Abstract
A holster for a radio pager contains an electrical element which can be detected by the matching radio pager when the pager is inserted into the holster. In one embodiment the pager and holster have matching electrical contacts which are made when the pager is inserted into the holster. The pager contains means to sense the connection of a specific impedance and to convey this data to an internal control device. The control device has the capability to alter the mode of alert from vibrate to an alternate alert mode such as audible alert, according to the pre-selected choice of the user, under control of the low impedance sense signal. The holster sense circuit output is also used by the control device to invert the orientation of displayed information, to provide for on-belt reading of a front faced display pager.
