Installing Batteries
You need six AA batteries to power your detector. Use only fresh batteries
of the required size and recommended type. Do not mix old and new
batteries, different types of batteries (standard, alkaline, of rechargeable), or
rechargeable batteries of different capacities.
1. If the detector is on, turn VOLUME (on the control housing) to OFF (The
control clicks).
2. Press on the battery compartment cover and slide the cover off.
3. Insert the batteries into the compartment as indicated by the polarity
symbols (+ and -).
4. Replace the cover.
Important: Always remove old or weak batteries and dispose properly.
Batteries can leak chemicals that can destroy electronic parts. If you do not
plan to use the detector for a week or more, remove the batteries.
Testing the Batteries
If the detector does not turn on, has weak volume, will not tune properly, or
has erratic operation, or drifts, test the battery power. Rotate VOLUME away
from OFF and set OPERATE to BATT TEST. If the pointer on the viewmeter is
between 3 and 6 (green area), the batteries have enough power to operate the
detector. If the pointer is not in the green area, replace the batteries.
Using Earphones
You can connect a pair of stereo earphones to the detector. Using earphones
also saves battery power and makes it easier to identify subtle changes in the
sounds you hear, for better detection results. To connect earphones to the
detector, insert the earphones' 1/8-inch plug into the EAR jack on the side of
the control housing. The detector's internal speaker disconnects when you
connect earphones.
Attention: Set the volume to the lowest setting before you begin listening
and adjust the volume to a comfortable level. Do not listen at extremely
high volume levels. Extended high volume listening can lead to permanent
hearing loss. Once you set the volume, do not increase it. Over time, your
ears adapt to the volume level, so a volume level that does not cause
discomfort might still damage your hearing. Do not wear earphones while
operating your detector near high-traffic areas.
