Memory Programming

Introduction - The Xcom760 has 99 user programmable memory channels, stored
in non-volatile memory. The memory channels can be programmed via the keypad
or via the RS 232 data link (using the serial port and windows based software). This
section deals with the keypad entry method, refer to the XCOM760.com website for
software downloads and interface details.
Operation - To enter the memory programming mode press and hold in for 3
seconds the MEM key. The MEM icon will blink during the programming procedure.
Note: blinking digits indicate current changeable value; e.g. blinking 123 indicates
that the MHz value can be changed.
The F/CH control allows scrolling, simply push it in to select and rotate the values,
the action for this moves clockwise, starting at the CH value, this selects the
channel number which is 0 to 99, press once to select the rotate value mode, by
turning right (up) or left (down) the channel number will change, make sure you
accidentally do not erase a channel that is already programmed (to check simply go
back to the main screen by hitting the ) and then enter the memory screen by
pressing the MEM button). Once you are happy with the Channel number press the
F/CH control in again, this will then select the MHz, press in again to change this
value. If the Vor or Gen options are enabled (see OPERATION, MODE for procedure)
then these receive only frequencies can be entered as well, if these options are
subsequently disabled, then the entered frequencies will still be in the memory
allocations, as these are independent of any other mode selections. Press in the
F/CH again and this will then move you on to the KHz display, press the F/CH to
activate scroll and now rotate the F/CH to select the desired KHz frequency. If you
press the F/CH again it will bring you back to the CH display. When you are
satisfied that the correct channel is programmed press and hold the MEM in for 2
seconds. The word will be displayed for 3 seconds. To program the full 99
channels simply repeat the procedure, when you wish to return to the main screen
simply press the . If you want to clear the memory area then at start up press
both the ON and MEM buttons together, this will erase the FULL 99 channel
allocations, irrespective of how many are programmed. The above programming
and erasing feature can also be done via the RS 232 port, using the free XCOM760
utility from the xcom760.com website.
