Checking the Power Setting and Fuses
The detector arrives with the voltage and fuses preset for your location. To verify the power
setting, look through the cutout window on the power entry module located at the lower right
of the back panel of the detector (see
).

To check the fuses and change the voltage setting
1. Place the tip of a narrow-blade screwdriver in the small slot to the left of the fuse holder in
the power entry module and push to the right. The fuse holder pops out.
2. Pull the fuse holder out of the power entry module.
3. Verify that the fuse holder contains the appropriate size fuses: T3.15 A for 100/115 V, or
T1.6 A for 230 V.
4. If necessary, slide out the voltage selection PC board and reinstall it so that the desired
voltage label is upright and readable. This voltage must agree with the incoming line
voltage.
5. Slide the fuse holder back into the power entry module until it snaps in.

the voltage is properly set for your location. Never connect the detector to or operate the
detector with an electrical line source with power drops or fluctuations greater than 10%
above or below the nominal rated line voltage.
