polarity. Then put the battery into the compartment.
4. Replace the cover.
Cautions:
• Use only fresh batteries of the required size and recommended
type.
• Always remove old or weak batteries; batteries can leak
chemicals that can destroy electronic parts.
• If you do not plan to use the detector for a long time, remove
the batteries.
• Dispose of old batteries promptly and properly.
You can extend battery life by using earphones, which require less
power than the built-in speakers.
USING EARPHONES
You can connect a pair of headphones (not supplied) to the detector so
you can listen privately. 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 earphone’s 3.5mm plug into the EAR
jack on the control panel.
Note: The detector’s internal speaker
disconnects when you connect earphones.
