The Control Panel contains the following switches and indicators for overall control of the system:

CYCLE TIME SWITCH - A four position switch that turns the unit on and selects the cycle time.

Pos 1) OFF. In this position all power is removed from the system. When recharging the battery, this switch

should be turned off.

Pos 2,3,4) Power is on and the unit cycles (takes a reading) every 2, or 5, or 10 seconds. Battery lasts longest

in the 10 second position. In the 2 second position, readings are taken the most often. The 2 second
position is recommended when pinpointing a target.

SENSITIVITY SWITCH - A four position switch to allow adjustment of the sensitivity of the unit.  In most cases it is
desirable to operate at its maximum sensitivity setting of 1 gamma.  Once a large target is detected, you may want to
turn down the sensitivity to enable you to more easily pinpoint the target.

G1  - A one digit change indicates a one gamma change.  Most sensitive position, used to locate small targets.

Best position for general searching.

G5  - The gamma reading is divided by 5 before it is displayed. A one digit change in the readout indicates a

five gamma change.  More stable than G1, used for most magging operations if in noisy area.

G10 - The gamma reading is divided by 10 before it is displayed. A one digit change in the readout indicates a

ten gamma change. Used in pinpointing targets or when you are looking  for a large target in a small area.

G20 - The gamma reading is divided by 20 before it is displayed. A one digit change in the readout indicates a

twenty gamma change.  Used in pinpointing large targets.

         If you were in Miami, Florida area, you would get an approximate reading (see map) of:

G1   = 49,138
G5   = 9,827
G10 = 4,914
G20 = 2,457

         If you were in the Miami area approaching a large ship:
