1900E may not be powered (dead or missing battery and no power from the AC/DC
adapter). If all of these items have been checked and you still have no tones coming
from the telephone you should return it to your service provider for service and/or
assistance.
SAU-1900E OPERATION
LED Indicators
Your SAU-1900E has three LED's (light emitting diodes) to let you know the
status of your SAU-1900E unit. They are:
SIGNAL: This LED is an indicator of the received signal strength from a cellular base
station that communicates with your SAU-1900E. It has three possible states:
1. When the SIGNAL LED is constantly lit your SAU-1900E and the cellular base
station should have no difficulties communicating with each other.
2. When the SIGNAL LED is blinking, this means that communication between the
SAU-1900E and the cellular base station is working, but marginal. This means that
you should still be able to place and receive calls, but could possibly experience
occasional dropouts in your conversation and even occasional dropped calls. (If you
are using the included antenna, and experience this condition frequently, you may
want to talk to your service provider about getting an externally mounted antenna to
improve your reception.)
3. When the SIGNAL LED is not lit, this means that your SAU-1900E is not
communicating with the cellular base station. This means that you will not be able to
place a call or receive a call on your SAU-1900E.
AC/BATTERY: This LED is an indicator of the power source being presently used by the
SAU-1900E. It has three possible states:
1. A constantly lit AC/BATTERY LED indicates that AC power is being used to power
the SAU-1900E.
2. When the AC/BATTERY LED is blinking, this indicates that no AC power is present,
and the internal battery is powering the SAU-1900E.
3. When the AC/BATTERY LED is off, this indicates that the SAU-1900E is not
powered (i.e. no AC power is provided, and either the internal battery has been
completely discharged or is not installed). In this condition, the SAU-1900E will not
be able to provide any telephone service.
