GSR2700 IS Operations Manual 45
Basic Operations Chapter 5
5.5 Insufficient Power
If both the internal batteries or the external power input voltage
are below minimum operating parameters (in other words, if the
GSR2700 IS experiences drained batteries or power failure), the
receiver will turn off and become inactive. If this happens, you
will not be able to turn the receiver back on until sufficient power
is restored.
In the event of a power failure, the GSR2700 IS power output is
disabled on both COM ports and the receiver will not resume
operations even if the power button is pressed.
To return to normal operation, charge the internal batteries or
connect a valid external power input to the receiver. When
sufficient power is restored, the COM ports will provide power
according to what the POWERUP configuration specifies and the
system will turn on if the power button is pressed. If there is no
POWERUP configuration, the COM ports will provide power as
they did before the power failure.
NOTE The GSR2700 IS limits data loss from storage in the internal
memory to a maximum of 10 seconds in the case of power
supply failure.
CAUTION
The GSR2700 IS may also become inactive
if the external power input is greater than
the power specified. See Section 1.7,
Finding More Information , page 8 for more
information.
