JRC JRL-2000F - 7 Special Operations; 7.1 Erasing Preset Data

7 SPECIAL OPERATIONS
This chapter describes special operations of the JRL-2000F, which are not normally used during
everyday operation..
Erasing Preset Data
The preset data stored during automatic tuning operations can be erased from memory by
following the following procedures
7.1.1
Erasing all data for a selected antenna
All matching data for a specified antenna switch setting can be erased from memory.
In other words, if antenna
1 is selected to execute erasing, all preset data stored
for antenna
1 are erased. Data for other antennas remain unchanged.
To perform this operation:
@ Turn the lPoWERl switch off.
@ Press the switch for the antenna whose preset data you wish to erase (1, 2, 3
or 4).
@ While holding down the selected antenna switch, press the lpoWERl switch to turn
the amplifier on. The antenna switch should be held down until the frequency
indicated in the central display begins to blink.
7.1.2 Erasing all data for a selected frequency band
All matching data for a specified antenna in a single sub- band can be erased from
memory. In other words, if antenna 1 is selected to execute erasing and the
JRL-
2000F is currently tuned to the first sub-band for 20 meters (14.000 to 14.080 MHz),
all preset data stored for antenna 1 and that sub-band are erased. Data for other
antennas and sub-bands remain unchanged.
To perform this operation:
@ Turn the pmiEq switch on.
@ Press th Po meter switch.
@ Press the switch of the antenna whose data you wish to erase (1, 2, 3 or 4).
@ Implement the
operation at a frequency within the sub-band whose you wish
to erase. Verify the frequency band indicated in the central display.
@ While holding down the antenna switch, press the ( switch. These two switches
should be held down until the frequency band indicator in the central display begins
to blink.
