Operating the VNS-41A
1. Set the FUNCTION SELECTOR to ON.
2. If these are not the desired frequencies, rotate the FREQUENCY KNOBS until the desired frequency
is displayed on the bottom portion of the display
3. Press and release the FREQUENCY TRANSFER button. This exchanges the two displayed
frequencies. The desired frequency is now active and may be used immediately.
4. Adjust the VOLUME CONTROL for the desired audio level.
5. Rotate the FREQUENCY KNOBS until the desired standby frequency appears on the bottom portion
of the display.
NOTE:
To tune the active frequency only (without first tuning the standby and then "flipping" the
frequencies), press and hold the FREQUENCY TRANSFER button for two seconds, then
release it. This temporarily removes the standby frequency from the display.
Now the FREQUENCY KNOBS may be used to change the active frequency. The active
frequency may be used immediately.
To restore the standby frequency to the display, press and hold the FREQUENCY
TRANSFER button two seconds.
