Problem Cause/solution
Noise is heard, sound cuts
in and out.
R You are using the handset or base unit in an area with high
electrical interference. Re-position the base unit and use the
handset away from sources of interference.
R Move closer to the base unit.
R If you use a DSL/ADSL service, we recommend connecting a
DSL/ADSL filter between the base unit and the telephone line
jack. Contact your DSL/ADSL provider for details.
R The wireless network is congested. When using a smartphone
to talk on landline calls (page 40), sound may cut out if large
amounts of data are transmitted over the wireless network,
such as when streaming video, downloading or uploading
large files, etc.
R The base unit’s Wi-Fi repeater mode feature is turned on and
the base unit is too close to your wireless router. Turn Wi-Fi
repeater mode off (page 41), or place the base unit and your
wireless router further from each other.
R The base unit’s Wi-Fi repeater mode feature is turned on and
you are also using a Wi-Fi range extender. Do not use Wi-Fi
repeater mode if you already have a Wi-Fi range extender.
Sound quality seems to be
getting worse.
R You have registered a handset that is not recommended
(page 4). The clearest sound quality is only possible by
registering the recommended handset.
The handset does not ring. R The ringer volume is turned off. Adjust ringer volume (page 15,
23).
R Night mode is turned on. Turn it off (page 28).
I cannot make a call. R The dialling mode may be set incorrectly. Change the setting
(page 14).
R You dialled a call restricted number (page 31).
R The key lock feature is turned on. Turn it off (page 17).
Caller ID
Problem Cause/solution
Caller information is not
displayed.
R You must subscribe to a Caller ID service. Contact your
service provider/telephone company for details.
R If your unit is connected to any additional telephone
equipment, remove and plug the unit directly into the wall jack.
R If you use a DSL/ADSL service, we recommend connecting a
DSL/ADSL filter between the base unit and the telephone line
jack. Contact your DSL/ADSL provider for details.
R Other telephone equipment may be interfering with this unit.
Disconnect the other equipment and try again.
Caller information is slow
to display.
R Depending on your service provider/telephone company, the
unit may display the caller’s information at the 2nd ring or later.
Set the first ring to “Off” (page 23).
