  • Time management for cordless telephone by inputs from a user through the keypad to cause data to be transferred to the external source via input terminals and mating terminals on a battery charger
    Patent number: 5528667
    Abstract: A cordless telephone which includes a static RAM (50) for storing time management information and a real time clock (52). The time management information which includes telephone numbers and diary information is written into the static RAM (50) using a personal computer (PC) during recharging of the telephone's batteries. In operation, the telephone's microcontroller (40) compares the real time with entries stored in the static RAM (50) and when there is coincidence, an alert is given to the user. Alternatively data entered into the static RAM (50) by a user using a key pad (46) or derived from a received radio telephone link can be read-out to the PC when the batteries are being recharged.
