TT-200 (BS-100) 2/12/01 4:00 PM Page 2 INTRODUCTION The TT-200 is designed for the installers, repair technicians, and other authorized personnel for line testing and temporary communications. The test set employs the latest in integrated circuit design to provide DTMF (Touch Tone) and dial pulse output. Different from other test sets, it contains a mega ohm (MΩ) meter for testing insulation resistance and telephone capacity.

TT-200 (BS-100) 2/12/01 4:00 PM Page 5 OPERATION INSTRUCTIONS PLACING A NORMAL CALL A calling signal is sent to the subscriber's telephone causing it to ring. 1. Set to data safe mode by pressing the MON (9) switch. 2. Connect the alligator clips to L1 and L2 of subscriber side. 3. Listen for a clear line (no data). 4. Release the data safe mode by pressing MON switch again. A dial tone should be heard. 5. Select the type of dial signaling required, touch-tone or dial pulse, with the TONE/PULSE switch.
TT-200 (BS-100) 2/12/01 4:00 PM Page 6 OPERATION INSTRUCTIONS (CON’T) REDIAL (RD) Will redial the last number entered. 1. Press the FS button for a new dial tone. 2. Press the RD button to redial the last number entered. Up to 32 digits can be redialed. MUTE (MU) When pressed, the transmitter is muted and the side tone is eliminated. 1. Press and hold the MU to mute, release to talk. FLASH (FS) The tester produces a line break (hook flash). It is typically used for register recall or redialing. 1.
TT-200 (BS-100) 2/12/01 4:00 PM Page 7 OPERATION INSTRUCTIONS (CON’T) INSULATION RESISTANCE & CAPACITY MEASUREMENT 1. Connect the alligator clips to L1 and L2 of subscriber side. 2. Push the METER CALL (10) button. 3. The insulation resistance will be displayed on the 'Mega Ohm meter, when the METER CALL button is pressed. Generally, there are two conditions: Normal condition (good insulation between L1 and L2) The meter scale goes to 0.2Ω generally and then back.
