Safety Check after Repairs
Perform the insulation resistance test for the security of
the product, after repairs.
■ Point to be checked
Check that the power supply plug does not have poor
contacts and that there is no garbage or conductive materi-
als stuck between the terminals. If the power supply cord
is damaged, do not repair it using tape; replace it with the
specifi ed part.
■ Safety study
After repairs have been completed, remove the power
supply cord from the outlet, the antenna, the outside con-
nection cable, etc., and insert the power switch. Using a
500V DC insulation resistance meter, check the insulation
between each terminal of the attachment plug and the an-
tenna terminal and other outside metal parts, and ensure
that the insulation resistance levels are more than 4M.
When the insulation resistance level is lower than this value,
check repair of the transceiver is required.
