Abstract

A pager has a display and a selectively activated light for illuminating the display. The illumination of the display is accomplished using a minimal number of components thereby reducing the size and cost requirements of the pager. The method of message sequencing and the illumination of the pager display is controlled solely by the pager user through a single switch.

Claims

1. A method for illuminating a display of a pager which has at least one switch which initiates both an operational function of the pager upon actuation of the switch and display illumination, the method comprising the steps of:

actuating said switch;

performing said operational function by said pager upon actuation of said switch, and

illuminating said display of said pager after said switch has been actuated continuously for a predetermined time period.

2. A method for illuminating a display of a pager as recited in claim 1 wherein said operational function comprises transferring a message from a memory to said display.

3. A method for illuminating a display of a pager as recited in claim 2 including a step of deactivating the illumination of said display after a second predetermined time period has elapsed following said transfer of said message from said memory to said display.

4. A method for illuminating a display of a pager as recited in claim 1 wherein said predetermined time period is adjustable.

5. A method for illuminating a display of a pager as recited in claim 4 wherein said predetermined time period is selected by setting switches mounted on said pager.

6. A method for illuminating a display of a pager as recited in claim 4 wherein said predetermined time period is selected by choosing an option presented by operation of a user program in said pager.

7. A method for illuminating a display of a pager which has at least one switch which initiates both an operational function of the pager and display illumination, the method comprising the steps of:

actuating said switch;

illuminating said display of said pager after said switch has been actuated continuously for a predetermined time period, and

performing said operational function by said pager in response to deactuation of said switch.

8. A method for illuminating a display of a pager as recited in claim 7 wherein said operational function comprises transferring a message from a memory to said display.

9. A method for illuminating a display of a pager as recited in claim 8 including a step of deactivating the illumination of said display after a second predetermined time period has elapsed following said transfer of said message from said memory to said display.

10. A method for illuminating a display of a pager as recited in claim 7 wherein said predetermined time period is adjustable.

11. A method for illuminating a display of a pager as recited in claim 10 wherein said predetermined time period is selected by setting switches mounted on said pager.

12. A method for illuminating a display of a pager as recited in claim 10 wherein said predetermined time period is selected by choosing an option presented by operation of a user program in said pager.

13. A method for illuminating a display of a pager which has at least one switch which initiates both an operational function of the pager and display illumination, the method comprising the steps of:

actuating said switch;

illuminating said display of said pager after said switch has been actuated continuously for a predetermined time period, and

initiating performance of said operational function by said pager after illuminating said display.

14. A method for illuminating a display of a pager as recited in claim 13 wherein said operational function comprises transferring a message from a memory to said display.

15. A method for illuminating a display of a pager as recited in claim 14 including a step of deactivating the illumination of said display after a second predetermined time period has elapsed following said transfer of said message from said memory to said display.

16. A method for illuminating a display of a pager as recited in claim 13 wherein said predetermined time period is adjustable.

17. A method for illuminating a display of a pager as recited in claim 16 wherein said predetermined time period is selected by setting switches mounted on said pager.

18. A method for illuminating a display of a pager as recited in claim 16 wherein said predetermined time period is selected by choosing an option presented by operation of a user program in said pager.

19. A method for deactivating the illumination of a display on a pager which has at least one switch which initiates both an operational function of the pager and reactivation of illumination of said display, the method comprising the steps of:

actuating said switch;

deactivating the illumination of said display of said pager after said switch has been actuated continuously for a predetermined time period, and

performing said operational function by said pager.
