A heating device capable of evenly heating a thermal recording medium without increasing the cost of the device is disclosed. The method includes determining whether a sleep time exceeds a threshold, buffering time domain samples containing acquisition pilots and a paging channel, powering down RF circuitry in the access terminal after buffering samples, processing the samples to compensate for drift, and determining whether the access terminal was paged based upon the processed samples. A vertically adjustable veneer tie enwraps the J-hook, limiting lateral movement and front-to-back displacement, and is set within the bed joint of the outer wythe. That position where a substrate to be processed is present is set in a substantial non-magnetic field state, so charge-up damage is prevented.
