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.

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

Figure 23: Charge Spare Battery

Ensure that the Battery indicator lights blue. If it does not, make sure that
the AC adapter is plugged in and that the spare battery is making good
contact with the Charger Unit.

Charge the spare battery for 15 to 20 hours.
