TROUBLESHOOTING GUIDE

SYMPTOM
1. Ensure batteries are installed in the correct orientation.
No power
2. Replace all old batteries with all new batteries.
1. Ensure your searchcoil is securely connected and the coil
cable is snugly wound around the stem.
2. If using the detector indoors, be aware that excessive
amounts of electrical interference exists, plus excessive

movement 3. Determine if you are close to other metal detectors or other
metal structures such as electrical power lines, wire fences,
benches, etc.
4. Adjust frequency
5. Reduce your sensitivity setting.
Intermittent signals typically mean you've found a deeply
buried target or one that is positioned at a difficult angle for
your detector to read. Scan from different directions to help
define the signal. In the case of multiple targets switch to the

detects all metal targets to ensure desired targets are present.
If your Target ID Cursor bounces erratically, chances are
you've found a trash target. However, a Target ID Cursor may
bounce if a good target (such as a coin) is not parallel to the
searchcoil (e.g. on edge). It may also bounce if there is one
or multiple "junk" targets laying next to the good target. Scan

from different directions until your Target ID Cursor becomes

NOTE: Large, flat pieces of iron—depending on their
orientation in the ground—can read as a good target or can
cause erratic Target ID Cursor movement. Use Iron Audio to
help identify iron targets.

BATTERY REPLACEMENT

Battery Level
Indicator
Four bars indicate fully charged batteries. Replace batteries
when there is only 1 bar remaining. The detector will maintain
full performance until the batteries need to be replaced.
NiMH rechargeable batteries may be used, but may have
a shorter life per charge. You can expect 20 to 40 hours of
operation depending on battery type and quality.
Replace the batteries by sliding the cover off the control
housing. Remove batteries when the ACE 400i will be stored
for longer than 30 days.
Note: 1.5V/cell Lithium batteries can also be used, but the
use of 3.7V/cell Lithium batteries will damage the detector.
