flashing red
Charging of the internal battery is activated but there is an error in
charging the battery.
Recommended user action: Check and
reattach the battery. If the problem does
not disappear, please send the battery to
Leica Geosystems Service.
Charging is only indicated via LEDs when
the instrument is turned off. When the
instrument is on, the LEDs indicate the
current power level.
Troubleshooting: If the GR25/50 is off and
the user tries to turn on the receiver but the
configured power up voltage is higher than
the current input voltage, the receiver will
not boot. The power LED will flash three
times to indicate the higher power up
voltage.
Please attached a higher voltage power
source.

Press and hold the power button until the
power LED turns green (approximately
30s). This will overwrite the configured
power up voltage.
