* Although the formal technical specifications for all Digital Mobility Handsets are 100 ft/300 M (line of sight to basestation), in certain environments the 7420 Handset has
enjoyed a greater range (up to 15 percent further) due to different feature sets. As such, minor modifications to existing 7420-based configurations may be required when
introducing the 7430/7440 handsets. Nortel recommends that all deployments include sufficient overlap to accommodate a mixed handset environment.
** Languages supported include English, German, French, Italian, Spanish, Dutch, Portuguese, Turkish, Danish, Swedish and Norwegian.
