Operating tips
Use with Telecare terminals or other automatic dial equipment.
When using equipment that dials into call monitoring centres with signalling equipment, mute the
DTMF tones while the call is being established (CFG28=1 / *828*1#). This will prevent the dialling
terminal from being confused by the dialling tones made by the T400LR.
Phone used in an unattended location or for public use
When providing a courtesy phone or similar, we recommend restricting the call duration to avoid an
excessive call cost or blocked destination if the caller does not hang up the phone.
See CFG6=n / *86*[limit]#.
Using a phone located in a location with a weak mobile signal
Locate the terminal in a location where there is an acceptable level of mobile signal then connect a
longer extension cable to the telephone. For example, the T400 could be in an upper floor near a
window and the phone could be in a ground floor lobby. Using an external antenna connected by a
long cable is less desirable as some of the signal is lost in the cable, whereas a long phone extension
cable will not impair the performance. Where an external antenna is appropriate, we recommend the
2J2024GP wall mount antenna which is available from Burnside suppliers.
Working with SIMs and the pros & cons of 3G
There is a misconception that a SIM requires a terminal that supports a 3G or 4G network. In fact,
most SIMs will work in 2G for voice. The primary advantage of 3G and 4G is high speed data, but the
signal strength is weaker (1/8
th
) so the coverage can be sparse apart from urban areas. For a voice
application, 2G works well and in many cases is much more suitable.
