Note:
If you are seeing numbers lower than 8-10 for either signal strength or

Edge of Range Test
1
Periodically 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.
2
With 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.
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.
