Call Center & Phone Products - PCTI

Could I use the AWS-100 in conjunction with the PCTI? - Yes.

When I turn on the headset there is a piercing sound of feedback for several seconds even though the microphone is muted. Why? - This should not occur if the unit is connected directly to your computer. The QW-1000 is not compatible with the PCTI, and the problem reported may occur with that set-up. If the unit is connected to the computer and this symptom occurs, the unit needs to be returned for calibration. A unit may go out of calibration if it is dropped onto a hard surface. Feedback from the noise canceling mic and the headset speaker cause this problem.

What is the difference between the PCTI and the PCTI II? - The PCTI has a switch to select audio from the PC, the telephone, or BOTH. The PCTI also can select either an electret or carbon telephone mic input. The current standard telephone mic is electret. Carbon telephone mics were used on rotary dial phones. The PCTI 2 can only select PC OR telephone audio.

I get a hum when "Phone" or "Both" (PCTI only) is selected, but not when "PC" is selected, is there anything I can do? - Insure the PC is grounded. Do not have the PCTI too close to any devices with AC transformers such as: Desk Radios, AC adapters for Laptops or powered speakers, fluorescent desk lamps etc. Route AC power cords away from the PCTI box itself. Power cords next to any PCTI cables are OK.

Is the PCTI compatible with digital phone systems? - The PCTI will operate on an analog or digital phone system if the phone has a conventional handset. The PCTI connects to the handset cable, not to the phone line.

Will the PCTI work with a phone that has a keypad in the handset? - No.

What are the requirements for using the PCTI? - Telephone with compatible handset (no keypad in it), PC with microphone input jack and speaker or line output jack, AC output for included Power Adapter.

Why can't you tell me if the PCTI will work with my phone? - There are thousands of phones on the market. We are compatible with a large number of phones, but not all.

What headsets will work with the PCTI? - The PCTI works with any analog ANC or NC headset.

The QW1000 is NOT compatible with the PCTI.

The NC-7100 is a USB microphone and is not compatible with the PCTI.

I hear a radio station through the PCTI, what can I do? - Wiring in your building is picking up the radio signal. Usually AM radio stations can be heard. There is no problem with the PCTI. If the radio station transmitting antenna is close the problem will be worse.

The grounding of the computer should be checked. Most desktop computers have 3-prong AC cords. They need to be plugged into a 3-prong grounded outlet. The 3 -prong to 2-prong adapters, if used, must have the ground wire connected. The computer, PCTI and Phone (if it connects to AC power) should be plugged into the same outlet.

Some cases can be solved by adding an RF filter to the phone line. The filters are available at Radio Shack (P/N 43-150 for approximately $19.95). This filter will be most effective if the AM frequency is at the high end of the AM band. If the frequency is mid to low end of the band a filter that covers that frequency is needed (try a radio/TV repair store).

If after trying the above they still have a problem, the only real solution is to use shielded phone lines (probably not practical to change).

Will the PCTI drive digital speakers? - No. The PCTI drives analog speakers only.
