9. Remove the two screws that secure the sensor to the amplifier,
then remove the sensor from the amplifier. Retain the amplifier for
use with the replacement sensor.
10. Install the replacement sensor in reverse order.
NOTE: Allow up to 4 hours after you replace a non-standard toxic
gas sensor, or if charged batteries have not been installed for
an extended period, for the channel to show a normal
response, then calibrate the sensor.
