UNPACKING
Yorkie ships with a charging dock, AC adapter, omni-directional SMA antenna and the Yorkie receiver all in a hard carrying case.
POWERING UP/DOWN
Yorkie only has one physical button on the front of unit. Press this white button to power up and hold it down for 3 seconds to power
down.
CHARGING
Yorkie ships with an AC powered charging dock. Place unit in charging dock and be sure the red LED on top of unit in ON. If red LED is
not ON, Yorkie is not being charged. Try adjusting Yorkie in dock until red LED is ON. Charging takes approximately 4-5 hours. Yorkie
runs approximately 4 hours from a full charge. Yorkie may be operated while it is charging but this will heat up the unit and increase
charging time substantially so it is not recommended for regular use. If you prefer to operate Yorkie while it is also being charged, be
sure to turn on the dual cooling fans using the power switch on the rear of charging dock. Yorkie has smart trickle charging circuity that
is always calibrating the battery but if your battery runtime is noticeably short after a full charge, you may need to manually calibrate
the battery. Go to BATTERY under MAIN MENU for more details and consult BVS support.
OPERATION
Yorkie chooses the strongest cell phone signal nearby and “locks” onto that phone as it continues to scan the remaining RF bands. As the
signal strength increases (or you approach the signal source), Yorkie will vibrate more frequently. If you are using Yorkie in a “noisy”
RF environment, try raising the threshold level to decrease the amount of detection triggers and vibrations. If you are not detecting
anything, try lowering the ATTENUATION in the OPTIONS menu. You should see a blue bar on the left rise as you lower the attenuation
further. Always start measurements with attenuation set at 0 dBm. For more information on typical detection ranges and environments,
see included Yorkie data sheet or consult your BVS sales engineer.

MAIN MENU
Choose sub-menus from this
screen. The yellow arrow on the
top left of every screen will re-
turn to the previous screen.
SELECT COUNTRY
Choose the country of origin for the phone(s) you are trying to detect.
Yorkie is set to United States by default. If your country is not listed,
check with your BVS support representative for more information.
PRODUCT INFO
View rmware version installed
and your unit’s serial number.
OPTIONS
All measurement options with
‘SET’ choices will take you to
additional screens except for ‘VI-
BRATOR’ which is toggled ON by
default.
CALIBRATION
View remaining battery power in
this screen. Tap screen to begin
battery calibration procedures.
WATERMARK
SET reset time for watermark
peak level or ‘MANUAL’ which
resets when users tap on main
measurement screen.
ATTENUATION
Tap up / down on yellow arrow
to raise / lower attenuation
from 0 to 30 dB. Lower the at-
tenuation (increases sensitivity)
to detect faint signals and raise
attenuation to lower sensitivity
of overly strong RF signals.
STEALTH MODE
This mode keeps the screen mini-
mized and dim for covert opera-
tions. Vibration is ON by default.
Tap screen anytime to exit mode.
