2.4 Precautions
Connect the receiver only to a power source described in this manual.
Take care when plugging in cables, avoid applying sideways pressure that might damage the
connectors.
Avoid operating in wet conditions.
For better performance and safety, connect the receiver to good earth ground using a short,
heavy, braided cable.
Ground all outdoor antennas for this receiver using approved methods. Grounding helps protect
against voltage surges caused by lightning. It also reduces the chance of build-up of static
charge.

Keep pressed the key to enter the “QuickMem” mode.
The memory channels 180 to 199 are reserved for the “QuickMem” selection. Keep pressed the key
until the desired frequency appears on the LCD display, then release the key and the current VFO is set
to the frequency and mode saved in the memory channel.
You can use the “FDM-DUOr Manager” feature in the ELAD FDM-SW2 software to customize the
memory channels.
6.1.7 VFO-A = VFO-B
With long pressure on key you get VFO-A = VFO-B

memory menu. In this menu it is possible to modify the selected memory frequency in digit by digit
mode.
Use the button to select the VFO-A/B. This is useful if you want to set the memory settings to a
specific VFO.
6.2.2 Delete a memory
Apply a long pressure to the key to enter the delete menu
Use the E2 knob to set yes or no and make a short pressure on E2 to confirm.
6.2.3 Set memory to VFO
Use the key to set the selected VFO to the selected memory frequency and mode. When this
function is used, the FDM-DUOr automatically switches to the VFO mode.
