4 – Trouble-Shooting
1. Status: The LED on the back of the DU and CU display information regarding the
SpotCell system during operation.
Action: A red LED indicates a fault condition, a yellow LED indicates an overdrive
condition, and blue indicates power on, no faults. A green LED on the CU indicates
reduced coverage due to a signal isolation condition.
2. Status: The LED on the DU is not illuminating.
Action: Ensure the following:
 The cable from the DU is connected to the CU port labelled .
 The power supply is connected to the CU or BIAS-T (power inserter).
 The power supply is plugged into an electrical outlet.
 The display has not timed out. Cycle the power off/on to re-activate the display.
 If the LED is still not illuminating, contact technical support.
3. Status: My cell phone does not work around the location I would like to install the
SpotCell DU.
Action: Try positioning the DU externally as high as possible.
4. Status: The DU and CU are installed properly, but your cell phone only works in
close proximity to the CU.
Action: There are three factors that may be affecting coverage as described below:
 Visually inspect the area around the CU. Ensure that there are not any large
metallic objects directly between the CU and the area where cell phone coverage
is not adequate. Remount the CU so that it is out in the open.
 If the signal the DU is receiving is very weak (although still strong enough to allow
operation), the area around the CU within which a cell phone can function will be
relatively small. An effort can be made to improve system performance by raising
or otherwise repositioning the DU in an effort to obtain a stronger signal.
 check with your vendor that your SpotCell product is compatible with your cell
phone service.
