14、ing of frequency counter becomes 524.288 kHz+/-1Hz. 4. Memory Preservation This unit does not require memory preservation batteries. A built-in memory power back-up system preserves the contents of the memory during power failures and even when the unit is unplugged. The unit must be plugged in orde

15、r to charge the back-up system. The memory preservation period after the unit has been unplugged varies depending on climate and placement of the unit. On the av erage, memory contents are protected over a period of a few weeks after the last time the unit has been unplugged. This period is shorter

16、when the unit is exposed to a highly humid climate. 2. To initialize the unit This device employs a microprocessor to perform various functions and operations. If interference generated by an external power supply, radio wave, or other electrical source results in accident which causes the specified

17、 operations and functions to operate abnormally. To perform a result, please follow the procedure below. 1. Press and hold down the MEMORY button, then press the DISPLAY button. 2. Press the STANDBY/ON button. After clear is displayed, the preset memory and each mode stored in the memory, such as su
