New Zealand Telecom Warning Notice
Use of pulse dialing, when this equipment is connected to the same line
as other equipment, may give rise to ‘bell tinkle’ or noise and may also
cause a false answer condition. Should such problems occur, the user
should NOT contact the Telecom Faults Service.
The preferred method of dialing is to use DTMF tones, as this is faster
than pulse (decadic) dialing and is readily available on almost all New
Zealand telephone exchanges.
Warning Notice: No '111' or other calls can be made from this device
during a mains power failure.
Use of Supplied Power Transformer
The power transformer supplied with the modem is the only one that
should be used. Use of any other transformer could cause damage to
the modem.
