Pour une protection permanente, n'utiliser que des fusibles de meme
type. Ce demier est indique la qu le present symbol est apposre.
2. To initialize the unit
1. Press and hold down
VCR/DVR button, then press ON/STANDBY button when the unit is powered on.
2. After "C l e a r " is displayed, the preset memory and each mode stored in the memory are initialized and will
return to the factory settings, and turn to Standby mode.
3. Safety check out

<Notes>
Canadian model<MDC>:
(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 120Vac 60Hz wall socket and turn ON/STANDBY button on.
Any current measured must not exceed 0.5mA.
This model uses a EE-PROM IC in order to retain radio presets and other settings. So, memory contents will be
kept eternally with no care.
4. Memory Backup
3. Remove the AC cord from power line.
