 IP4100-BASE Single-Cell vs. Multi-Cell Systems:

Use a single-cell layout if

  •     A customer’s needs can be met by a single base station.
  •     A customer has several locations that can each be served by a single base station.
  •     Users don’t need to roam beyond the base station’s coverage area or between locations.

Use a multi-cell layout if

  •     The customer requires more handsets or extensions than a single base station can provide.
  •     Users need the ability to roam beyond a single base station’s coverage area or between locations.

IP4100-DECT Troubleshooting Suggestions

Handset – If you have any trouble with your handset, try these simple steps first.

If a handset can’t make or receive calls, try moving the handset closer to the base.

If a handset can make calls, but it won’t ring, try making sure the ringer is turned on.

If a handset is not working, try charging the battery for 15-20 hours and checking the battery connection.

If a handset says Searching, try moving the handset closer to the base.

Weak or Hard to Hear Audio

If a caller’s voice sounds weak or soft, the signal might be blocked by large metal objects or walls; you might also be too far from the base, or the handset’s battery may be weak.

  •     Try moving around while you’re on a call or moving closer to the base to see if the sound gets louder.
  •     Make sure the handset’s battery is fully charged.
  •     Try adjusting the earpiece volume.

Noise or Static on the Line

Interference is the most common cause of noise or static on a cordless handset. Here are some common sources of interference:

  •     electrical appliances, especially microwave ovens
  •     computer equipment and DSL modems
  •     radio-based wireless devices, such as room monitors, wireless controllers, or wireless headsets or speakers
  •     florescent light fixtures (especially if they give off a buzzing noise)
  •     other services that use your handset line, like alarm systems, intercom systems, or broadband Internet service

If the static is on 1 handset or in 1 location:

  •     Check nearby for one of the common interference sources.
  •     Try moving the handset away from a suspected source or try moving the suspected source so it’s not between the handset and the base.
  •     There is always more noise at the edges of the base’s range. If the handset displays Searching, try moving closer to the base.

If the static is on all handsets or in all locations:

  •     Check near the base for the source of interference.
  •     Try moving the base away from a suspected source or turn off the source if possible.
