BH970 Wireless Mono DECT Headset User’s Guide 21
8.2 Wireless Range
The BH970 Headset supports a maximum wireless range of up to 492 feet (150 meters). Physical obstructions and electromagnetic
interference may shorten this range.
Headset sound quality may slowly deteriorate the further the headset is away from the base, and may improve the closer the headset
is to the base. When the headset is completely out of range, a unique tone (three quick descending notes) will be played in the headset
every few seconds.
If the headset is on a call when moved out of range, the audio will be lost. However, the call will remain active at the base for
120seconds. To restore audio to the call, move the headset back in range of the base.
If the headset remains out of range of the base for more than an hour, the headset will power down to conserve battery.
8.3 Headset Density Limits
Using multiple BH970 headsets in one area may have an eect on headset performance and sound quality. The recommended limit for
the number of headsets in one area before call connections may be lost will depend on EU or US DECT. The BH970 Headset uses US DECT,
if purchased in the US, and EU DECT for the rest of the world.
