7. OPERATION
IMPORTANT
• Do not turn off the power to the transmitter
immediately after completion of the change in
the LRV and/or HRV setting(s). Note that
powering off within thirty seconds after setting
will cause a return to the previous settings.
• Changing LRV automatically changes HRV to
the following value.
HRV = previous HRV + (new LRV – previous LRV)
• If the range-setting push-button and external
zero-adjustment screw are not touched during a
range-change operation, the transmitter auto-
matically switches back to the normal operation
mode.
