Using the Lmic
The Lmic is simple to operate. Select either the probe
rods or the tripod unit and screw into the microphone
unit. (Use the tripod foot on hard ground and use the
probe rods on soft ground or when accessing water
pipe fittings). Connect the headphones to the rear
connector and connect the microphone cable to the
forward connector. Put on the headphones and press
the trigger button underneath the hand-held unit to
listen for leaks. The volume/sensitivity can be
adjusted using the rotary control.
LED indication
The green LED shows when the unit is operating and
the red LED indicates low battery power.
Care of the Lmic
The Lmic is rugged and showerproof (to IP65) but
contains electronic circuitry and should be handled
with care. It should be kept clean and dry and where
necessary cleaned with a damp cloth; abrasive
materials must not be used.
Battery Warning
The Lmic contains lithium ion batteries which must not be used under any circumstances on any other equip-
ment if removed. Only batteries supplied by Palmer Environmental must be used as replacements. Do not short
circuit or misuse these batteries as this may result in explosion or fire.
Battery replacement
Although these batteries are rechargeable they may eventually need to be replaced. To do this undo the two
screws underneath the hand-held unit and separate the two halves of the Lmic unit. Gently pull out the battery
holder and replace the batteries. When refitting the batteries and battery holder make sure no wires become
trapped.
Charging the Lmic batteries
Connect the charger lead to the rear connector of the Lmic and connect the charger power lead to the 240V AC
supply. The Lmic can then be charged overnight. An optional accessory is the car cigarette lighter adapter that
can also be used to charge the batteries.
