SERVICE WARNING : DO NOT APPROACH THE LASER EXIT WITH THE EYE TOO CLOSELY. IN CASE IT IS NECESSARY TO CONFIRM LASER BEAM EMISSION, BE SURE TO OBSERVE FROM A DISTANCE OF MORE THAN 30cm FROM THE SURFACE OF THE OBJECTIVE LENS ON THE OPTICAL PICKUP BLOCK.

Laser Diode Properties Material: GaAS/GaAlAs Wavelength: 780nm Laser output: max. 0.5mW* Emission Duration: continuous *This output is the value measured at a distance about 1.8mm from the objective lens surface on the Optical Pickup Block.

LASER WARNING LABEL
The labels shown below are affixed. 1. Warning label
DANGER:
INVISIBLE LASER RADIATION WHEN OPEN AND INTERLOCK FAILED OR DEFEATED. AVOID DIRECT EXPOSURE TO BEAM.

F901 PART NO. 252157 252083 DESCRIPTION 1.25A-UL/T-237, Fuse 0.4A-SE-EAW, FUSE NOTE : : 120 V model only : 230 V model only

2. To initialize the unit
1. Press and hold the MEMORY button and press the DISPLAY button. All segments light up. 2. Press the STANDBY/ON button. When " CLEAR " appears on the display, the preset memory and each mode stored in the memory are initialized and will return to the factory setting.

3. Safety-check out
(Only U.S.A. model) After correcting the original service problem perform the follwing safety check before releasing the set to the customer Connect the insulating-resistance tester between the plug of power supply cord and terminal GND on the back panel. Specifications: More than 10Mohm at 500V

4. Memory Preservation
This unit does not require memory preservation batteries. A built-in memory power back-up system preserves the contents of the memory during power failures and even when the unit is un-plugged. The unit must be plugged in order to charge the back-up system. The memory preservation period after the unit has been unplugged varies depending on climate and placement of the unit. On the average, memory contents are protected over a period of a few weeks after the last time the unit has been unplugged. This period is shorter when the unit is exposed to a highly humid cli-mate.

5. Changing the AM band step
With the exception of the worldwide models, a tuning step selector switch is not provided. When you change the band step, change the parts as shown below. To 10kHz 3.3k 5.6k To 9kHz 10k open
