The USC 760XLT has 100 memory channels, each of which can be pro-
grammed to store one frequency. The channels are divided into
banks, useful for storing similar fre- quencies in order to maintain faster scanning cycles. When scan ispressed, each of the programmed frequencies within a selected bank will be sampled for a transmission (locked channels will be skipped} at the rate of about 15 channels per second. If an active fre- quency is found the unit will stop and monitor that frequency until there is no
longer any activity. A two second delay can be added to each channel and will
allow the unit to monitor the frequen-
cy for a return or continued transmis- sion. If, after two seconds, the fre-
quency remains inactive, the scanning cycle will resume.
When the unit is first turned on, each channel will contain "000.000". When
new frequencies are programmed, the old will be erased. Ifan invalid frequen- cy is entered, "Error" will be displayed and the old frequency will return. "E
Loc" will also be displayed if memory lock is on.
To operate the scanner make sure that
the power is correctly connected to the unit. Turn the volume control on and
adjust the desired level. Adjust the squelch by turning the knob fully
clockwise until a rushing sound is heard. Turn the knob back until the re-
ceiver issilent. After the channels have been programmed, operation issimple. Press the scan key to scan all the chan- nels, press the manual key to stop the
scanning, and manually step through the channels.
Note: The unit must be in the scan mode to select or deselect a channel
LCD Display
The USC 760XLT has a backlit display which shows the current channel and
frequency as well as other operational modes. When the unit isscanning, the channel number will rapidly advance while the frequency display will go blank. When the scanner is stopped the current channel and frequency will again be displayed.
When frequencies are programmed the display will show the digits as they are entered. The display will also show "PRI"when the priority mode is on, "LI 0" whenever a channel appears that has been locked out, and "DLY"when- ever a channel has been programmed for delay. In the upper left hand corner of the display the numbers
lected during the scan sequence by the use of the numeric pad.
Programming
Toprogram a frequency into a channel, press the digits of that frequency in- cluding the decimal point and then press the enter key. If an invalid fre- quency is entered, the display will
show "Error." To change a frequency enter the new one and the old one will
be erased.
