2 Quick start guide
2.1 Opening and closing the housing
Before opening the housing always check for flooding by shaking the recorder and listening for water
sloshing around inside. If flooding is suspected, then be aware that the housing may be pressurised
and therefore potentially dangerous. Carefully relieve any pressure by opening the small seal screw
at the base of the housing.
Opening the housing :
•
Find the ‘open this end’ sticker on the housing.
•
Screw open the endcap by turning counter clockwise
•
You will probably need to insert a lever arm (eg screwdriver) in the provided holes to gain
sufficient leverage.
Closing the housing :
•
Carefully check the O’ring s. Any nicks or scratches indicate they must be replaced.
•
Lubricate O’rings with silicone grease.
•
Check O’rings are properly seated and absolutely free of stray hair/grit etc
•
Insert the chassis in the housing and screw all the way home, using a lever arm if necessary.
•
Difficulty in screwing home the cap may indicate insufficient o’ring lubrication; do not apply
excessive force – instead correct by applying o’ring lubricant.
•
Replacement O’Rings should be type 78x3 N70 (Nitrile)
The O’ring checks are critically important to avoid damage. Any detritus or damage to the O’rings
may result in the housing being flooded which will almost certainly destroy the electronics.
