telephones on the same line are also hung up.
3. The TT-400 meter should read in the LOOP OK area. If not, unplug each telephone one at a time. If
unplugging a telephone causes the TT-400 meter to read in the LOOP OK area, that telephone is probably
defective.
4. If the TT-400 meter still does not read in the LOOP OK area with no telephone connected, repeat steps 1
through 3 several times at 20 minute intervals to see if the problem will go away.
5. If the problem does not go away, the telephone line may be bad. Before contacting the telephone company,
carefully recheck all of the newly installed wiring and correct if necessary.
6. If you leave your telephone connected to the TT-400 with the switch set to LOOP, the telephone will effectively
be off-hook and anyone trying to call you will get a busy signal.
TELEPHONE CORD TEST
If the line voltage check out OK but the telephone still does not work, the telephone line cord may be bad. This
test checks the condition of the line cord. It may be done only if the telephone line cord can be unplugged at
both ends. Before starting the test, check that the line cord is fully inserted into the jack at both ends. If the
telephone still does not work, proceed as follows:
1. Disconnect the telephone cord and connect one end of the cord to the wall jack and the other end to the
INPUT jack of the TT-400.
2. Set the TT-400 switch to the LINE/RING position and plug the TT-400 cord cord into the telephone. Be sure
all phones are hung up.
3. Move the telephone cord about, squeeze and release it, and tug gently at both ends.
4. If the meter reads near zero or if it jumps around while the telephone cord is being moved, the cord is bad.
