INSTALLING BATTERIES
The T330BA requires six AA-size batteries
Do not mix old and new batteries, different types of batteries (standard, alkaline,
or 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 in the direction
of the arrow.
3. Insert the batteries into the compartment as indicated by the polarity symbols
(+ and –) marked inside the compartment.
4. Replace the cover.
•
Always remove old or discharged batteries; 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.
•
Dispose of old batteries promptly and properly.
You can extend battery life by using headphones, which require less power than
the built-in speakers. See “Using headphones” below.
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 the VOLUME control clockwise, away from OFF and set
OPERATE/BATT TEST to BATT TEST.
If the pointer on the meter 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 HEADPHONES
You can connect a pair of stereo headphones (not supplied) to the detector so
you can listen to it privately. Using headphones also saves battery power and
makes it easier to identify subtle changes in the sounds you hear, for better
detection results.
To connect headphones to the detector, insert the 3.5 mm jack from the
headphones into the socket labelled EAR on the side of the control housing.
The internal speaker is disconnected when you connect earphones.
LISTENING SAFELY
To protect our hearing, follow these guidelines when you use earphones.
•
Set the volume to the lowest setting before you begin listening. After you
begin listening, 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.
