Important Safety Notice

Many electrical and mechanical parts in this chassis have special safety-related characteristics. These parts are identified by in the Schematic Diagram and Replacement Parts List. It is essential that these special safety parts should be relpaced with same components as Recommended in this manual to prevent Shock, or File, or other Harzards. Do not modify the original design without permission of menufacturer.

Leakage Current Hot Check (See Below Figure)

Plug the Ac cord directly into the Ac outlet. Do not use a line Isolation Transformer during this check. Connect 1.5k/10 watt resistor in parallel with a 0.15uF capacitor between a known good earth groung (Water pipe, Conduit, etc) and the exposed metallic parts. Measure the AC voltage across the resistor using AC voltmeter with 1000 ohms/volt or more sensitivity. Reverse plug of the AC cord info the AC outlet and repeat AC voltage mresurements for each exposed metallic part. Any voltage measured must not exceed 0.75 volt RMS, which is, corresponds to 0.5mA. In case any measurement is out of the limits specified, there is possibility of shock hazard and the set must be checked repaired before it is returned to the customer.

REMOTE CONTROL UNIT

BA TTERY INSTALLATION

Replace two batteries in the battery compartment at the same time. lnsert "AAA" batteries, observing the polarity ( or ) marked on the unit.

Batteries should last about a year under normal use. lf the operation is unstable(either channel or volume does not change), replace the batteries. When the hand unit is not used for a long, or when the batteries are used up, take out the batteries to prevent possible leakage. To avoid any malfunction of the remote control, press only one button at a time.
