Safety regulations require that after a repair, the set must be
returned in its original condition. Pay in particular attention to
the following points:

Route the wire trees correctly and fix them with the
mounted cable clamps.
Check the insulation of the AC Power lead for external
damage.
Check the strain relief of the AC Power cord for proper
function.
Check the electrical DC resistance between the AC Power
Plug and the secondary side (only for sets which have a AC
Power isolated power supply):
1. Unplug the AC Power cord and connect a wire
between the two pins of the AC Power plug.
2. Set the AC Power switch to the "on" position (keep the
AC Power cord unplugged!).
3. Measure the resistance value between the pins of the
AC Power plug and the metal shielding of the tuner or
the aerial connection on the set. The reading should be
between 4.5 Mohm and 12 Mohm.
4. Switch "off" the set, and remove the wire between the
two pins of the AC Power plug.
Check the cabinet for defects, to avoid touching of any
inner parts by the customer.
