2. After the bump test or calibration has been completed, turn off the
instrument(s) by selecting the instrument(s), right clicking on them, and
selecting Power Off. The docking station will automatically turn off the
instrument(s) 20 seconds after a successful bump test or calibration or if there
is no activity for the time period defined by Auto Power OFF Time in the
Configuration Window.
3. While the instrument is on, the CHARGE LED will be blinking green. When the
instrument is turned off, the CHARGE LED will blink amber. The BUMP
T
and/
or CAL S LED will continue to be either green or red depending on the result
of the previous bump test or calibration. If the bump test or calibration was
cancelled, the BUMP
T
or CAL
S
LED will be solid amber.
NOTE: The SDM-2009 does not start charging the batteries until the
instrument is off. While the instrument is on, the CHARGE LED will
blink green. Once the instrument is shut off, the CHARGE LED will
begin to blink amber.
4. If the batteries are fully charged, then the CHARGE LED will turn solid green in
a few minutes.
If the batteries are drained enough for the docking station to charge them, the
CHARGE LED will continue to blink amber while charging is taking place. The
SDM-2009 will take approximately 3 hours to charge fully discharged batteries.
If the charging process encounters a fail condition, the CHARGE LED will turn
steadily red.
NOTE: If the GX-2009 is left in the SDM-2009 after bump testing or calibration,
the pump will run for 12 seconds every 2 minutes in order to keep
hydrogen generated from charging of the NiMH batteries from affecting
the CO sensor.
5. When the charge is complete, the CHARGE status LED will turn solid green.
Recharging the Batteries Without Performing Any Operations
To recharge the batteries in an instrument without performing any other operations:
1. Confirm that the AC adapter is connected to the back panel of the SDM-2009

2. Insert the instrument into the instrument cradle.
3. Press and hold the SDM-2009’s POWER button. The LEDs will turn amber.
4. When the BUMP
T
and CAL
S
LEDs turn off, release the POWER button.
5. The CHARGE LED will be blinking amber.
