7.2 Check each active channel on the RTM500 Interface Card in turn and witness
a number of vehicles passing over the location of the sensor to verify that
there are corresponding detection events registered on the red detect LED
on the channel under test.
7.3 If some vehicles are not being detected or if a channel appears to be too
sensitive, then the sensitivity settings should be adjusted to improve vehicle
detection. The sensitivity settings are adjusted using switches S1 and S2 on
the front panel and the settings indicated on the product label or in section 6
above. Once a new sensitivity has been selected for the channel of interest,
a full reset must be performed by pushing and holding in the reset button for
greater than 3 seconds.
