GSR2700 ISX Operations Manual 51
Powering the GSR2700 ISX
Chapter 6
6.5 Insufficient Power
If both of the internal batteries or the external power input
voltage are below minimum operating parameters (in other
words, if the GSR2700 ISX 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
you restore sufficient power.
In the event of a power failure, the power output is de-activated
on both COM ports and the receiver will not power on 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 (for
details about the POWERUP configuration, see Section 7.2.2.1,
Defining receiver behavior with POWERUP , page 54). If a
POWERUP configuration isn’t set on the receiver, the COM ports
will provide power as they did before the power failure.
Power failure while logging data
In case of a power failure while logging data, the receiver will
save the data to internal memory and close the file. If this occurs,
up to 10 seconds of data may be lost from the file.
CAUTION
The GSR2700 ISX may also become
inactive if the external power input is greater
than the power specified as acceptable for
the receiver. For more information, see
Section 1.5,
Usage Cautions , page 6.
