Taking Care
34
of Your Detector
The Excalibur II is a high quality electronic instrument.
Take care of your detector in the following way:
• Visually check the lower end of both cylinders after entering the water. If
any water droplets or condensation are visible inside your Excalibur II,
turn it off and remove it from the water immediately. Remove your
batteries and contact your Minelab dealer immediately.
• The battery and control cylinder have been sealed and pressure tested.
Never open or tamper with the sealed electronics and battery cylinders,
as this will void the warranty.
• If water or condensation is present in the end caps through the small
screw, contact your Minelab dealer. If it appears outside the rubber O-ring
seal it is OK.
• Avoid rapid changes in temperature. Gradual warming and cooling will
keep the internal atmosphere stable. Extreme temperature swings may
cause a light condensation to appear on the cylinder walls for a short
time. Wait for this to disappear before using your Excalibur II.
• Never leave your Excalibur II in direct sunlight as it can reach very high
temperatures, causing irreparable damage to your coil.
• Salt deposits, very fine sand, and grit will accumulate on the Excalibur II.
Thoroughly rinsing your detector with fresh water after each use is
necessary. Disconnect the shafts, battery pack, and armrest, and flush
out all salt and sand, especially in the battery terminals. Also ensure that
the vent holes on each headphone diaphragm are rinsed and clear of
sediment. This is critical to allow for ear equalization when the Excalibur II
is used for underwater detection at depth.
Taking Care
of Your Battery
• The NiMH battery pack has been sealed and pressure tested and should
not be disassembled.
• Never allow the cables to be jerked or snagged. Excessive tension could
cause the watertight seals or cable to fail.
• When disconnecting batteries, always grip the plug body, never the cable.
• As part of the manufacturing process, Minelab applies a silicone grease to
the battery cable connector pins. This prevents a build-up of residual
water and reduces the level of electrolysis between the two pins, which
in turn prolongs the serviceability of your unit. This grease should be
reapplied as part of your routine care and maintenance.
• It is recommended to recharge the battery every 3-6 months if not in
regular use.
• Do not immerse the battery in any liquid when disconnected from the
Excalibur II or allow water to enter.
• Do not use battery if there is condensation visible inside the battery pack.
• Do not use the battery if it is damaged or deformed.
• Do not charge the battery at temperatures above 45°C (113°F)
or below 0°C (32°F).
• Do not leave the battery in hot environmental conditions (e.g. on the
dashboard of your car or rear parcel shelf).
• Do not throw the battery or impact it in any way.
• Do not short-circuit the battery.
• Do not incinerate the battery.
• Return the battery to a Minelab authorised service centre for repair.
The use of non-approved components will VOID YOUR WARRANTY.
There are no user serviceable parts within this battery pack.
