cord with the square plug.
2. Place the black (–) probe on each of the pins, one at a time, on the plug on the other end of the cord.
3. The multimeter should indicate continuity on only one pin. If any other reading is obtained, the cord must
be replaced.
4. Repeat the procedure three more times, each time with the red (+) probe inserted into a different terminal
on the end of the cord with the square plug.
TEST PROCEDURE 2 – HANDSET CORD ADAPTOR
See General Warning, Section 10, Page 10-1.
The procedure for testing the handset cord adaptor is similar to the cord test.

adapter with the square plug.
2. Place the black (–) probe on each of the pins, one at a time, on the other plug of the adaptor.
3. The multimeter should indicate continuity on only one pin. If any other reading is obtained, the adaptor
must be replaced.
4. Repeat the procedure three more times, each time with the red (+) probe inserted into a different terminal
