A mobile terminal receiving a transmitted cycle comprising first and second data parts operates in a power-saving mode in which a relatively high power-consuming clock is turned off during the first part of the cycle in which the first data part is received. This standby period is timed by a less accurate but lower power low frequency clock. The high frequency clock is turned on at the end of the timed period and operates during a second period while the second data part is being received. The error in the timing of the turning-on of the high frequency clock is determined and compared with a threshold. If the timing error is below the threshold, the high frequency clock is again turned off at the end of the second period for the next standby period. If the timing error is greater than the threshold, the high frequency clock is left running until the end of the second period in a later cycle. By this means correct reception of paging signals is not impaired by excessive error in the time at which the high frequency clock is turned on. |
