Note:
When the EPROM is removed, stored call records,
alarm clues, and configuration data may be lost. Prior
to removing the EPROM, it is recommended to poll
any stored data and save configuration parameters.
1. Remove the PBX Cable(s) from the PollCat III.
2. Retrieve stored call records from the PollCat III. Save
currently defined configuration parameters as described in
Section 8 of the PollCat III User's Guide.
3. Power OFF the PollCat III and remove the power cable from
the unit. Remove the instrument Top Cover.
4. The EPROM can be found at board location U6, as shown in
Figure 2.3. Use a chip puller or a small, flat tip screw driver
to carefully remove the EPROM from its socket.
Note:
·
When using a screw driver, gently pry up one end of
the EPROM and then pry the other end in a rocking
motion.
·
Do not attempt to pry the socket from the PCBA or
allow the screw driver to make contact with the main
logic board.
