SERVICE PROCEDURE
1. Replacing the fuses
EE This symbol located near the fuse indicates that the
fuse used is show operating type, For continued protection against
fire hazard, replace with same type fuse, For fuse rating, refer to
the marking adjacent to the symbol.
EE Ce symbole indique que le fusible utilise est e lent.
Pour une protection permanente, n'utiliser que des fusibles de meme
type. Ce demier est indique la qu 1e present symbol est apposre.

2. To initialize the unit
1. Press and hold down VIDEO 1 button, then press STANDBY/ON button when the unit is Power on.
2. After " Clear " is displayed, the preset memory and each mode stored in the memory are initialized and will
retum to the factory settings, and turn to Standby mode.
3. Safety check out
(U.S.A. model only)
After correcting the original service problem, perform the following safety check before releasing the unit to
the customer.
Leakage current Check
Measure the leakage current to a known earth ground (water pipe or conduct etc.) by connecting a leakage current
tester between the earth ground and exposed metal parts of the unit (input/output ground terminals, screw heads or
metal overlays etc.).
Plug the power supply cord directly into a lZOVac 60Hz wall socket and turn STANDBY button on.
Any current measured must not exceed 0.5mA.
4. Memory Backup
This model uses a battery-less memory backup system in order to retain radio presets and other settings
when it's unplugged or in the case of a power failure.
Although no batteries are required, the unit must be plugged into an AC outlet in order to charge the
backup system. Once it has been charged, the unit will retain the settings for several weeks,
although this depends on the environment and will be shorter in humid climates.

Bypass PLL for CIk48M. Normally, this pin is
a no-connect, and the internal pullup ensures
that the PLL is enabled. To bypass the PLL,
set /BprLLCIk48M = O, and supply a 48.0
MHZ clock to the C|k48M pin.

receiving that same clock through its input
buffer. To bypass the PLL, set
/BprLLC|k54_72M = 0, and supply a 54.0
or 72.0 MHz clock to the Clk54_72M pin. »
