DISASSEMBLY
(Follow the procedure below in reverse order when reassembling)
Note: This system has a feature to back-up various settings such as function selected, volume level, etc. By performing
disassembly or checking of the system, this back-up function can be a cause of error, and the system may not work
normally when power on after re-assembling.
To avoid this error, short-circuit both leads (+ and - terminals) of C110 on 1U-3398-1 (Main PWB) for more than 60
sec., and check that the voltage between the terminals is lowered less than 1V before re-assembling. (The back-up
function is deactivated and various settings are reset to factory settings, default values, if short-circuited.)
