Problem

Service is aware of a problem with the Hang-Up Cup (HUC) for the CDMA T7xx series phones. If the user allows the phone to self-align when inserting into the HUC, the RF Connector on the HUC could cause damage to the RF Connector (J10) on the CDMA T7xx series phone. This results in complaints of “No Service when removed from Car Kit”.

Figure 1. This X-Ray picture shows a good J10. The “wiper” reaches across to the fixed contact.

Figure 2. This

X-Ray shows a damaged J10. The movable contact (right) is bent so that the “wiper” no longer reaches the fixed contact (left).

Figure 3. This J10 shows visible signs of damage. Note the elongation of the hole to the lower right.

Solution

Design changes have been made to the HUC to avoid damage to the RF Connector during insertion. The mating angle of the RF Connectors has been changed so that the connectors will better align at initial contact, thus preventing damage to J10.

Service Action

Customer Returns:

Level 1 and 2. When a customer complains of “No Service” or “Poor Service” on a CDMA T7xx series phone, inspect J10 immediately. If J10 is damaged, determine if the unit is used with a Pro-Install Car Kit. Make arrangements with the customer for replacement of the HUC with the new version (See Table 1), and send the phone to a Level 3 (or higher) facility for repair.

Level 3 (or higher). When a customer complains of “No Service” or “Poor Service” on a CDMA T7xx series phone, inspect J10 immediately. Replace J10 if it is damaged. If the phone is used with a Pro-Install Car Kit, in addition to replacing J10, also replace the customer’s HUC with the new version (See Table 1).

Service Inventory:

Use old parts (See Table 1) to depletion on GSM products. Please use only new parts with CDMA products.
