3While still holding ", press O.

The handset beeps twice, and the display shows the handset settings, indicating you are in Local Mode. (While in Local Mode, the MDW telephone can still receive notification of incoming calls.)

4Press “W” ( 9) to enter Wireless Test Mode..

Note: In a multiple TransTalk installation, put all of the handests in Wireless Test Mode at the same time. This allows you to observe if all handsets are working properly together.

WIRELESS TEST appears on the top line of the handset display. The handset beeps twice and vibrates, then you hear a simulated dial tone. This dial tone continues until you exit Wireless Test Mode. While in this mode, the MDW telephone cannot make or receive calls.

For all sets, do the following.

5Press 1.

The display should show a 9 or 10 for signal strength (an occasional 8 is acceptable).

6Press 2.

The display should show a 9 or 10 for voice quality (an occasional 8 is acceptable).

Note: If you are seeing numbers lower than 8-10 for either signal strength or voice quality while performing the Close Up Test, please refer to either the "Installing a Single Carrier" section, or "Installing Multiple Carriers" section in this manual. This will ensure that your installation meets all installation and environmental requirements.

Edge of Range Test

1Periodically check the signal strength and voice quality as you walk away from the radio module. Each time you press 1 or 2, you get a new reading.

When you see a signal strength of 3 at a power level of 8, you are at the “edge of range” for the MDW telephone. The distance will vary depending on the environment, building structure, and other factors. The range in an average office building is 500–700 feet (152.5–213.5 m). If, however, dense walls intervene, the distance could be less.

2With a signal strength of 3, press 2 to check the voice quality. When the voice quality is 7 or 8, the voice connection should be satisfactory. This is the edge of your usable range.

The following diagram illustrates this Performance/Range test.
