2. Safety-check out
(Only U.S.A. model)
After correcting the original service problem perform the
following 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
The TX-SR502/TX-SR502E 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
TX-SR502/TX-SR502E must be plugged into an AC
outlet in order to charge the backup system.
(On non-American models, the TX-SR502/
TX-SR502E's POWER switch must be set to ON in
order to charge the backup system.) Once it has been
charged, the TX-SR502/TX-SR502E will retain the settings
for several weeks, although this depends on the
environment and will be shorter in humid climates.
5. Memory backup
6. Setting the voltage selector
(Worldwide models only)
The Worldwide model has a voltage selector for compatibility with power
systems around the world. Before you plug in this model, make sure that
the voltage selector is set to the correct voltage for your area. If it isn't,
use a small screwdriver to set it as appropriate. For example, if the voltage
in your area is 120 volts, set the selector to "120V. " If it's between
220 and 230 volts, set it to "220-230V. "
Main microprocessor Q7008.
