will light briefly so you know the detector is working properly, and the batteries are good. Turn unit "Off"
when not being used.
Whenever the low battery dial arrow points to "R" (Replace), replace the batteries.
Many metal detector problems are caused by weak, dead, or improperly connected batteries. If the detector
does not turn on, has weak volume, will not tune properly, has erratic operation, or drifts, replace the
batteries.
You can extend battery life by using headphones. A headphone jack is provided and can be used with any
1/4-inch stereo-type headset.
Remove the batteries if you do not plan to use the detector for a week or more.
RESETTING THE DETECTOR
The detector might "lock up" and sound a continuous tone if you have low battery voltage or are testing the
detector with the searchcoil near a large metal object.
Check and replace the batteries if necessary.
Move to a different testing location.
Reset the detector by turning it off and on repetitively.
SENTRON CO-RELATOR ANTENNA
This unique feature of the Time Ranger monitors outside interference levels, allowing the detector circuit to
make automatic adjustments. It also performs an important function related to the Smart Trac and Ground
Monitoring Systems. When in operation, the antenna should be extended. When stored, or not in use, the
antenna should be retracted. The Red LED Light at the rear of the Sentron will alert you whenever the
Ground Monitor goes negative.
Using headphones (not supplied) with your metal detector makes it easier to identify subtle changes in the
threshold levels for better detection results, and also reduces drain on the batteries.
The Time Ranger Metal Detector has a stereo headphone jack.
To connect headphones, insert the headphones'
1/4-inch plug into the headphone jack on the underside of the control panel (see illustration).Listening Safely
To protect your hearing, follow these guidelines when you use headphones. Purchase stereo headphones that
have right and left side volume controls.
Set the headphone volume to the lowest setting before you begin listening. After you begin listening, adjust
each volume control to a comfortable level.
Do not listen at high volume levels. Extended high-volume listening can lead to permanent hearing loss.
Once you set the volume controls, do not increase it. Over time, your ears adapt to the volume level, so a
volume level that does not cause noticeable discomfort might still damage your hearing.
