Start-Up Process
Installing the Batteries
The Monitor uses two (2) AAA alkaline batteries. When changing out used-up batteries, make sure to use
new batteries. The Monitor will alert you when a battery change is needed. Batteries should be installed
right after unpacking the Guardian RT.
NOTE - Use only disposable AAA alkaline batteries in the Monitor. Do not use rechargeable batteries
or other battery types. These batteries can damage the Monitor or affect Monitor
operation.
If batteries are not changed within 10 minutes of taking out a used-up set, an alarm will be
triggered, and the Sensor will have to be replaced. (See Chapter 4: Troubleshooting and
Alarms.) Be sure to have a new set of batteries ready when replacing the old set.
In order to properly save and keep stored Monitor information, always turn the Monitor off
before changing batteries.
4. Find the battery compartment on the back side of the Monitor.
5. With the screwdriver provided, loosen the screw while holding the Monitor’s battery compartment
lid. Do not try to fully remove the screw; it is meant to stay attached to the lid.
6. Take off the battery compartment lid.
7. If you are changing batteries, first pull on the ribbon to loosen. Next, take out the old batteries with
your fingers.
8. Place the battery strap around the new batteries. Refer to the diagram on the inside of the battery
compartment lid.
CAUTION: If the batteries are put in with the positive and negative
terminals switched, they will become very warm, and the
Monitor will not work. Carefully, place the batteries in the
Monitor correctly.
