. See Appendix C, “Accessories” for information on ordering a spare battery.

1Slide the spare battery into the rear slot in the charger unit until the retaining clip snaps over the top of the battery.
