1. Check all cables for cut's or breakage.
2. Make sure the AC and Telephone cable connectors are firmly attached to their cords and are
not broken. Also check that any connector pins are not bent.
3. Check Power Connector Jack at the back of the PRU+. The Power Jack should be flush with
the outside case and should not move when pulled upon. The Power Jack should also have
one copper pin inside each of the two sections of the connector.
4. Check Telephone Connector Jacks at the back of the PRU+. The Two Telephone Jacks
should be aligned with the two holes in the back of the PRU+ and should be clear of any
foreign material. Remove any foreign material found if possible. If the foreign material can not
be removed send the unit back to STRATEGIC for repair.
5. If a PRU+ is dirty or has any foreign substance on it, wipe the entire PRU+ with a damp cloth.
If the dirt is still attached take isopropyl alcohol and rub to remove. If Isopropyl Alcohol is not
available, spray the PRU+ lightly with Lysol to disinfect.
6. Check the screw plugs underneath the PRU+ for pry marks or gouges. The screw plugs are
located next to the rubber feet at the back of the unit and on the raised ledge at the front of the
unit. (See Figure 4 : Underneath a PRU+)
