FIELD SERVICE BULLETIN

FSB Number: LVCCFSB2004-132
Author: Daniel Arndt
Date: October 1, 2004
Total No. of Pages: 3
Subject: CDMA T7xxc Hang-Up Cup for Pro-Install Car Kits
Model Affected: All CDMA T720c, T730c, T731c, T732c HUCs
Level of Repair: All

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”.

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:

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.

customer’s HUC with the new version (See Table 1).
