9.1.4 ON/OFF button flashing
The ON/OFF button emits a flashing blink code to communicate a problem when the software is unavailable.
2 blinks in quick
succession followed by
a solid long pause.
Indicates problem with main power supply. Could
indicate power has been interrupted. Flashing
ceases when reserve power is depleted if it is not
replenished.
Check the security of the power cord and its
connection. If there is no facility power outage,
problem could be with power unit and a replacement
is necessary. Call service.
3 blinks in quick
succession followed by
a solid long pause
Indicates the system has detected a problem with
the main power supply and has attempted to
restore normal power supply operation without
success.
There is likely a problem with the main power supply
and a replacement is necessary. Call service.
Operation may be temporarily restored with the
following procedure: Unplug the power cord from the
instrument until the power button stops blinking,
then reconnect the power cord. If the instrument
powers up normally, continue to use while waiting
for the replacement power supply.
6 blinks in quick
succession
It is too hot inside the instrument. The device is
rated for an environment up to 35 °C (95 °F).
Instrument shuts down its power source when it
is too hot.
Check ambient temperature in the environment
around the instrument. If the temperature does not
exceed the rated limit, call service.
9.1.5 Quick reference troubleshooting
Probe is not emitting laser
Check whether the probe is connected properly. Confirm that laser key is turned ON
and indicator light is lit. Inspect whether the shutter switch is in the ON position.
Examine whether the remote unlock connector is present on specific channel.

responding
Reboot device by holding the ON/OFF button on the front of the device for 12 seconds
until it powers down. Release power button. Depress power button momentarily to
power the device back up.
