Preliminary Troubleshooting Procedure - Motorola V60 Series Manual

4.4 Preliminary Troubleshooting Procedure

1. Verify the Problem
Assure that the problem is not due to operator error. It is important that the operator is familiar
with how the telephone package functions. Refer to the owner's manual for specific phone
function capability.
2. Verify that the Handset is the Correct One for the Customer's Coverage Area
Handset part numbers are carrier dependent. If the part number of the handset does not
correspond with the carrier specific number, the phone will not function properly and will appear
to be defective. Refer to the parts department to find the correct handset type (CDMA or
TDMA), and carrier specific part number for the customer's carrier preference.
The part numbers can also be found on the web at:
provided by Motorola and is intended for dealer use only. The site is password protected. Enter
"mbusa" for the "User Name" entry, and "k2option" for the "Password", both entries need to
be in lower case letters, and then select "O.K.".
3. Assure that the Handset is Programmed Correctly
Assure that the phone is properly programmed and activated. If the customer is switching cell
service from analog to digital, inform the carrier that the new phone is digital to avoid activation
problems. Make a test call to verify that the carrier has activated the phone, and that it has been
programmed correctly.
4. Assure that the System is Installed Properly
Inspect the installation of the system. Assure that all component connections and wiring
connectors are properly connected. Assure that the Compensator has not been installed
backwards (reversed in the antenna line).
5. Check Applicable Fuses
Assure that all fuses are good. In addition to checking the fuses for the phone system, other
vehicle systems which interface with the telephone package might have a blown fuse, such as the
radio, etc, which would affect the operation of the phone functions. If a fuse is blown, determine
the cause to eliminate the problem from reoccurring.
6. Signal Quality
If the problem is poor signal quality, assure that it is not a carrier problem. Eliminate the
possibility of a cell site malfunction or other carrier related anomaly by calling the customer's
carrier to verify that they are not experiencing technical problems. A bad signal could also be the
result of the operator being outside of, or on the edge of, a carrier provider's coverage area.
