Telephone Line Testing

Pressing C for touchtone dialing or D for rotary dialing, followed by [ENTER/STORE] causes seizure of the

Primary phone line. After a delay of three seconds, the 411UDAC goes off-hook to acquire a dial tone.

The Programmer keypad may be used as a telephone touchpad for number dialing. Once the first digit is pressed, the

display will move the C or D character one position to the left, while placing the digit to be dialed on the farthest right

display position. Continue to press the phone numbers to be dialed. Successive depressions of the [ENTER/

STORE] key hangs up and picks up the phone (places the phone on or off the hook).

The secondary phone line may be tested by pressing the E key for touchtone dialing or the F key for rotary dialing

and then following the same procedure used for the primary phone line. A handset may be temporarily connected

across transformer T1 of the 411UDAC as indicated in Figure 3-3. The handset, when connected across T1, may be

used only as an amplifier/speaker or telephone with the keypad used for number dialing.
