DX-300 – DIVER HELD MAGNETOMETER

N.B. THE CURRENT TYPE OF CHARGERS SUPPLIED (JAN 2011

ONWARDS) PROVIDE A CONSTANT RATE OF CHARGE FOR UP TO 14

HOURS; FOLLOWED BY A TRICKLE CHARGE (MAINTENANCE)

MODE. WHILST CHARGING AT THE REGULAR RATE THE LED

LIGHT WILL GLOW ORANGE, ONCE THE CHARGING PERIOD BEEN

COMPLETED THE CHARGER DROPS INTO "TOP UP" CHARGE

MODE, AT THIS STAGE THE LIGHT CHANGES TO GREEN WITH A

YELLOW FLASH.

During subsequent partial recharge/top up requirements; batteries will not be

damaged by being left on charge for a longer period than necessary, this is due

to the controlled charge current being automatically followed by a trickle charge

mode. If the batteries become fully discharged - due to natural extended usage

or through the unit accidentally being left in the on state – the unit should be

fully recharged as soon as possible to avoid irreparable damage to the battery

cells.

N.B. DO NOT USE ANY BATTERY CHARGER OTHER THAN THAT

SUPPLIED; AS THIS COULD RESULT IN DAMAGE TO THE BATTERY

PACK.

When the charge period has elapsed, disconnect the AC supply to the charger

first, and then unplug the connector from the socket on the detector. Charging

can be terminated before the 14 hour period has elapsed if the unit just requires a

top up charge. NB. The operational usage time on a full charge with a healthy

battery pack will be in the order of 24 hours, recharging will require a 1 hour

charge time for each 2 hours of usage; in other words a 2:1 usage/charge time to

replenish. Some earlier types of charger had a 6 hour time out period requiring

the charger to be switched off and back on to extend the charging to periods

exceeding the 6 hour cut off.

2. For initial testing on land, you will have to find a location where you can position

yourself at least 20 metres from any large ferrous objects in all directions. Get rid

of anything containing ferrous/magnetic items on your body or in your clothing –

and leave your mobile/cell phone well out of range. An empty farm field, park,

sports field or beach is ideal for testing. If possible park your car at the edge of

the field (at least 20 metres from where you will be testing), or find a location

where there is some large ferrous target in one direction only.

3. To prepare the DX-300 for use, plug the connector on the Sensor Probe into the

SENSOR socket and screw down the retaining collar. This should be good finger

tightness only.

N.B.PLIERS OR OTHER TOOLS SHOULD NOT BE USED TO TIGHTEN THE

PLUG COLLARS. THESE ARE DESIGNED TO BE USED FINGER TIGHT

WITH THE BLACK RUBBER BULKHEAD SEAL IN PLACE ON THE

PLUG PINS.
