Noise Floor Level Indication

The Snoop contains an indicator that provides feedback as to
the device noise floor. The noise floor of the instrument will
vary depending upon other off-air signals it is subject to. The
lower the noise floor, the lower level leak Snoop will be able to
detect. To keep the display screen uncluttered, units are not
shown – but they are in µV/m, where for example a 1 would
correspond to 1 µV/m. This number would correspond to a noise floor level of -
60dBmV/m using the convention employed in the Navigator Plus. The lower the
indicated noise floor, the better the sensitivity of the device. If noise floors are
relatively high, then a recommendation would be to change to a different frequency
containing less terrestrial noise.

Auto shutdown counter

When Auto start is enabled – when power is removed
from the device while cradled, the unit will begin a five
minute countdown to shut down the device. No action is
required of the user, the message is informational. To
stop the countdown and use the device, press enter.

Other battery saving features

There are two additional battery saving features. First is that the display backlight
will turn off if no buttons on the snoop have been pressed for one minute. Simply
press the power button one time to turn the backlight on. Second, when the unit is
cradled and unused for two hours, it will automatically power down.

GPS status indicator

There are four possible GPS conditions that can be indicated on the screen:
GPS –NO - This is the condition the unit is in when it is initially turned on and the
unit is waiting for GPS lock. Leak detection in QAM detector mode is not possible
