SAFETY CHECK-OUT
(US Model only)
1.
Check the area of your repair for unsoldered or poorly-soldered
connections. Check the entire board surface for solder splashes
and bridges.
2.
Check the interboard wiring to ensure that no wires are "pinched"
or contact high-wattage resistors.
7.
Check the condition of the monopole antenna (if any).
Make sure the end is not broken off, and has the plastic cap on it.
Point out the danger of impalement on a broken antenna to the
customer, and recommend the antenna's replacement.
9.
Check the antenna terminals, metal trim, "metallized" knobs,
screws, and all other exposed metal parts for AC leakage. Check
leakage as described below.
