JRC JRL-2000F - Write-Protecting for Preset Data; Using the JRL-2000 F as a Dummy Load

SPECIAL OPERATIONS 7
1 7.2 Write-protecting Preset Data
The preset data stored during automatic tuning operations can be protected against inadvertant
erasure or changes by locking the switch. This makes it impossible to implement the
automatic tuning operation.
To perform this operation:
@ Turn off the lPoWERl switch.
@ While holding down the switch, turn the lpoWERl switch on. The switch
will now be locked
To undo this operation, simply repeat the above steps.
7.3 Using the JRL-2000F as a Dummy Load
The JRL-2000F can be used as a dummy load with an input resistance of 100 W. The operable
frequency range is
1.8-30 MHz.
To activate the dummy load setting:
@ Turn the lPoWERl switch off.
@ While holding down the (PAI switch, turn on the switch. a is blinked
in the central display and the
JRL-2000F functions as a dummy load for the exciter
until the
lpoWERl switch is turned off. When turned on again, the JRL-2000F returns
to normal operation.
