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)
