perform the following safety check before releasing
the set to the customer:
Check the antenna terminals, metal trim, “metallized”
knobs, screws, and all other exposed metal parts for
AC leakage. Check leakage as described below.
LEAKAGE TEST
The AC leakage from any exposed metal part to
earth ground and from all exposed metal parts to any
exposed metal part having a return to chassis, must
not exceed 0.5mA (500 microampers). Leakage
current can be measured by any one of three
methods.
1. A commercial leakage tester, such as the
Simpson 229 or RCA WT-540A. Follow the
manufacturers’ instructions to use these instru-
ments.

Precision 245 digital multimeter is suitable for
this job.

analog meters must have an accurate low-
voltage scale. The Simpson 250 and Sanwa

is suitable. Nearly all battery operated digital
multimeters that have a 2V AC range are
suitable. (See Fig. A)

When the interval is changed, all preset stations which you
have stored will be erased. After changing the interval, be
sure to newly preset stations. (See “Presetting Stations” on

The STR-02010 incorporates a digital signal processor which
consists of digital parametric equalizer, digital surround
processor, and the DDS (Digital Dynamic Sound).
The parametric equalizer controls the output level of the
desired frequencies, and the sorround processor
electronically reproduces a natural sound field for various
kinds of music. The DOS system provides powerful sound
even at small output levels.
By using these three digital sound effects, you can create a
optimum sound quality and sound atmosphere in your room.
