Phone Problems
Cannot Sign in on Local Phone
When * is pressed on the local phone within 5 seconds (see 5 for
adjustment of this time) of lifting the handset, there should be a relay
click on the panel. Subsequent keys should have beep tones as
acknowledgment that the system has detected the key presses.
1 If no relay click is heard, it could mean that the Keypad is being used.
Press F on the Keypads to end the Keypad operation and try again
2 Use a telephone which you know does work. The customers telephone
may not be compliant with telecom requirements even though it may
seem to work. If the relay clicks when the * key is pressed, but the
phone goes dead, check that the TEL IN and OUT connections have not
been interchanged.
3 Replace the U4 on the system with one which has been programmed
with default settings. If Locations relating to DTMF detection have
been changed inadvertently, it may cause this problem. If the default
U4 works, reprogram the U4 according to the customers settings using
the Keypad or CS-Xpress.
4 We have found that in rare occasions, certain telephones may not be
able to sign in locally, because they require a higher voltage to
operate than other phones. These are normally not type-approved
models. In such cases, another model of telephone on the premises
may be able to work.
5 Phones which don’t work well with Comfort:
Some of the following phones are known to have problems with
accessing Comfort due to their delayed output of the *star key tone:
Phillips Xalio DECT, BT Response 100, 200, 300, BT DECTFax, BT
Diverse 300 Answering Machine/Phone, BT Diverse 350 Caller display,
BT Siemens Diverse 2010. (DECT). There is now a new location which
allows you to set the ‘listening window’ time in seconds which Comfort
can accept a star key. This is set in location 1849 (Def: 5 seconds) and
should only be adjusted only if it is is neccessary with some DECT
phones, otherwise accessing BT Star services could be made difficult.
"Phone Trouble"
If the voice says "Phone Trouble" when the handset is lifted, it means
that the phone line is cut or not working or a phone is being used on
the incoming line to Comfort. Check the incoming telephone line
connection. Comfort detects low voltage on the telephone line and
supplies its own power to the local telephone so that it can still be used
to operate the system. The speaker produces a beeping sound for 10
seconds to indicate the trouble condition after the line has been down
for approx 60 seconds, and the green led on the PCB and keypads
flash. The condition is cleared when the line is restored and the user
signs in with their code to acknowledge. The time which Comfort allows
a Line Cut to be present is now adjustable up to 255 seconds using
Location 1684. This can be used when it is suspected that the
Telephone company provide an ‘intermittent’ service. The speaker
