Public TTY Installation Testing, and Troubleshooting Guide Tuesday, February 19, 2002 typed by: The Clone found by: MSM and son4r - For use on Millennium Payphones Manufacturer: Ultratec, Inc. The Public TTY consists of: * Drawer Assembly * Interface Cable * Interface Board * Power Transformer * Shell - Installation Step 1 - REMOVE THE DRAWER 1. Use the included wrench to remove the six outside security screws from the bottom of the shell. 2. Slide the drawer assembly halfway out. 3. Disconnect the drawer assembly cable from the interface board by squeezing the tabs on the white plastic connector and pulling the connector out. - Installation Step 2 - MOUNT THE SHELL If shell is not pre-drilled, drill and countersink at least 4 mounting holes in the top of the shell. Use #10 or ¼" slotted flathead screws. Screws must be flush with the inside of the shell or they will impede the drawer's motion. Attach the shell. - Installation Step 3 - CONNECT THE TRANSFORMER CABLES Model M240FS Notes CAUTION: Be sure to put the transformer in an enclosed, sheltered location. Remove the wiring cover next to the interface board inside the shell before attempting to connect the power transformer cables. Replace the cover when all wires are connected. Adding wire to the transformer: These gauges must be used to add extra wire to the transformer secondary Add. Feet Wire Gauge 12 22 19 20 30 18 48 16 77 14 123 12 Verify wire connections are electrically sealed and meet appropriate safety standards for your area. General Connection Instructions: 1. Be sure the transformer is unplugged. Route the cable from the power transformer through the hole in the back of the shell, through the cable Tywrap, and up to the POWER terminal block on the interface board. 2. Attach the transformer wire with the red lug to the +12V position. 3. Attach the wire with the black lug to the position marked GND. 4. Install a separate ground wire by attaching one end to the telephone's ground post, routing the ground wire through the Tywrap cable and the back of the shell, and attaching the other end to the position marked _+_ 5. In a noisy environment, the TTY can mute the handset to prevent background noise from disrupting the text conversation. Handset muting shorts the handset microphone contacts during TTY conver- sation. To mute the handset, connect a blue wire and a brown wire to the J2 (HANDSET) terminals. Polarity is not important. Connect the wires to the payphone terminal that controls the handset microphone. - Installation Step 4 - CONNECT THE TELEPHONE LINE Route the telephone line through the hole in the shell and the cable Tywrap and up to the J3 (LINE) terminal block on the inter- face board. Connect the more positive lead of the pair to R(+) Connect the other lead to T(-). Tighten the Tywrap.

Slide the drawer assembly halfway into the shell. 2. Reconnect the drawer assembly cable to the interface board. The connector is keyed to plug into the socket only one way. 3. Slide the drawer assembly all the way in until the bottom front edge of the drawer assembly is aligned with the shell. Be careful not to pinch any cables between the back plate, the interface board, and the internal drawer components. Be sure that the switch wire loop is bent toward the center of the drawer. 4. Use the six security screws to attach the drawer to the shell. 5. Mount the handset cradle close enough for easy access by the user. Be sure the handset card does not block typing. 6. Install one of the enclosed user instruction labels on the front of the drawer and the other one at eye level on the enclosure. - Installation Step 6 - TESTING AND TROUBLESHOOTING 1. Plug the power transformer into a standard ground 3- position 110 VAC electrical outlet. Caution: The drawer will open automatically when you plug in the transformer. 2. Place a regular payphone call. The Public TTY should not interfere with use of the phone. 3. Put the payphone handset in the handset cradle and press *8* twice within 7 seconds. The TTY drawer should open fully and you should see a statistics menu prompt on the display. Hang up the handset. The TTY drawer should automatically close within a few seconds. If the drawer fails to close: unplug the transformer and reverse the Tip and Ring connection. The voltage potential between Tip and Ring must be greater than 30 VDC. If the drawer does not close when you plug in the transformer again, call Ultratec at: 1-800-482-2424. 4. Repeat Step 3, except that when the TTY drawer begins to close, pick up the handset again and quickly press the spacebar. The TTY drawer should open again. Hang up the handset and allow the drawer to close. 5. Important safety check: Repeat Step 3 again, except that as the TTY drawer begins to close, place an object such as a screwdriver handle between the TTY drawer and the shell. The TTY drawer should reopen when it hits the obstruction. If the TTY drawer fails to reopen, it must be returned to Ultratec. 6. Pick up the payphone handset and press the * key on the payphone 3 times. Listen to the handset. A recorded voice should repeat the phrase, "TTY call, please use text tele- phone," until the drawer opens or you press any key on the payphone keypad. Note: Because some payphones may not pass DTMF until you make a connection, you may need to make an actual call to test the announcer. You can call any voice number. 7. Call another TTY and use the keyboard to type a message. If you do not have a local TTY number, call Ultratec at: 1-800-482-2424 and ask for a Public TTY test. If you are not familiar with TTY calling, call customer service at Ultratec and ask for assistance. - END OF FILE.
