ASF-G

3. Safety Instructions

For your own safety and trouble-free use of the

Ambient Sound Fish please carefully read the

instructions below. Always keep a copy of these

instructions and hand them out with the unit to

other users.

This unit is intended for use in water on a professional underwater housing with M14 bulkhead. When

screwed on correctly and locked tight, it is sealed to be waterproof down to a depth of up to 100m.

Anyway, always long-term test the sealing in shallow water and replace damaged sealing gaskets

before actual field usage. Always make sure that the receptacles are kept dry and clean. It is

recommended to use a small amount of silicone based lubricant on the thread to ensure

waterproofness. Note that the lubricant needs to be removed thoroughly after each unscrewing. Switch

off the Phantom Power before disconnecting the hydrophone.

Seawater is a very aggressive medium. Even though the ASF-G is only manufactured with materials

offering a good seawater resistance, the unit has to be cleaned immediately after use in sea or chlorine

water with plenty of fresh water to avoid irrevocable damage. Sea water could cause superficial

corrosion that might change the color of the anodized aluminum housing. This is a natural process

which won't damage the unit nor affect the usability. If the corrosion is starting to dissolve the metal,

stop using the ASF-G immediately and check if the housing is connected to any ground. (More info in

"4. Powering")

Never use the hydrophone within acids or bases. Never bend the acoustic sensitive membrane in any

way. Keep out of hot environments and never expose to direct sunlight. Do not throw the hydrophone

or expose to mechanical impact. Do not expose to hard vibrations.

Operating ambient temperature: -5°C to +50°C (23°F to 122°F)

Only use genuine accessories (such as cables) supplied by an authorized dealer. Always check integrity

and proper compatibility with all units connected to. Never open the unit. Inappropriate and

unauthorized access will void the warranty and imply possible risks of harm to the user.

Follow the legal requirements for recycling electronic equipment when disposing the unit.
