7. BTS-1000 MAIN DISPLAY SCREEN FUNCTION KEYS These are Menu selection key indicators. When these keys are displayed with boxes around them they are functional, regardless of screen type (SET-UP, RESULT or CONFIGuration) and the displayed location of the keys, the operation is as defined in the HELP screen text. Selection text follows to the right of each key. When a selection is made with the function key, a box is drawn around the selection. SLIDE 7 OF 22

8. BTS-1000 MAIN DISPLAY SCREEN TITLE The text that appears in the title location always refers to the Main Menu selection and if this is a SET-UP, RESULT, or CONFIGuration screen. SIDE NUMBER The SIDE NUMBER refers to DS1 RCV1 or DS1 RCV2. If SIDE ONE is showing, selections and test results are related to the DS1 RCV1 input. SCREEN NUMBER This number allows the user to track the selected screen’s position within the total number of SETUP or RESULT screens. SETUP screens always precede RESULT screens. Use the NEXT [NXT] and PREVious [PRV] keys to select the next or previous screen. SLIDE 8 OF 22

11. BTS-1000 MAIN DISPLAY SCREEN CIRCUIT STATUS The letters FRM indicate that the circuit is framed and operational. All other indications such as LOS, AIS, RED, YEL are indications of a circuit that is not fully operational. ALARM & ERROR STATUS When any of these DS1 circuit alarms occur (LOS, AIS, LOF, RAI) a flashing A will appear. When any of these DS1 circuit errors occur (BPV, EXZ, FE, SLIP, B8ZS, CRC-6) a flashing E will appear. SLIDE 11 OF 22

The impedance selection is indicated by the two LEDs above each key. TERM is selected when the test set terminates the DS1 circuit. The TERM LEDs are lit. BRIDGE is selected if a high impedance input is required. Both LEDs are lit. The BRIDGE mode must access a terminated cable pair for readings to be accurate. This is the POWER ON default mode. MONITOR is used for resistive monitor jack applications. The MON LED will be lit. Note: If the MONITOR jack is not resistor isolated, use the BRIDGED mode. AUXILLIARY ACCESS This location is reserved for future options. SLIDE 16 OF 22
