• Good – provides full-duplex operation with the Internal or External Microphone. This is ideal
for a small office with high echo.
• Normal – provides full-duplex operation with the Internal or External Microphone. This works
well with an open office area, such as an office cubicle.
Table 11-11 shows the switch positions for the three different settings.
Table 11-11 DKT2020-FDSP DIP Switch Settings
Note The first four DIP switches are used to select the country, same as all other DK2000-series
telephones. The default DIP switch settings (1~4) are preset to On for the USA and Canada.
If you need to make adjustments for other countries, see Table 11-10 on page 11-52.
³ To use the External Microphone
1. Plug in the RFDM External Microphone to the bottom of the phone (see Figures 11-37 and
11-38).
2. Turn the microphone On by opening it (see Figure 11-39).
Note The High/Low switch works independently from the telephone’s speakerphone. This setting
must be on High for proper operation.
Important!
● The microphone has a narrow voice pick-up range so the front of the microphone should
always point toward the person speaking (see Figure 11-40).
● Be sure to place the microphone at least one foot from the telephone speaker and do not point
the microphone toward the telephone speaker grille.
● To use the external microphone in a conference room setting, place the microphone away from
all parties to eliminate some of the directional effect. Parties may have to speak up to be
heard.
● The RFDM External Microphone is not compatible with the HHEU or BHEU.
CAUTION! Avoid pulling the microphone cord excessively.
