Battery Installation

The Metal Detector requires the use of six AA bateries. Do not mix old and new batteries and do not mix different types of batteries.

1. If the Metal Detector is on, turn the volume on the control housing to OFF (see Figure 4).

2. Press on the battery compartment cover and slide the cover

Figure 4

off in the direction of the arrow (see Figure 5).

3. Insert the batteries into the compartment as indicated by the polarity symbols (+ and -) which are marked inside the compartment (see Figure 6) Replace the cover.

Remember to remove batteries if you do not plan on using the Metal Detector for a week or more.

Testing Batteries:

Always test the battery power when the Metal Detector does not turn on, has weak volume, will not tune properly, or has erratic operation.

Rotate VOLUME away from OFF and set OPERATE / BATT to BATT TEST (see Figure 7).

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:

Stereo earphones (not included) can be connected to the Metal Detector. Using earphones saves battery power and makes it easier to identify changes in the sound patterns. Earphones are connected to the ear jack on the side of the Control Housing (see Figure 8). When using earphones, protect your hearing by:

a.Set the volume to the lowest setting before you begin listening. Adjust the volume to a comfortable level.

b.Never listen at extremely high volume levels; permanent hearing loss can result.

c.Once the volume is set, 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.
