Servicing And Upgrade Matrix; Table 1 Possible Solutions To Common Faults And Issues - FUTABA 9z User Manual

2.2. Servicing and Upgrade Matrix

You can use the following tables to navigate this manual, solve specific issues or fix
faults with your 9Z. Table 1 shows some common faults and issues and the possible ID
of the solution in Table 2. Table 2 below provides a matrix of the service and upgrade
procedures detailed in this manual, the tools required to perform them and the level of
difficulty (refer to the key below the table for an explanation of the symbols). I've rated
the level of difficulty based purely on what level of skill I think is needed if the correct
"recommended" tools for the job are used. You can get by without the correct tools for
many of these procedures, but the level of skill required will be significantly increased.
