• If you attempt to test while the wrist strap LED is blinking and without having
the wrist strap connected to the Shoes and Wrist Strap Tester 747, “Err.2”
appears on the LCD. In this case, connect the wrist strap cable to the front
panel connector and test again.
• Conducting a wrist strap test followed immediately by a shoe test allows the
shoe test to be performed while the wrist strap remains connected to the front
panel when testing one shoe only.
