CAUTION
WA NING - Maximum input voltage is 12VDC. Automotive voltages may exceed 12V causing dam-
age to internal circuitry. Damage resulting from excessive input voltage is readily apparent and will not
be covered under warranty. Units returned for warranty service that have damage resulting from exces-
sive supply voltages will incur service charges.
WA NING - Maximum antenna input signal is +15dBm (50mW). Under no circumstances should the
Cub be directly connected to an RF transmitter or be used in close proximity to a radio transmitter of more
than 5 watts. Damage to the input amplifier circuitry is readily apparent and will not be covered under
warranty. Units returned for warranty service that have damage to the input circuitry will incur service
charges.
This manual covers connection and operating instructions for the
Optoelectronics Cub. The Optoelectronics Cub is covered under U.S.
Patent Number 5,471,402.

POWE ON/OFF
Move the slide switch up to turn the Cub on.
ANGE 2.8GHz/250MHz
To count from 1MHz-2.8GHz slide the switch up to the 2.8GHz setting. To count from 1MHz-
250MHz only slide the switch down to the 250MHz setting.
FILTE /CAPTU E/NO MAL
Slide the switch up the Filter/Capture setting to activate Filter mode. Press the gate button to activate
Capture mode. Move the slide switch down to ormal setting to put it in ormal mode.
A M/GATE
Press the Arm/Gate button to increase or decrease the display resolution. Press the Arm/Gate button
when in Filter mode to activate Capture mode.
Antenna
50 Ohm B C connector. Do not exceed +15dBm (50mW) signal to the antenna input. Please see our
catalog or web site for antenna options. www.optoelectronics.com
9-12VDC
The connector labeled 9-12VDC on top of the Cub is used for accepting the plug from the supplied
AC90 power adapter. The AC90 is a nominal 9VDC adapter. Plug the AC90 into the Cub to charge
the unit. A full charge will take approximately 8-10 hours. The Cub will operate approximately 4-5
hours on a full charge.

Charging the Cub
Plug the supplied AC90 adapter into the top of the Cub for 8-10 hours to fully charge the battery pack.
The unit should operate for 4-5 hours on a full charge. The unit may be turned on while the AC adapter
is plugged in. Charging will occur with the unit on or off. If the battery becomes discharged a battery
symbol with a line through it will be displayed on bottom of the display.
Selecting a range
The two ranges are as follows:
250MHz (switch down) for frequencies between 1MHz-250MHz
2.8GHz (switch up) for frequencies between 10MHz-2.8GHz
The 2.8GHz range covers all VHF and UHF communications. Leaving in this range may prove to be
the most useful.
Selecting the 250MHz range is good if you require to count signals below 250MHz. The other advan-
tage to this range is that it is faster to respond and gives more digits of resolution than in the 2.8GHz
range.
Using the Normal/Filter-Capture switch
When the switch is in the ormal mode position the display will oscillate. The only time the display
becomes stable is when the unit is actively counting a signal. When the carrier drops then the display
begins to oscillate again displaying random background RF.

Operation cont.
When the switch is in the Filter/Capture setting the display no longer oscillates. When in filter mode
the display will display the word FILTER at the top of the display. In filter mode only real measure-
ments are displayed. The frequency will be displayed on the display even after the carrier is gone. If
the unit captures another signal then it will over right the last frequency displayed.
To place the unit in capture mode press the Arm/Gate button when the unit is in Filter mode. The unit
will display the word CAPTURE and it will also flash. When a frequency is captured in capture mode
the frequency will lock on the display and cannot be over written by another frequency. The only way
to clear the display is to move the switch down to normal mode and then back up to filter/capture mode.
Repeat the process above to go from filter to capture mode.
Selecting a gate time
In normal mode press the arm/gate button to change the measurement time. A longer gate time means
counting for a longer period of time and results in more digits displayed. The available gate times are
shown on the following page.
