This four-stage charge sequence presents an optimum-charging plan that helps maximize the
overall life of the battery by managing two critical elements in the battery charging process, the
charge rate and overcharging protection. Note that NiMh batteries do not exhibit memory
problems and it is not necessary to drain the batteries prior to recharging.
Low battery status is indicated on the handset by the visual charge status on the display and/or the
audible warning tone.
The T7406 handset can be placed back into the charge cradle for charging when it is not in use.
• A fully depleted 1400 mAh battery will be restored to full charge in three hours.

1400 mAh battery in 12 to 14 hours.
