A portable, low maintenance apparatus is provided for cooling down athletes following strenuous exercise. The apparatus has a repository that holds ice, and a fan configured to blow air through the ice and out of a face adapter part. The face adapter is shaped to provide a cool, breathable stream of air to a user who presses his face up against the adapter.

A transmitter includes a modulator, a power amplifier and a controller to reduce the effects of phase cancellation in a simulcast paging system. The modulator is digitally configurable to modulate according to at least two protocols. The controller configures the modulator for a first protocol and provides to the modulator a signal to be broadcast. The modulator then modulates this signal according to the first protocol and causes the modulator to introduce a random frequency offset within a frequency range predetermined to optimally reduce phase cancellation for the first protocol. When the controller provides a signal to be broadcast according to a second protocol, the controller reconfigures the modulator for the second protocol. In addition the controller causes the modulator to introduce a random frequency offset within a predetermined range to optimally reduce phase cancellation for the second protocol. Because the controller can change the frequency offset on a protocol basis, phase cancellation errors can be optimally reduced for both protocols. In addition, the transmitter can easily be reconfigured to support new protocols as they are developed without changing the existing transmitter hardware. Still further, the randomly changing offsets dispense with the need to maintain records of the offsets for each transmitter in the simulcast paging system.
