Pressing the Up/Down switch (in either direction) will toggle the display to:
__________________
_MODIFY REMOTE _
__________________
When the display indicates the configuration (local or remote) to be modified, press the
Program/Execute switch.
2.Status of the selected configuration will be displayed. For example:
__________________
_L 6.60MHz ON _
__________________
The display consists of:
An initial letter indicates Local or Remote.
The current frequency setting.
The current ON/OFF status.
3.By using the horizontal rocker switch the cursor can be moved left or right to either the
ON/OFF position or to any digit of the frequency.
A.If ON/OFF is selected, the status can be modified by operating the vertical switch. This
will alternately turn the channel on or off.
B.If changes are desired in the frequency, move the cursor to the digit that you wish to
modify. By using the vertical switch, that digit can be raised or lowered by the direction of
the arrow. The cursor can then be moved to another digit and the action repeated until the desired
frequency is displayed.
NOTE:
The modified frequency and ON/OFF condition will not become effective until the final
operation of the Program/Execute switch described in the next paragraph. To prevent
interruption of other channels when a frequency change takes place, the 455
automatically mutes the carrier until the phase locked loop frequency synthesizer has stabilized
at the new frequency.
