1. An electronic device powered by a battery, comprising:
- a receiver for receiving a message;
a vibrator capable of vibrating at a selected one of at least two frequencies for alerting a user of the received message;
selector means for enabling a user selectable frequency of vibration of said vibrator which optimizes the user'"'"'s response to the vibrator; and
controller for monitoring a characteristic of said vibrator and for adjusting a parameter of said vibrator in response to the monitored characteristic for maintaining a constant rate of vibration of the selected frequency of vibration of said vibrator.

Abstract
A selective call receiver (100) comprises a receiver (104) for receiving a message and a vibrator (116) capable of vibrating at a selected one of at least two selectable frequencies for alerting a user of a received message. The vibrator (116) also has a selector (120) or a tuning element (130) for varying the frequency of the vibrator (116).

13. A selective call receiver powered by a battery, comprising:
-
a receiver for receiving messages; a vibrator capable of vibrating on at least two frequencies of vibration for alerting a user of the selective call receiver of the reception of a message on one of the at least two frequencies of vibration; selector means for enabling a user selectable frequency of vibration of said vibrator which optimizes the user'"'"'s response to the vibrator; and controller means for monitoring a characteristic of said vibrator and for adjusting a parameter of said vibrator in response to the monitored characteristic of said vibrator for maintaining a constant rate of vibration on the selected frequency of vibration, said controller means further controls said selector means in response to the monitored characteristic for determining when to select the other frequency of vibration, said selector means capable of automatically selecting the other frequency in response to said controller means. - View Dependent Claims (14)

15. In an electronic device for providing a tactile alert of a received message to a user of the electronic device, a method comprising the step of:
-
(a) selecting a frequency of vibration of a tactile alerting device capable of vibrating on at least two frequencies whereby the selected frequency optimizes a user'"'"'s response to said tactile alerting device; (b) monitoring a characteristic of the tactile alerting device; (c) adjusting the frequency selected in response to step (b) for maintaining a constant frequency of vibration; and (d) automatically selecting another frequency of vibration in response to step (c) when the adjusting step cannot maintain the constant frequency of vibration. - View Dependent Claims (16, 17, 18, 19)

20. An electronic device powered by a battery, comprising:
-
a receiver for receiving a message; a vibrator capable of vibrating at a selected one of at least two frequencies for alerting a user of the received message; selector means for enabling a user selectable frequency of vibration of said vibrator which optimizes the user'"'"'s response to the vibrator; and controller for monitoring a characteristic of said vibrator and for adjusting a parameter of said vibrator in response to the monitored characteristic for maintaining a constant rate of vibration of the selected frequency of vibration of said vibrator, said controller further controls the selector means in response to the monitored characteristic of said vibrator for determining when to select another frequency of vibration, said selector means capable of automatically selecting another frequency in response to said controller.
