CAUTION
This set employs a microcomputer to control frequencies, operating mode and display.
The microcomputer has a program to initialize the operating condition of the set. However, some-
times an abnormal figure may be displayed on the display, or the display fails to illuminate.
This may be caused by an intermittent connection of the power plug or the power switch being
turned OFF and ON to quickly.
This is not an equipment malfunction. When this occurs, it may be solved with the following
simple procedure:
Turn OFF the set's power switch.
If the set has a memory switch, turn OFF this switch also.
If you use a memory backup power supply, unplug its power connector.
Unplug the power plug of the set.
Wait at least 45 seconds and reconnect the power plug to the set.
Turn ON the power switch.
Make sure the set has the correct startup readout.
(If not, repeat the above procedure.)
8. Turn ON the memory switch (when the set has one), connect the memory backup power
connector (when used).
